Process proc = new Process();
proc.StartInfo.FileName = "ping.exe";
proc.StartInfo.Arguments = "www.sina.com.cn";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.Start();
string output = proc.StandardOutput.ReadToEnd();
//proc.ExitCode返回正确


Process proc = new Process();
proc.StartInfo.FileName = "telnet.exe";
proc.StartInfo.Arguments = "www.sina.com.cn 80";
proc.StartInfo.UseShellExecute = false;
proc.StartInfo.RedirectStandardOutput = true;
proc.Start();
string output = proc.StandardOutput.ReadToEnd();
//proc.ExitCode返回总是－1
