使用 Process.Start 启动 PowerShell 脚本会关闭 PowerShell 且没有错误

Question

I'm writing a small app in C# that calls various PowerShell scripts to configure a computer.

I'm having an issue now that I don't think I was having just a couple weeks back when I worked on it last.

When I call these scripts from C# a PowerShell window opens extremely briefly and then closes. I thought perhaps there was an error in my PS script, but no- if I do a Start-Transcript at the beginning I still get no output, so it's clearly not even starting to run my scripts.

My code:

Process.Start(@"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe ", @"C:\Thunder\Scripts\3-BitLockerEnable.ps1");

I thought maybe Execution Policy was the problem, but it's set to unrestricted. I made sure the file path was right- simply removing the PowerShell call lets me check, and it opens the ps1 file in Notepad fine without that line.

Any help appreciated, I'm not sure where I've made a mistake. I could have sworn this exact code was working fine a couple weeks ago. Thanks.

Use the built in PowerShell object:

PowerShell ps = PowerShell.Create();
ps.AddScript(File.ReadAllText(@"C:\Thunder\Scripts\3-BitLockerEnable.ps1")).Invoke();
