NetworkStream.Read（）不工作，並拋出ArgumentOutOfRangeException

Question

只是想創建一個聊天服務器 - 客戶端

1. 這是等待客戶端連接服務器（可選）*

   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"); 
   

2. 然後，客戶端連接到服務器（可選）*

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

3. 然後，鄰n中的客戶端，我從Windows窗體發送消息，以及按鈕單擊事件做到這一點：

   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(); 
   

4. 最後，在服務器端，客戶端請求無限bucle。而這裏是我上了networkStream.Read（）

   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()); 
        } 
       } 
   

我調試一步一步（服務器和客戶端）的問題，這一切都正常，直到我到達networkStream.Read（ ）方法，並引發ArgumentOutOfRangeException ...請有人幫助我或告訴我錯誤在哪裏。

* I說可選的，因爲1和2的步驟是細（至少，我認爲）

Answer 1

從MSDN，ArgumentOutOfRangeException意味着偏移或計數是否定的（第二和第三參數），或者「size（count）」參數大於緩衝區的長度減去「offset」參數的值。

我想嘗試通過bytesFrom.Length而不是clientSocket.ReceiveBufferSize。
