Once installed, you can configure your server instance. Create a new configuration file named appsettings.json. This file will define the server settings, including the listeners and protocols.

{
  "serverOptions": {
    "name": "SuperSocketServer",
    "listeners": [
      {
        "ip": "Any",
        "port": 4040
      }
    ]
  }
}

Next, create a class to configure the server. This class will read the settings from appsettings.json and initialize the server instance.

public class ServerConfig
{
    public async Task Configure()
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<YourSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class ServerConfig
{
    public async Task Configure()
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<YourSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class ServerConfig
	Public Async Function Configure() As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of YourSession)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

A Basic SuperSocket C# Example

Let's look at a basic example of a SuperSocket C# application. This example demonstrates how to create a simple echo server that sends back any received data.

First, define the session class. This class will handle the socket connections and manage data communication.

public class EchoSession : AppSession
{
    protected override async ValueTask OnSessionStartedAsync()
    {
        await base.OnSessionStartedAsync();
        Console.WriteLine("New session started.");
    }
    protected override async ValueTask OnSessionClosedAsync(CloseEventArgs e)
    {
        await base.OnSessionClosedAsync(e);
        Console.WriteLine("Session closed.");
    }
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        await SendAsync(package);
    }
}

public class EchoSession : AppSession
{
    protected override async ValueTask OnSessionStartedAsync()
    {
        await base.OnSessionStartedAsync();
        Console.WriteLine("New session started.");
    }
    protected override async ValueTask OnSessionClosedAsync(CloseEventArgs e)
    {
        await base.OnSessionClosedAsync(e);
        Console.WriteLine("Session closed.");
    }
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        await SendAsync(package);
    }
}

Public Class EchoSession
	Inherits AppSession

	Protected Overrides Async Function OnSessionStartedAsync() As ValueTask
		Await MyBase.OnSessionStartedAsync()
		Console.WriteLine("New session started.")
	End Function
	Protected Overrides Async Function OnSessionClosedAsync(ByVal e As CloseEventArgs) As ValueTask
		Await MyBase.OnSessionClosedAsync(e)
		Console.WriteLine("Session closed.")
	End Function
	Protected Overrides Async Function OnPackageReceivedAsync(ByVal package As ReadOnlyMemory(Of Byte)) As ValueTask
		Await SendAsync(package)
	End Function
End Class

Next, configure and run the server with the echo session.

public class EchoServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<EchoSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class EchoServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<EchoSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class EchoServer
	Public Shared Async Function Main(ByVal args() As String) As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of EchoSession)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

This example shows how to create a simple echo server using SuperSocket C#. The server listens for connections and echoes back any data it receives.

Implementing Features of SuperSocket C

Handling Multiple Listeners

SuperSocket C# supports multiple listeners, allowing your server to handle different protocols and ports. This feature is useful for creating versatile applications like data acquisition servers and GPS servers.

First, update your appsettings.json to include multiple listeners:

{
  "serverOptions": {
    "name": "MultiListenerServer",
    "listeners": [
      {
        "ip": "Any",
        "port": 4040
      },
      {
        "ip": "Any",
        "port": 5050
      }
    ]
  }
}

Next, configure the server to use these listeners:

public class MultiListenerServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<YourSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class MultiListenerServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<YourSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class MultiListenerServer
	Public Shared Async Function Main(ByVal args() As String) As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of YourSession)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

With this setup, your server can handle connections on both ports 4040 and 5050. This capability is crucial for applications that need to manage various network protocols.

Implementing Binary Data Handling

SuperSocket C# is efficient at handling binary data. This is important for applications that require binary-level compatibility, such as industrial control systems.

First, define a session class that processes binary data:

public class BinaryDataSession : AppSession
{
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        var data = package.ToArray();
        Console.WriteLine("Received binary data: " + BitConverter.ToString(data));
        await SendAsync(data);
    }
}

public class BinaryDataSession : AppSession
{
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        var data = package.ToArray();
        Console.WriteLine("Received binary data: " + BitConverter.ToString(data));
        await SendAsync(data);
    }
}

Public Class BinaryDataSession
	Inherits AppSession

	Protected Overrides Async Function OnPackageReceivedAsync(ByVal package As ReadOnlyMemory(Of Byte)) As ValueTask
		Dim data = package.ToArray()
		Console.WriteLine("Received binary data: " & BitConverter.ToString(data))
		Await SendAsync(data)
	End Function
End Class

Next, configure and run the server with the binary data session:

public class BinaryDataServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<BinaryDataSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class BinaryDataServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<BinaryDataSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class BinaryDataServer
	Public Shared Async Function Main(ByVal args() As String) As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of BinaryDataSession)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

This example demonstrates how to receive and send binary data using SuperSocket C#. It's useful for high-performance applications that need to process binary protocols.

Managing Socket Connections

Maintaining socket connections is essential for ensuring reliable communication. SuperSocket C# simplifies this process.

First, define a session class that manages socket connections:

public class ConnectionSession : AppSession
{
    protected override async ValueTask OnSessionStartedAsync()
    {
        await base.OnSessionStartedAsync();
        Console.WriteLine("Connection started.");
    }
    protected override async ValueTask OnSessionClosedAsync(CloseEventArgs e)
    {
        await base.OnSessionClosedAsync(e);
        Console.WriteLine("Connection closed.");
    }
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        await SendAsync(package);
    }
}

public class ConnectionSession : AppSession
{
    protected override async ValueTask OnSessionStartedAsync()
    {
        await base.OnSessionStartedAsync();
        Console.WriteLine("Connection started.");
    }
    protected override async ValueTask OnSessionClosedAsync(CloseEventArgs e)
    {
        await base.OnSessionClosedAsync(e);
        Console.WriteLine("Connection closed.");
    }
    protected override async ValueTask OnPackageReceivedAsync(ReadOnlyMemory<byte> package)
    {
        await SendAsync(package);
    }
}

Public Class ConnectionSession
	Inherits AppSession

	Protected Overrides Async Function OnSessionStartedAsync() As ValueTask
		Await MyBase.OnSessionStartedAsync()
		Console.WriteLine("Connection started.")
	End Function
	Protected Overrides Async Function OnSessionClosedAsync(ByVal e As CloseEventArgs) As ValueTask
		Await MyBase.OnSessionClosedAsync(e)
		Console.WriteLine("Connection closed.")
	End Function
	Protected Overrides Async Function OnPackageReceivedAsync(ByVal package As ReadOnlyMemory(Of Byte)) As ValueTask
		Await SendAsync(package)
	End Function
End Class

Next, configure and run the server with the connection session:

public class ConnectionServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<ConnectionSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class ConnectionServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<ConnectionSession>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class ConnectionServer
	Public Shared Async Function Main(ByVal args() As String) As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of ConnectionSession)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

This setup helps manage socket connections, ensuring that your server remains robust and reliable.

Creating a Command-Line Server

SuperSocket C# supports creating command-line servers. This feature is useful for applications that require simple text-based protocols.

First, define a command class that processes text commands:

public class MyCommand : IAsyncCommand<AppSession, StringPackageInfo>
{
    public async ValueTask ExecuteAsync(AppSession session, StringPackageInfo package)
    {
        var commandKey = package.Key;
        var parameters = package.Parameters;
        await session.SendAsync(Encoding.UTF8.GetBytes($"You said: {string.Join(' ', parameters)}"));
    }
}

public class MyCommand : IAsyncCommand<AppSession, StringPackageInfo>
{
    public async ValueTask ExecuteAsync(AppSession session, StringPackageInfo package)
    {
        var commandKey = package.Key;
        var parameters = package.Parameters;
        await session.SendAsync(Encoding.UTF8.GetBytes($"You said: {string.Join(' ', parameters)}"));
    }
}

Public Class MyCommand
	Implements IAsyncCommand(Of AppSession, StringPackageInfo)

	Public Async Function ExecuteAsync(ByVal session As AppSession, ByVal package As StringPackageInfo) As ValueTask
		Dim commandKey = package.Key
		Dim parameters = package.Parameters
		Await session.SendAsync(Encoding.UTF8.GetBytes($"You said: {String.Join(" "c, parameters)}"))
	End Function
End Class

Next, configure the server to use the command:

public class CommandLineServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<AppSession>()
            .UseCommand<StringPackageParser>()
            .AddCommand<MyCommand>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

public class CommandLineServer
{
    public static async Task Main(string[] args)
    {
        var host = SuperSocketHostBuilder.Create()
            .UseTcpServer()
            .UseSession<AppSession>()
            .UseCommand<StringPackageParser>()
            .AddCommand<MyCommand>()
            .ConfigureAppConfiguration((hostCtx, configApp) =>
            {
                configApp.AddJsonFile("appsettings.json", optional: false, reloadOnChange: true);
            })
            .Build();
        await host.RunAsync();
    }
}

Public Class CommandLineServer
	Public Shared Async Function Main(ByVal args() As String) As Task
		Dim host = SuperSocketHostBuilder.Create().UseTcpServer().UseSession(Of AppSession)().UseCommand(Of StringPackageParser)().AddCommand(Of MyCommand)().ConfigureAppConfiguration(Sub(hostCtx, configApp)
				configApp.AddJsonFile("appsettings.json", [optional]:= False, reloadOnChange:= True)
		End Sub).Build()
		Await host.RunAsync()
	End Function
End Class

This example shows how to create a simple command-line server using SuperSocket C#. It's ideal for lightweight text-based protocols.

namespace SuperSocketIronPDFExample
{
    class Program
    {
        static void Main(string[] args)
        {
            var appServer = new AppServer();
            var serverConfig = new ServerConfig
            {
                Name = "SuperSocketServer",

                Mode = SocketMode.Tcp,
                MaxConnectionNumber = 100,
            };
            if (!appServer.Setup(serverConfig))
            {
                Console.WriteLine("Failed to set up!");
                return;
            }
            appServer.NewSessionConnected += NewSessionConnected;
            appServer.NewRequestReceived += NewRequestReceived;
