In C #, how do I customize events?

Wason (zhuhai)

Only one instance is used to describe how to use custom events in C.

Write a class that contains the Custom Event onSendMsg.

File Name: ChatServer. cs

public class ChatServer

{

public delegate void MyEventHandler(string msg);

public event MyEventHandler onSendMsg;

public void SendMsg()

{

OnSendMsg ("start sending messages! ");

}

}

File Name: Form1.cs

///////////////////////////////////

// The code for handling class events is as follows:

private void SendMsgTest()

{

// Create a ChatServer instance

Server f_Server;

f_Server = new Server();

f_Server.onSendMsg += new Server.MyEventHandler(this.OnSendMsg);

// Call the SendMsg () function of f_Server

f_Server.SendMsg();

}

// Process the onSendMsg Event code

protected void OnSendMsg(string msg)

{

// Output debugging information

Console.WriteLine(msg);

}
