Setting up WebSocket events is a crucial step in establishing a successful connection. You need to access the e.Data or e.RawData property to get the message data.

The e.Data property returns a string, making it perfect for getting text message data. On the other hand, the e.RawData property returns a byte[], which is ideal for receiving binary message data.

To notify that a ping has been received, you should set the WebSocket.EmitOnPing property to true. This way, you'll be notified whenever a ping is received.

The WebSocket connection can be closed due to various reasons. If you want to get the reason for closure, you should access the e.Code or e.Reason property. The e.Code property returns a ushort that represents the status code for the close, while the e.Reason property returns a string that represents the reason for the close.

A WebSocket.OnOpen event occurs when the WebSocket connection has been established. This event doesn't require any information from the e parameter.

The WebSocket connection can receive various types of messages, including text and binary messages. To determine the type of message, you should check the e.Type property. If the e.Type equals Opcode.TEXT, you should use the e.Data property to get the text message data. If the e.Type equals Opcode.BINARY, you should use the e.RawData property to get the binary message data.

The WebSocket connection can get an error due to various reasons. If you want to get the error message, you should access the e.Message property. The e.Message property returns a string that represents the error message.

The WebSocket connection can be closed due to various reasons. If you want to get the reason for closure, you should access the e.Code or e.Reason property. The e.Code property returns a ushort that represents the status code for the close, while the e.Reason property returns a string that represents the reason for the close.

Suggestion: Websocket Use Cases

Per-message Compression is a feature that allows for efficient data transfer over WebSockets. It's supported by websocket-sharp, but only for the Per-message Compression extension.

To enable this feature as a WebSocket client, you need to set the WebSocket.Compression property to a compression method before calling the connect method. This sends a specific header in the handshake request to the server.

If the server supports this extension, it will return the same header with the corresponding value in the handshake response. This enables the extension on the client side.

Here's a step-by-step guide to enabling Per-message Compression:

If you want to ignore the extensions requested from a client as a WebSocket server, you can set the WebSocketBehavior.IgnoreExtensions property to true. This will prevent the server from returning the Sec-WebSocket-Extensions header in its handshake response.

Authentication is a crucial aspect of WebSocket communication, ensuring that only authorized users can connect to a WebSocket server.

As a WebSocket client, you can set a pair of user name and password for HTTP authentication using the WebSocket.SetCredentials method before connecting.

If you set preAuth to true, the client will send Basic authentication credentials in the first handshake request to the server.

To set up HTTP authentication on the server side, you need to specify an HTTP authentication scheme, a realm, and a function to find user credentials before starting the WebSocket service.

If you want to provide Digest authentication, you should set up the server with the necessary settings.

Connecting to a WebSocket server is a crucial step in the authentication process. You should use the WebSocket.ConnectAsync () method to connect to the server asynchronously.

This method allows for efficient and reliable connections, which is essential for a secure authentication system.

Connecting asynchronously helps prevent delays and ensures a seamless user experience.

To establish a secure connection, you should create a WebSocket client instance with a wss scheme WebSocket URL.

Using a wss scheme ensures that your connection is encrypted.

If you want to set a custom validation for the server certificate, you should set the WebSocket.SslConfiguration.ServerCertificateValidationCallback property to a callback for it.

This property should be set to a callback that checks the server's certificate for validity.

If you don't set this property, the default callback will always return true, effectively disabling certificate validation.

As a WebSocket server, you should create a new instance of the WebSocketServer or HttpServer class with some settings for the secure connection.

This might include specifying a certificate file or using a self-signed certificate.

By following these steps, you can establish a secure connection with your WebSocket server and protect your data from unauthorized access.

If you set preAuth to true, the client will send the credentials for the Basic authentication in the first handshake request to the server. This ensures that the client is authenticated from the very start.

As a WebSocket server, you should set an HTTP authentication scheme, a realm, and any function to find the user credentials before starting. This will allow the server to verify the client's credentials and grant access accordingly.

If you want to provide Digest authentication, you should set it up like this.

websocket-sharp is a robust and reliable choice for WebSocket communication, with a wide range of features and dependencies to support your development needs.

WebSockets can be used in C# to establish real-time communication between a client and a server.

In a WebSocket connection, data is sent in both directions simultaneously, allowing for efficient communication.

This is particularly useful for applications that require live updates, such as live scores or stock prices.

The WebSocket protocol uses a handshake to establish the connection, which includes a unique identifier for the connection.

Branches are a way to organize different versions of your code, and in the context of WebSocket connections, there are several branches to be aware of.

The master branch is used for production releases.

Older branches include hybi-00, which is no longer maintained, and draft75, also no longer maintained.

Here are the branches mentioned, listed out for easy reference:

Ignoring the extensions can be a useful approach when troubleshooting WebSocket connection issues. If you set the WebSocketBehavior.IgnoreExtensions property to true, the service will not return the Sec-WebSocket-Extensions header in its handshake response.

This means you can exclude extensions as a possible cause of errors. For example, if you encounter an error in connecting the server, you can try ignoring extensions to see if it resolves the issue.

Server Configuration is a crucial step in setting up your WebSocket Sharp project. You need to ensure that your server is properly configured to handle WebSocket connections.

To start, you'll need to install the WebSocket Sharp library using NuGet. This will give you access to the necessary classes and methods for working with WebSockets.

When configuring your server, you'll want to consider the protocol version. WebSocket Sharp supports both the WebSocket protocol version 13 and the HyBi protocol version 10. You can specify the protocol version when creating a new WebSocket server.

You can also customize the server's settings, such as the maximum number of connections allowed and the buffer size. This will help you optimize your server's performance and prevent resource overload.
