How to execute a PowerShell script using C#

I need to execute a PowerShell script using C#:

ProcessStartInfo startInfo = new ProcessStartInfo();

startInfo.FileName = @"cmd.exe";
startInfo.Arguments = @"powershell -File ""C:\Users\user1\Desktop\power.ps1""";
startInfo.Verb = "runas";
startInfo.RedirectStandardOutput = true;
startInfo.RedirectStandardError = true;
startInfo.UseShellExecute = false;
startInfo.CreateNoWindow = true;

Process process = new Process();
process.StartInfo = startInfo;
process.Start();
process.WaitForExit();

This does not work. How can I fix it?

I have a PowerShell script file and sometimes it will have arguments to pass.

None of the answers here helped me but this answer did and was taken from this blog post so credit to the author Duane Newman.

Here's the full code that will run a PowerShell script when you create a console app in Visual Studio that will ByPass any restrictions.

Just change the ps1File variable to your needs below.

// Code taken from: https://duanenewman.net/blog/post/running-powershell-scripts-from-csharp/
// Author: Duane Newman

using System;
using System.Diagnostics;

namespace ConsoleApp
{
    class Program
    {
        static void Main(string[] args)
        {

            InstallViaPowerShell();
        }

       public static void InstallViaPowerShell()
        {

            var ps1File = @"C:\Users\stevehero\source\repos\RGB Animated Cursors PowerShell\RGB Animated Cursors\install-scheme.ps1";

            var startInfo = new ProcessStartInfo()
            {
                FileName = "powershell.exe",
                Arguments = $"-NoProfile -ExecutionPolicy ByPass -File \"{ps1File}\"",
                UseShellExecute = false
            };
            Process.Start(startInfo);

        }
    }
}

In a modern way, you can use System.Management.Automation 7.2.13.

And with the PowerShell class, you can run a PowerShell command or script like below:

PowerShell.Create().AddScript("get-process").Invoke();

Running .ps1 from C# is a really common thing, with many examples all over the web and videos on Youtube showing how/with examples.

Call a Powershell script from c# code

public static int RunPowershellScript(string ps)
{
int errorLevel;
ProcessStartInfo processInfo;
Process process;

processInfo = new ProcessStartInfo("powershell.exe", "-File " + ps);
processInfo.CreateNoWindow = true;
processInfo.UseShellExecute = false;

process = Process.Start(processInfo);
process.WaitForExit();

errorLevel = process.ExitCode;
process.Close();

return errorLevel;
}

As well as see these stackoverflowthreads.

To call a PowerShell script file (example.ps1) from C#

When do we need to set UseShellExecute to True?
