Question

只是尝试创建聊天服务器客户端

这是等待客户端连接的服务器（可选）*

    TcpListener serverSocket = new TcpListener(8888);
    int requestCount = 0;
    TcpClient clientSocket = default(TcpClient);
    serverSocket.Start();
    Console.WriteLine(" >> Server Started");
    clientSocket = serverSocket.AcceptTcpClient();
    Console.WriteLine(" >> Accept connection from client");

然后，客户端连接到服务器（可选）*

    System.Net.Sockets.TcpClient clientSocket = new System.Net.Sockets.TcpClient();
    clientSocket.Connect("127.0.0.1", 8888);

然后，在客户端，我从Windows窗体发送消息，按钮单击事件执行此操作：

NetworkStream serverStream = clientSocket.GetStream();
byte[] outStream = System.Text.Encoding.ASCII.GetBytes(textBox2.Text + "$");
serverStream.Write(outStream, 0, outStream.Length);
serverStream.Flush();
//this goes to the server  ------> to the part (4)

//returning from the server <------
byte[] inStream = new byte[10025];
serverStream.Read(inStream, 0, (int)clientSocket.ReceiveBufferSize);
string returndata = System.Text.Encoding.ASCII.GetString(inStream);
textBox2.Text = "";
textBox2.Focus();

最后，在服务器端，客户端请求的无限bucle。这是我在networkStream.Read（）

上遇到问题的地方

while ((true))
    {
        try
        {
            requestCount = requestCount + 1;
            NetworkStream networkStream = clientSocket.GetStream();
            byte[] bytesFrom = new byte[10025];
            if (networkStream.DataAvailable)
            {
                **networkStream.Read(bytesFrom, 0, (int) clientSocket.ReceiveBufferSize);**
                string dataFromClient = System.Text.Encoding.ASCII.GetString(bytesFrom);
                dataFromClient = dataFromClient.Substring(0, dataFromClient.IndexOf("$"));
                Console.WriteLine(" >> Data from client - " + dataFromClient);
                string serverResponse = "Last Message from client" + dataFromClient;
                Byte[] sendBytes = Encoding.ASCII.GetBytes(serverResponse);
                networkStream.Write(sendBytes, 0, sendBytes.Length);
                networkStream.Flush();
                Console.WriteLine(" >> " + serverResponse);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.ToString());
        }
    }

我一步一步地调试（在服务器和客户端上），直到我进入networkStream.Read（）方法并且抛出ArgumentOutOfRangeException ...然后，任何人都帮助我或告诉我错误在哪里。

*我说可选，因为1.和2.步骤很好（至少，我认为）

Answer 1

从MSDN开始，ArgumentOutOfRangeException意味着偏移或计数为负（第2和第3个参数），或者＆＃34;大小（计数）＆＃34;参数大于缓冲区长度减去＆＃34;偏移量＆＃34;参数。

我尝试传递bytesFrom.Length而不是clientSocket.ReceiveBufferSize。

NetworkStream.Read（）不起作用并抛出ArgumentOutOfRangeException
