Examples might be text or json, although it appears sub-protocols aren't a widely-used feature. We also use the thread-safe Interlocked class to increment the websocket counter, and the result is the unique ID of the new websocket we're about to create. In this particular example the ID is only used for output purposes, but in the other WebSocketWithBroadcasts example we'll talk about shortly, it plays a more important role The following example program creates a client that connects to a server. The client is built with a synchronous socket, so execution of the client application is suspended until the server returns a response. The application sends a string to the server and then displays the string returned by the server on the console Once you've opened your connection, you can begin transmitting data to the server. To do this, call the WebSocket object's send () method for each message you want to send: exampleSocket.send(Here's some text that the server is urgently awaiting!); You can send data as a string, Blob, or ArrayBuffer Here are the examples of the csharp api class System.Net.WebSockets.ClientWebSocket.ConnectAsync(System.Uri, System.Threading.CancellationToken) taken from open source projects. By voting up you can indicate which examples are most useful and appropriate When a client connects to a server, it sends a GET request to upgrade the connection to a WebSocket from a simple HTTP request. This is known as handshaking. This sample code can detect a GET from the client. Note that this will block until the first 3 bytes of a message are available
