代码：

 private void button1_Click(object sender, EventArgs e)
        {
            Process p = null;
            p = new Process();
            p.StartInfo.FileName = "cmd";
            p.StartInfo.Arguments = "/K start telnet 192.168.8.101";
            p.StartInfo.UseShellExecute = false;
            p.StartInfo.RedirectStandardInput = true;
            p.StartInfo.RedirectStandardOutput = true;
            p.StartInfo.RedirectStandardError = true;
            p.StartInfo.CreateNoWindow = false;
            p.Start();
            p.OutputDataReceived+=new DataReceivedEventHandler(p_OutputDataReceived);
            SendKeys.Send("123456\r");
            System.Threading.Thread.Sleep(500);
            SendKeys.Send("enable\r");
            System.Threading.Thread.Sleep(500);
            SendKeys.Send("123456\r");
            System.Threading.Thread.Sleep(500);
            SendKeys.Send("configure terminal\r");
            System.Threading.Thread.Sleep(500);
            SendKeys.Send("interface pon 1/1\r");
            System.Threading.Thread.Sleep(500);
            SendKeys.Send("show legal-onu-info\r");
            System.Threading.Thread.Sleep(800);
            
                
            p.BeginOutputReadLine();

              
             p.WaitForExit();
           
             p.Close();
           } 

    private  void p_OutputDataReceived(object Sender, DataReceivedEventArgs e)
        {
            if (e.Data != null)
            {
                
                result = e.Data;
             
            }
           
        }
             

取到的返回值都是空，有木有人用这种方法真正实现过(我主要是想取到最后的那个列表并在窗体里面显示)

[max_min_]

取不到值，说明哪里调用失败了！楼主回头查查代码！检查各个接口的返回值！ 另外c# 可以去.net大板块下有个c#小板块，那里可能有人更专业的回答！

最后用socket写的，主要搞清楚telnet 协议
