websocket-sharp: WebSocket client and server open source library on the .NET platform

Recommend an open source project developed in C# to implement WebSocket function.

01 Project Introduction

websocket-sharp provides WebSocket client and server libraries, developed based on C# and following the WebSocket protocol specification, allowing developers to easily implement WebSocket communication in .NET applications.

The special functions of websocket-sharp are:

1. Simple and easy-to-use API: Provides a clear and intuitive API interface to facilitate developers to quickly integrate WebSocket. Whether creating a WebSocket client or server, it can be quickly implemented with a few lines of code.

2. Complete WebSocket protocol support: Follows the WebSocket protocol specification and supports all core functions defined in RFC 6455, including text and binary message transmission, Ping/Pong heartbeat mechanism, extensions and sub-protocols, etc.

3. Event-driven message processing: Adopt an event-driven approach to respond to events such as connection opening, message reception, connection closing, etc., to achieve an asynchronous and non-blocking communication mode.

4. Flexible configuration options: Provides a wealth of configuration options to facilitate developers to customize behaviors according to project needs. Such as: setting timeout, SSL/TLS encryption options, custom headers, etc.

5. High performance: Supports asynchronous programming model, can effectively utilize system resources, and supports handling a large number of concurrent connections.

02 How to use

1. Install dependent libraries

Install-Package WebSocketSharp -Pre

2. Client

using System;
 using WebSocketSharp;
  
 namespace Example
 {
   public class Program
   {
     public static void Main (string[] args)
     {
       //Create a WebSocket instance and specify its URL
       using (var ws = new WebSocket ("ws:///Laputa"))
       {
         //Add an event handler for the OnMessage event of the ws object
          += (sender, e) =>
                            ("Laputa says: " + );
  
         // Establish a connection to the WebSocket server.
          ();
  
         //Send string to WebSocket server.
          ("BALUS");

          (true);
       }
     }
   }
 }

3. Server

 ("/Laputa");
  
       // Start the WebSocket server
        ();

        (true);
  
       // Stop the WebSocket server.
        ();
     }
   }
 }
