I have a windows service (C#) running as Local System. I want to be able to read my database and run PowerShell commands and scripts. I am able to run most scripts but my test machine is hanging on this one :
NET USE Z: /Delete /y
NET USE Z: \\TEST2\ProgramData
I can run these commands on the computer and it all works but when I try to run these commands from within my Windows Service it hands on the line which runs the script.
private static bool RunPSCommand(string command, out string output)
{
// create Powershell runspace
Runspace runspace = RunspaceFactory.CreateRunspace();
// open it
runspace.Open();
// create a pipeline and feed it the script text
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(command);
// 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
try
{
StringBuilder stringBuilder = new StringBuilder();
Collection<PSObject> results = pipeline.Invoke();
if (pipeline.HadErrors)
{
var errors = pipeline.Error.ReadToEnd();
foreach (object error in errors)
{
stringBuilder.AppendLine(error.ToString());
}
}
// close the runspace
runspace.Close();
// convert the script result into a single string
foreach (PSObject obj in results)
{
stringBuilder.AppendLine(obj.ToString());
}
output = stringBuilder.ToString();
return true;
}
catch (CommandNotFoundException e)
{
output = e.Message;
return false;
}
catch (Exception e)
{
output = e.Message;
return false;
}
}
I am not sure why this is so difficult. I have been wracking my head on this one for three days and trying every option from net use to DOM objects
NET USE Z: /Delete /y
(New-Object -Com WScript.Network).MapNetworkDrive("z:" , "\\test2\programdata")
