我可以在StreamReader套接字C＃上收到一個int嗎？

我開發了一個java數據應用程序客戶端通過套接字發送int到C＃中的應用程序服務器，但我不知道我怎麼能收到一個int。因爲如果我把int mensagem = sr.ReadLine（）不工作！

服務器應用程序的C＃中的代碼：

//Some code not include. 

    public void Server() 
    { 

     Socket soc = listener.AcceptSocket(); 
     //Informa uma conecção 
     //MessageBox.Show("Conectado: " + soc.RemoteEndPoint); 

     try 
     { 
      Stream s = new NetworkStream(soc); 
      StreamReader sr = new StreamReader(s); 
      StreamWriter sw = new StreamWriter(s); 
      sw.AutoFlush = true; // enable automatic flushing 

      while (true) 
      { 
       string mensagem = sr.ReadLine(); //if i put int message not work why? 
       comando(mensagem); 
      } 
      //s.Close(); 
     } 
     catch (Exception e) 
     { 
      MessageBox.Show("Erro!" + e.Message); 
     } 
     //MessageBox.Show("Disconectado: " + soc.RemoteEndPoint); 
     //soc.Close(); 

    } //Fim Função Server

ReadLine返回一個字符串。您可以使用的TryParse讓你的整數：從你的問題

int fromClient; 

if (!int.TryParse(mensagem, out fromClient)) 
{ 
    // error parsing as integer 
} 

// fromClient is either the parsed value or 0 if TryParse was false
