TCP .NET (How It Works For Developers)

Introduction

Modern software programs must be able to send data over networks reliably and efficiently in the linked world of today. The internet's primary networking protocol, TCP/IP, offers a stable framework for data transfer in a variety of network conditions. Device communication is made possible by this suite of protocols, which supports a number of use cases including file transmission, remote access, and real-time communication.

Conversely, IronPDF is a feature-rich .NET library for creating and modifying PDF files. IronPDF is a useful tool for document generating, reporting, and data visualization activities since it allows developers to dynamically create PDF files from HTML content, URLs, or raw data.

In this post, we explore how to integrate IronPDF with TCP .Net to facilitate effective document generation in .NET applications. By merging these technologies, programmers can increase productivity and scalability in their applications by using network communication to obtain data, work with distant systems, and create dynamic PDF pages.

How to use TCP/IP communication

1. Create a new C# project in Visual Studio.
2. Import the namespace System.Net and System.Net.Sockets.
3. Create a TCP server and TCP client program. Specify the IP address and port number.
4. Send the message from the server to the client. Log the server message from the client into the report.
5. Close the connections.

Introduction to TCP .NET

A set of communication protocols known as TCP/IP (Transmission Control Protocol/Internet Protocol) regulates the sending and receiving of data via networks, mainly the Internet. A standardized framework for computer and device communication is provided by TCP/IP, allowing data to be sent across networks that are connected. There are various layers of TCP/IP, and each one is in charge of handling particular facets of communication.

The Internet Protocol (IP), which manages data packet addressing and routing between devices on a network, is the fundamental component of TCP/IP. Each device connected to the network is given a unique IP address, or network address, by IP, which enables data to be transferred to and received from specified locations.

Features of TCP protocol

1. Dependability

Sequence numbers, acknowledgments, and retransmissions are only a few of the techniques that TCP uses to guarantee dependable data delivery. A sender delivers data packets and then waits for the recipient to acknowledge the packet as successfully delivered. To make sure the data packet is delivered, the sender retransmits it if an acknowledgment is not received in a predetermined amount of time. This reliability mechanism aids in avoiding transmission-related data loss or corruption.

2. Connection-Oriented Communication

Before sending data, TCP protocol creates a connection between the sender and the recipient. In order to establish synchronization and decide on communication settings, the sender and receiver engage in a three-way handshake process during the connection setup. Data can be transferred back and forth between the parties until the connection is broken.

3. Flow management

To manage the speed at which data is sent from the sender to the recipient, TCP uses flow control methods. Flow control uses sliding window methods to stop the sender from sending too much data to the recipient. The sender can modify its transmission rate by responding to the receiver's advertisement of its available buffer space. By doing this, network resources are used effectively and congestion or buffer overflow is avoided.

Getting Started with TCP

Creating a New Project in Visual Studio

To open the Visual Studio application, select the File menu. After selecting "New Project," choose "Console application."

After choosing the file location, type the project name in the assigned text field. Next, click the Create button after choosing the required .NET Framework, as seen in the sample below.

Setting Up TCP in C# Projects

The Network System.NET Base Class Library includes the sockets namespace, which should be available by default in your C# project. It offers classes on how to operate with sockets, which are network communication endpoints.

Implementing TCP in Windows console and forms

TCP is supported by a number of C# application types, including Windows Forms (WinForms) and Windows Console. Although each framework has a different implementation, the basic concept is always the same: TCP/IP acts as a container for communication between your application's client and server.

A Basic Example of Communication between client and server using TCP

TCP code is divided into two parts: one is the server, and another is the client. The server code sends the message to the client using the IP address and port, and the client receives the data and processes accordingly.

TCP server code

using System.Net;
using System.Net.Sockets;
System.Net.ServicePointManager.Expect100Continue = false;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
TcpClient client = new TcpClient();
client.Connect(endPoint);
NetworkStream stream = client.GetStream();
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine("Hello, Ironpdf");
writer.Flush();
Console.WriteLine("Message sent");
Console.ReadKey();

using System.Net;
using System.Net.Sockets;
System.Net.ServicePointManager.Expect100Continue = false;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
TcpClient client = new TcpClient();
client.Connect(endPoint);
NetworkStream stream = client.GetStream();
StreamWriter writer = new StreamWriter(stream);
writer.WriteLine("Hello, Ironpdf");
writer.Flush();
Console.WriteLine("Message sent");
Console.ReadKey();

Imports System.Net
Imports System.Net.Sockets
System.Net.ServicePointManager.Expect100Continue = False
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls12
Dim endPoint = New IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472)
Dim client As New TcpClient()
client.Connect(endPoint)
Dim stream As NetworkStream = client.GetStream()
Dim writer As New StreamWriter(stream)
writer.WriteLine("Hello, Ironpdf")
writer.Flush()
Console.WriteLine("Message sent")
Console.ReadKey()

Server code: we are creating a TCP server code that will send the data packets to the connected client. The above example shows that we are creating an object for the TCPClient class. To connect to the client, we pass the IP addresses and remote port number. It will create a socket connection with the TCP connection. Then the TCP servers send a message through the TCP socket.

TCP Client code

// TCP client code
using System.Net;
using System.Net.Sockets;
Console.WriteLine("Message from server : Hello, Ironpdf");
System.Net.ServicePointManager.Expect100Continue = false;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
TcpClient client = new TcpClient();
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
client.Connect(endPoint);
await using NetworkStream stream = client.GetStream();
StreamReader reader = new StreamReader(stream);
string response = reader.ReadLine();
Console.WriteLine(response);
Console.ReadKey();

// TCP client code
using System.Net;
using System.Net.Sockets;
Console.WriteLine("Message from server : Hello, Ironpdf");
System.Net.ServicePointManager.Expect100Continue = false;
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls | SecurityProtocolType.Tls11 | SecurityProtocolType.Tls12;
TcpClient client = new TcpClient();
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
client.Connect(endPoint);
await using NetworkStream stream = client.GetStream();
StreamReader reader = new StreamReader(stream);
string response = reader.ReadLine();
Console.WriteLine(response);
Console.ReadKey();

' TCP client code
Imports System.Net
Imports System.Net.Sockets
Console.WriteLine("Message from server : Hello, Ironpdf")
System.Net.ServicePointManager.Expect100Continue = False
System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls12
Dim client As New TcpClient()
Dim endPoint = New IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472)
client.Connect(endPoint)
Await using NetworkStream stream = client.GetStream()
Dim reader As New StreamReader(stream)
Dim response As String = reader.ReadLine()
Console.WriteLine(response)
Console.ReadKey()

In the above client code, which connects to the TCP socket and reads the string message received from the TCP server-internal buffering, and displays the entire message on the console. There is no default value for the idle timeout. We can set this, which helps us to close the connection after a specific time. Else it will wait until it receives any response from the server/client.

In the above code snippet, show the communication between the client and server and display the response on the console.

TCP protocol Operations

Socket Management

To connect and exchange data between endpoints, TCP sockets are utilized. To interact over TCP, applications must create, bind, listen on, accept, connect, and close sockets as needed.

Security

Data transported over a network can be encrypted using TCP and security protocols like TLS/SSL to guarantee confidentiality and integrity.

Flow Control

Using flow control methods, TCP makes sure the sender doesn't send too much data to the recipient. In order to do this, the amount of data that can be transferred before receiving an acknowledgment is constantly adjusted via TCP windowing.

Basic Client and server Connection

To connect to a TCP server, you can build a TCP client. For this, use the TcpClient class.

TcpClient client = new TcpClient();
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
client.Connect(endPoint);

TcpClient client = new TcpClient();
var endPoint = new IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472);
client.Connect(endPoint);

Dim client As New TcpClient()
Dim endPoint = New IPEndPoint(IPAddress.Parse("127.0.0.1"), 57472)
client.Connect(endPoint)

Integrating TCP with IronPDF

Using TCP and IronPDF together

When TCP/IP networking and PDF generation are integrated with IronPDF in a .NET application, developers can create PDF documents dynamically based on data received via a TCP/IP connection. Because this interface allows for real-time document creation and customization, it can be used for a variety of purposes, including the generation of statements, invoices, and reports based on real-time data streams.

Install IronPDF

• Open the Visual Studio project.

• Choose "Tools" > "NuGet Package Manager" > "Package Manager Console".

  • In the Package Manager Console, Enter the below command:

  Install-Package IronPdf

Implementing Logic

This integration enables real-time document creation and customization, making it suitable for various use cases such as generating reports, invoices, and statements based on live data streams.

1. Establishing Connection: A dependable, connection-oriented communication method is offered by TCP. Three steps are involved in the process of establishing a connection: SYN, SYN-ACK, and ACK. This guarantees that the server and client are prepared to exchange data.
2. Sending Data: Data can be transferred between endpoints once a connection has been made. TCP ensures that data will be sent correctly and in the correct order. Segments of the data are separated, transferred separately, and then assembled at the recipient.
3. Receiving Data: TCP buffers incoming data on the receiving end until the application can process it. Segments that are lost or corrupted are requested to be retransmitted by the recipient, who also acknowledges receiving the segments.
4. Save PDF and Notify: To create a PDF document dynamically based on supplied data, use IronPDF. With the data you have received, create HTML content or templates. Then, utilize IronPDF's API to turn that HTML content into a PDF document.

// IronPDF code here
var Renderer = new ChromePdfRenderer();
Renderer.RenderHtmlAsPdf("<h1>Dynamic PDF Document</h1><p>Data from network: "+ response+"</p>").SaveAs("document.pdf");
Console.ReadKey();

// IronPDF code here
var Renderer = new ChromePdfRenderer();
Renderer.RenderHtmlAsPdf("<h1>Dynamic PDF Document</h1><p>Data from network: "+ response+"</p>").SaveAs("document.pdf");
Console.ReadKey();

' IronPDF code here
Dim Renderer = New ChromePdfRenderer()
Renderer.RenderHtmlAsPdf("<h1>Dynamic PDF Document</h1><p>Data from network: " & response & "</p>").SaveAs("document.pdf")
Console.ReadKey()

To know more about the code example, refer to the IronPDF Documentation for Creating PDFs from HTML.
