为什么e.AcceptSocket.ReceiveAsync总是如此(Why e.AcceptSocket.ReceiveAsync alway be true)

 我使用SocketAsyncEventArgs构建了一个小的Socket Server端。 但遇到一些问题，当我接受客户端套接字，然后我尝试使用e.AcceptSocket.ReceiveAsync来接收客户端信息，但我不知道为什么它始终显示为我。 这是服务器端： 
 
    private void ProcessAccept(SocketAsyncEventArgs e)
    {
        Console.WriteLine("Process Accept!");
        if (e.BytesTransferred > 0)
        {
            Console.WriteLine("client online...");
        }

        SocketAsyncEventArgs readEventArgs = new SocketAsyncEventArgs();
        readEventArgs.AcceptSocket = e.AcceptSocket;
        readEventArgs.SetBuffer(new byte[1024], 0, 1024);
        readEventArgs.Completed+=readEventArgsIO_Completed;

        Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs);
        if (!willRaiseEvent)
        {
            this.ProcessReceive(readEventArgs);
        }

          this.StartAccept(e);
    }
 
 我的客户端只使用Connect方法连接服务器端并向其发送信息“Hello Server”。 但为什么我在这里总是“真实”？ 
 
Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs);
 
 谢谢。 

I used SocketAsyncEventArgs to build a tiny Socket Server side. but encountering some problems, when I accepted the client socket, then I tried to use e.AcceptSocket.ReceiveAsync to receive client side info, but I don't know why it always show True to me. here is the server side:
 
    private void ProcessAccept(SocketAsyncEventArgs e)
    {
        Console.WriteLine("Process Accept!");
        if (e.BytesTransferred > 0)
        {
            Console.WriteLine("client online...");
        }

        SocketAsyncEventArgs readEventArgs = new SocketAsyncEventArgs();
        readEventArgs.AcceptSocket = e.AcceptSocket;
        readEventArgs.SetBuffer(new byte[1024], 0, 1024);
        readEventArgs.Completed+=readEventArgsIO_Completed;

        Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs);
        if (!willRaiseEvent)
        {
            this.ProcessReceive(readEventArgs);
        }

          this.StartAccept(e);
    }
 
my client side only use the Connect method to connect the server side and send info "Hello Server" to it. but why I am here always got "True"?
 
Boolean willRaiseEvent = e.AcceptSocket.ReceiveAsync(readEventArgs);
 
thx.
