I've been trying to execute my powershell code from a button click on a SharePoint Webpart. I came across this solution on a forum post.
private string RunScript(string scriptText){
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open(); //This is where it errors out.
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(scriptText);
// add an extra command to transform the script
// output objects into nicely formatted strings
// remove this line to get the actual objects
// that the script returns. For example, the script
// "Get-Process" returns a collection
// of System.Diagnostics.Process instances.
pipeline.Commands.Add("Out-String");
// execute the script
Collection<psobject /> results = pipeline.Invoke();
// close the runspace
runspace.Close();
// convert the script result into a single string
StringBuilder stringBuilder = new StringBuilder();
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
return stringBuilder.ToString();}
Run Powershell Script from Sharepoint page
I've added the code from the above post to a Webpart solution but i keep running into the following error on the runspace.Open() line.

I've tried running the code under an impersonation block but that didn't seem to help.
Any ideas/suggestions on fixing this error will be greatly appreciated.
