Running Command Line from C# without Window and Getting Output [duplicate]

Answer 1

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();
}

Answer 2

You are using StartInfo incorrectly. Have a look at documentation for ProcessStartInfo Class and Process.Start Method (). Your code should look something like this:

string ipAddress;
System.Diagnostics.Process p = new System.Diagnostics.Process();
p.StartInfo.UseShellExecute = false;
p.StartInfo.RedirectStandardOutput = true;
string strCmdText;
strCmdText = "/C tracert -d " + ipAdress;

// Correct way to launch a process with arguments
p.StartInfo.FileName="CMD.exe";
p.StartInfo.Arguments=strCmdText;
p.Start();


string output = p.StandardOutput.ReadToEnd();
p.WaitForExit();

Also, note that I added /C argument to strCmdText. As per cmd /? help:

/C Carries out the command specified by string and then terminates.
