从C＃运行Powershell

Question

I need to start a powershell script from C# and get the PSSSecurityException on pipeline.Invoke()

AuthorizationManager check failed.

My code:

RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();
using (Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration))
{
    runspace.Open();
    Pipeline pipeline = runspace.CreatePipeline();
    Command scriptCommand = new Command(scriptfile);
    pipeline.Commands.Add(scriptCommand);
    pipeline.Invoke();
}

Questions

1. I suspect that I need to set PSCredential. But I can not promt for it, so I have to handle this in code. Can this be done in a secure way? ( This was not the case )

Check out this SuperUser post: https://superuser.com/questions/106360/how-to-enable-execution-of-powershell-scripts

You probably just need to allow unsigned scripts to run. In the PS console, type the following:

set-executionpolicy remotesigned

Another resource echoes this: http://tgnp.me/2011/09/powershell-authorizationmanager-check-failed-resolution/

Give that a try and let me know what happens.

To capture the output from the script, try this:

Collection output = pipeline.Invoke();
foreach (PSObject psObject in output)
{
    <here you can ToString the psObject for the output and write it line by line to your log>
}

Answer 2

The problem was that the script was placed on a share. To run scripts on this share I needed to add the share to Trusted Sites.
