此代码为我提供了正确的输出。

This code gives me the correct ouput.

const string ipAddress = "127.0.0.1";
Process process = new Process
{
    StartInfo =
    {
        UseShellExecute = false,
        RedirectStandardOutput = true,
        RedirectStandardError = true,
        CreateNoWindow = true,
        FileName = "cmd.exe",
        Arguments = "/C tracert -d " + ipAddress
    }
};
process.Start();
process.WaitForExit();
if(process.HasExited)
{
    string output = process.StandardOutput.ReadToEnd();
}
