client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage), client);其中ReceiveMessage是回調(diào)函數(shù)，我想讓ReceiveMessage傳參數(shù)該怎么辦client.BeginReceive(buffer, 0, buffer.Length, SocketFlags.None, new AsyncCallback(ReceiveMessage（ar,label1）), client);會(huì)報(bào)錯(cuò)，能傳參數(shù)嗎

TA貢獻(xiàn)1796條經(jīng)驗(yàn) 獲得超7個(gè)贊

AsyncCallback委托只接受一個(gè) System.IAsyncResult 類型的參數(shù)。

如果需要傳遞參數(shù)我一般會(huì)直接寫匿名函數(shù)，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);}
