C# BeginReceive（）函数?

Question

client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage), client);其中ReceiveMessage是回调函数，我想让ReceiveMessage传参数该怎么办client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage（ar,label1）), client);会报错，能传参数吗

Answer 1

AsyncCallback委托只接受一个 System.IAsyncResult 类型的参数。

如果需要传递参数我一般会直接写匿名函数，比如

12345678910111213

public int Receive(){    byte[] a = null;    int b;    string c;    client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None,    (System.IAsyncResult ar) =>    {        a = c.Split(' ');        b = 100;        // 怎么写都可以    }, client);}
