How do I use ProcessStartInfo to run a batch file?

Question

But it doesn't work -meaning the java code is not executed. Although the batch file runs fine when clicked in Windows explorer or when run in command line ..

Since this works fine when the batch file is a single DOS command, I think this is somehow related to the fact that the Java code needs ~20 minutes to run. I'm using the following code

var si = new ProcessStartInfo();
si.CreateNoWindow = true;
si.FileName = batchFileName;
si.UseShellExecute = false;
Process.Start(si);

What am I doing wrong?

Set UseShellExecute to true, so it loads cmd.exe to run the batch file.

Or, if you *really* don't want to use ShellExecute, instead run `cmd /C batchFileName.bat`. – Lucas Jones Mar 04 '10 at 21:27
Lucas - how should this be run ? Using ProcessStartInfo or something else? – akapulko2020 Mar 05 '10 at 19:25

You could run "cmd.exe" using ProcessStartInfo, passing "/C batchFileName.bat" as the command line. – Steven Sudit Mar 05 '10 at 21:51
I tried that and doesn't seem to be working for me (I'm not running as Admin and don't have Admin rights. I'm going to try first directly now – Naomi Sep 25 '20 at 14:39

Check this - a batch file wrapper of ProcessStartInfo:

C:\>ProcessStartJS.bat "cmd.exe" -arguments "/c pause" -style Minimized -priority High -newWindow yes -useshellexecute yes

Started: cmd.exe /c pause
PID:6540

As Lucas Jones mentioned in the comments, if you don't want to use ShellExecute, do it like this:

string fullBatPath = @"C:\path with space\file.bat";

var process = new Process()
{
    StartInfo = new ProcessStartInfo
    {
        FileName = "cmd.exe",
        Arguments = $"cmd /C \"{fullBatPath}\"",
        UseShellExecute = false,
        CreateNoWindow = true,
    }
};
process.Start();
