Bugsnag C# (Funktionsweise für Entwickler)

Configure Bugsnag C# in .NET Projects

To begin, you need to add Bugsnag to your project. This is done by installing the Bugsnag package from NuGet, which is the package manager for .NET. Go to the NuGet console in Visual Studio. Run the following command:

Install-Package Bugsnag

A Basic Code Example

After installing Bugsnag, the next step is to configure it within your application, making your Bugsnag configuration a private readonly Bugsnag instance for enhanced security and control. To initialize your project with the Bugsnag client, you must first obtain a Bugsnag API key. This connects your application to the Bugsnag dashboard.

using Bugsnag;

namespace YourNamespace
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize Bugsnag configuration with your API key
            var settings = new Configuration("api_key_here");
            var client = new Client(settings);

            // Example of manually notifying Bugsnag of an issue
            try
            {
                // Your code here. For example:
                throw new System.NotImplementedException("This is a test exception.");
            }
            catch (System.Exception ex)
            {
                // Notify Bugsnag of the exception
                client.Notify(ex);
            }
        }
    }
}

using Bugsnag;

namespace YourNamespace
{
    class Program
    {
        static void Main(string[] args)
        {
            // Initialize Bugsnag configuration with your API key
            var settings = new Configuration("api_key_here");
            var client = new Client(settings);

            // Example of manually notifying Bugsnag of an issue
            try
            {
                // Your code here. For example:
                throw new System.NotImplementedException("This is a test exception.");
            }
            catch (System.Exception ex)
            {
                // Notify Bugsnag of the exception
                client.Notify(ex);
            }
        }
    }
}

Imports Bugsnag

Namespace YourNamespace
	Friend Class Program
		Shared Sub Main(ByVal args() As String)
			' Initialize Bugsnag configuration with your API key
			Dim settings = New Configuration("api_key_here")
			Dim client As New Client(settings)

			' Example of manually notifying Bugsnag of an issue
			Try
				' Your code here. For example:
				Throw New System.NotImplementedException("This is a test exception.")
			Catch ex As System.Exception
				' Notify Bugsnag of the exception
				client.Notify(ex)
			End Try
		End Sub
	End Class
End Namespace

This code snippet demonstrates how to set up Bugsnag in a simple .NET console application. The Bugsnag notifier's Notify method sends the caught exception to Bugsnag. Not only does it report exceptions in production, but it also allows you to see the error in the Bugsnag dashboard, streamlining the exception handling.

Now that you have Bugsnag set up and ready to report errors, let's delve into its features and how you can use them to monitor your application effectively.

Automatic Error Reporting

One of the core advantages of Bugsnag is its ability to automatically capture and report uncaught exceptions. This means that any exceptions thrown in your application that you do not catch manually will still be reported to the Bugsnag dashboard. Here’s how you can enable automatic error reporting:

var settings = new Configuration("your_bugsnag_api_key_here")
{
    AutoCaptureSessions = true // Automatically captures and reports sessions
};
var client = new Client(settings);

var settings = new Configuration("your_bugsnag_api_key_here")
{
    AutoCaptureSessions = true // Automatically captures and reports sessions
};
var client = new Client(settings);

Dim settings = New Configuration("your_bugsnag_api_key_here") With {.AutoCaptureSessions = True}
Dim client As New Client(settings)

This configuration ensures that every session is monitored, and any uncaught exceptions are automatically reported, providing you with a comprehensive overview of your application's stability.

Configuration Options for Detailed Error Control

Customizing how Bugsnag reports errors can greatly improve the usefulness of the error information you receive. Bugsnag C# offers various configuration options to refine error reporting. For example, you can specify which exceptions to ignore, add custom diagnostics information, and control the amount of user data sent with error reports:

var settings = new Configuration("your_bugsnag_api_key_here")
{
    ProjectNamespaces = new[] { "YourNamespace" }, // Only report errors from specific namespaces
    IgnoreClasses = new[] { "System.Exception" }, // Ignore specific exception types
    ReleaseStage = "production" // Set the current release stage of your application
};

var settings = new Configuration("your_bugsnag_api_key_here")
{
    ProjectNamespaces = new[] { "YourNamespace" }, // Only report errors from specific namespaces
    IgnoreClasses = new[] { "System.Exception" }, // Ignore specific exception types
    ReleaseStage = "production" // Set the current release stage of your application
};

Dim settings = New Configuration("your_bugsnag_api_key_here") With {
	.ProjectNamespaces = { "YourNamespace" },
	.IgnoreClasses = { "System.Exception" },
	.ReleaseStage = "production"
}

This setup helps in focusing on the errors that matter most to your application while ensuring user privacy and data security.

Enhancing Error Reports with User Data and Metadata

Adding user information and custom metadata to your error reports can provide valuable context, making it easier to diagnose and fix issues. Here's how you can enhance your error reports:

client.BeforeNotify(report =>
{
    report.Event.User = new User { Id = "user_id", Name = "User Name", Email = "user@example.com" };
    report.Event.AddMetadata("Order", new { OrderId = 123, Status = "Processing" });
});

client.BeforeNotify(report =>
{
    report.Event.User = new User { Id = "user_id", Name = "User Name", Email = "user@example.com" };
    report.Event.AddMetadata("Order", new { OrderId = 123, Status = "Processing" });
});

client.BeforeNotify(Sub(report)
	report.Event.User = New User With {
		.Id = "user_id",
		.Name = "User Name",
		.Email = "user@example.com"
	}
	report.Event.AddMetadata("Order", New With {
		Key .OrderId = 123,
		Key .Status = "Processing"
	})
End Sub)

This code snippet adds user details and custom metadata about an order to every error report. This additional context can be crucial for understanding the circumstances that led to an error.

By leveraging these features of Bugsnag C#, you can gain deeper insights into the errors affecting your application, prioritize fixes based on real user impact, and ultimately improve the reliability and user experience of your software.

        _bugsnagClient = bugsnagClient;
    }

    public void GeneratePdfFromHtml(string htmlContent)
    {
        try
        {
            // Use IronPDF to render HTML as PDF
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf(htmlContent);

            // Save the rendered PDF to a file
            pdf.SaveAs("example.pdf");
        }
        catch (Exception ex)
        {
            // Notify Bugsnag of the exception
            _bugsnagClient.Notify(ex);

            // Optionally re-throw the exception for further handling
            throw;
        }
    }
}

using IronPdf;
using Bugsnag;

public class PdfGenerator
{
    private readonly IClient _bugsnagClient;

    public PdfGenerator(IClient bugsnagClient)
    {
        _bugsnagClient = bugsnagClient;
    }

    public void GeneratePdfFromHtml(string htmlContent)
    {
        try
        {
            // Use IronPDF to render HTML as PDF
            var renderer = new ChromePdfRenderer();
            var pdf = renderer.RenderHtmlAsPdf(htmlContent);

            // Save the rendered PDF to a file
            pdf.SaveAs("example.pdf");
        }
        catch (Exception ex)
        {
            // Notify Bugsnag of the exception
            _bugsnagClient.Notify(ex);

            // Optionally re-throw the exception for further handling
            throw;
        }
    }
}

Imports IronPdf
Imports Bugsnag

Public Class PdfGenerator
	Private ReadOnly _bugsnagClient As IClient

	Public Sub New(ByVal bugsnagClient As IClient)
		_bugsnagClient = bugsnagClient
	End Sub

	Public Sub GeneratePdfFromHtml(ByVal htmlContent As String)
		Try
			' Use IronPDF to render HTML as PDF
			Dim renderer = New ChromePdfRenderer()
			Dim pdf = renderer.RenderHtmlAsPdf(htmlContent)

			' Save the rendered PDF to a file
			pdf.SaveAs("example.pdf")
		Catch ex As Exception
			' Notify Bugsnag of the exception
			_bugsnagClient.Notify(ex)

			' Optionally re-throw the exception for further handling
			Throw
		End Try
	End Sub
End Class

In this example, ChromePdfRenderer is used to convert HTML content to a PDF. If something goes wrong, BugSnag's Notify method is called, logging the exception without interrupting the application flow.
