client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage), client);其中ReceiveMessage是回調函數，我想讓ReceiveMessage傳參數該怎么辦client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage（ar,label1）), client);會報錯，能傳參數嗎

AsyncCallback委托只接受一個 System.IAsyncResult 類型的參數。
如果需要傳遞參數我一般會直接寫匿名函數，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; // 怎么寫都可以 }, client);} |
