C＃中的PowerShell：无法加载DLL wldp.dll

Question

I am getting an error when attempting to run the following in C#.

The error is:

Exception:Thrown Unable to load DLL wldp.dll

PowerShell ps = PowerShell.Create();
ps.AddCommand("Get-BrokerSession");
ps.AddParameter("AdminAddress");
ps.AddParameter("MYSERVERNAMEHERE");
Collection<PSObject> psr = ps.Invoke();

It's also saying that Get-BrokerSession is not a recognized command, yet I can use this at the PS command prompt without issue.

Answer 1

It could be that you have to load the Citrix-specific PowerShell modules. if your PS version is 3.0. this should resolve error: Get-BrokerSession is not a recognized command
then you can move to the next step.

InitialSessionState initial = InitialSessionState.CreateDefault();
initial.ImportPSModule(new string[] { @"C:\Temp\PSModule.psm1" });  // + Include in your PSModule.psm1: function ImportCitrixModule { Asnp Citrix* }
Runspace runspace = RunspaceFactory.CreateRunspace(initial);
initial.ThrowOnRunspaceOpenError = true;
runspace.Open();
RunspaceInvoke runSpaceInvoker = new  RunspaceInvoke(runspace); 
runSpaceInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

PowerShell ps = PowerShell.Create();
ps.Runspace = runspace;
ps.AddCommand("ImportCitrixModule"); // +
Collection<PSObject> psr = ps.Invoke();

According to this blog post it can help to check Prefer 32-bit in the project build settings.

I ran into this error when trying to start an executable file via C# Powershell in a UnitTest project. You cannot select this option for UnitTest projects (so it didn't help me) but running my test without debugging it works as intended. I ended up not having a UnitTest/IntegrationTest...
