The Ultimate Guide to C# WebSocket: Everything You Need to Know

WebSocket is a communication protocol that enables real-time communication between a client and a server. It is designed to be compatible with all modern web browsers and can be used to create web applications that require real-time data transfer. C# is a popular programming language that is used to develop web applications. In this article, we will explore C# WebSocket and how it can be used to create real-time web applications.

What is C# WebSocket?

C# WebSocket is a library that enables developers to create real-time web applications using the WebSocket protocol. It is designed to be easy to use and can be integrated into any C# application. The library provides a simple API that allows developers to send and receive messages over a WebSocket connection.

The WebSocket protocol is a standard protocol for real-time communication between a client and a server. It is designed to be efficient and can be used to create web applications that require real-time data transfer. The protocol is supported by all modern web browsers, making it ideal for creating web applications that can be used by a wide range of users.

How to Use C# WebSocket?

To use C# WebSocket, you need to install the WebSocket library. The library can be downloaded from the NuGet package manager. Once you have installed the library, you can start using it in your C# application.

The library provides a simple API that allows developers to create WebSocket connections, send and receive messages, and close connections. The API is designed to be easy to use and can be integrated into any C# application.

Creating a WebSocket Connection

To create a WebSocket connection, you need to create an instance of the WebSocket class. The WebSocket class provides a constructor that takes a URL as a parameter. The URL should point to the WebSocket server that you want to connect to.

Here is an example of how to create a WebSocket connection:

var ws = new WebSocket(“ws://localhost:8080”);

The above code creates a WebSocket connection to a server running on the local machine on port 8080.

Sending Messages

To send a message over a WebSocket connection, you need to call the Send method of the WebSocket class. The Send method takes a string as a parameter, which is the message that you want to send.

Here is an example of how to send a message over a WebSocket connection:

ws.Send(“Hello World!”);

The above code sends the message “Hello World!” over the WebSocket connection.

Receiving Messages

To receive messages over a WebSocket connection, you need to register an event handler for the OnMessage event of the WebSocket class. The OnMessage event is raised when a message is received over the WebSocket connection.

Here is an example of how to register an event handler for the OnMessage event:

ws.OnMessage += (sender, e) => { Console.WriteLine(e.Data); };

The above code registers an event handler that writes the received message to the console.

Closing Connections

To close a WebSocket connection, you need to call the Close method of the WebSocket class. The Close method takes two parameters: a code and a reason. The code is an integer that represents the reason for closing the connection, and the reason is a string that provides additional information about the reason for closing the connection.

Here is an example of how to close a WebSocket connection:

ws.Close(1000, “Connection closed by client”);

The above code closes the WebSocket connection with a code of 1000 and a reason of “Connection closed by client”.
