How to execute .cmd file using C#?

Question

I have a command(.cmd) file with few steps in it. I want to execute this file using a C# code

This is the code I wrote-

Process process = new Process();
ProcessStartInfo startInfo = new ProcessStartInfo();
startInfo.WindowStyle = ProcessWindowStyle.Normal;
startInfo.WorkingDirectory = @"C:\Users\zrana\Desktop\"
startInfo.FileName = @"C:\Users\zrana\Desktop\test.cmd"
process.StartInfo = startInfo;
process.Start();

When I run this program, I get an exception System.ComponentModel.Win32Exception: 'Access is denied'. Is this the right way to do this?

Please read this System.ComponentModel.Win32Exception: Access is denied and this System.ComponentModel.Win32Exception: Access is denied — Rans

I checked the folder and the cmd.exe properties. The permissions look okay. I also tried running the code above in administrator mode. I still get the same error. — Zankhana Rana

You are getting error because your executable doesn't run in Adminstrator mode.
Try to build your project and then from the build output folder right click on the exe and choose "Run as Administrator" if that doesn't help let me know, please.

Update

Please try running your cmd file by calling it from the Windows cmd.exe like this:

var testCmd = @"/C C:\Users\zrana\Desktop\test.cmd";
System.Diagnostics.Process.Start("cmd.exe", testCmd);

I still get the same error. It is in a winforms application that I am trying to run the .cmd file

@ZankhanaRana could you please confirm that the path for the cmd file you are running is correct?

@ZankhanaRana also please try adding manifest file (ex: codeproject.com/Questions/629067/…) like this: <requestedExecutionLevel level="requireAdministrator" uiAccess="false" /> or edit your existing manifest.

I checked and confirmed that the path is correct. And I added a manifest file with the line in the previous comment. I still get the same error.

@ZankhanaRana I've updated the post. Would you please try the updated version?
