问题
I'm trying to execute a PowerShell script from a c# application. The script has to be executed under a special usercontext.
I've tried different scenarios some are working some not:
1. direct call from PowerShell
I've called the script directly from a ps-console which is running under the correct usercredentials.
C:\Scripts\GroupNewGroup.ps1 1
Result: Successfully running the script.
2. from a c# console application
I've called the script from a c# consoleapplication which is started under the correct usercredentials.
Code:
string cmdArg = "C:\\Scripts\\GroupNewGroup.ps1 1"
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.ApartmentState = System.Threading.ApartmentState.STA;
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(cmdArg);
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
Collection<PSObject> results = pipeline.Invoke();
var error = pipeline.Error.ReadToEnd();
runspace.Close();
if (error.Count >= 1)
{
string errors = "";
foreach (var Error in error)
{
errors = errors + " " + Error.ToString();
}
}
Result: No Success. And a lot of "Null-Array" exceptions.
3. from a c# console application - code side impersonating
(http://platinumdogs.me/2008/10/30/net-c-impersonation-with-network-credentials)
I've called the script from a c# consoleapplication which is started under the correct usercredentials and the code contains impersonation.
Code:
using (new Impersonator("Administrator2", "domain", "testPW"))
{
using (RunspaceInvoke invoker = new RunspaceInvoke())
{
invoker.Invoke("Set-ExecutionPolicy Unrestricted");
}
string cmdArg = "C:\\Scripts\\GroupNewGroup.ps1 1";
Runspace runspace = RunspaceFactory.CreateRunspace();
runspace.ApartmentState = System.Threading.ApartmentState.STA;
runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;
runspace.Open();
Pipeline pipeline = runspace.CreatePipeline();
pipeline.Commands.AddScript(cmdArg);
pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
Collection<PSObject> results = pipeline.Invoke();
var error = pipeline.Error.ReadToEnd();
runspace.Close();
if (error.Count >= 1)
{
string errors = "";
foreach (var Error in error)
{
errors = errors + " " + Error.ToString();
}
}
}
Results:
- The term 'Get-Contact' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
- The term 'C:\Scripts\FunctionsObjects.ps1' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
- No snap-ins have been registered for Windows PowerShell version 2. Microsoft.Office.Server, Version=14.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c
- System.DirectoryServices.AccountManagement, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089
- Exception calling ".ctor" with "1" argument(s): "The Web application
at
http://XXXX/websites/Test4/could not be found. Verify that you have typed the URL correctly. If the URL should be serving existing content, the system administrator may need to add a new request URL mapping to the intended application." - You cannot call a method on a null-valued expression. Cannot index into a null array.
Until now there is no working answer
Does anyone know why there are differences and how to solve the problem?
回答1:
Have you tried Set-ExecutionPolicy Unrestricted
using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) )
{
using (RunspaceInvoke invoker = new RunspaceInvoke())
{
invoker.Invoke("Set-ExecutionPolicy Unrestricted");
}
}

回答2:
I just spent the day fixing this for myself.
I finally was able to make it work by adding -Scope Process to Set-ExecutionPolicy
invoker.Invoke("Set-ExecutionPolicy Unrestricted -Scope Process");
回答3:
Several PowerShell cmddlets take a PSCredential object to run using a particular user account. May have a look at this article -
http://letitknow.wordpress.com/2011/06/20/run-powershell-script-using-another-account/
Here's how you can create the Credential object containing the username and password you want to use:
$username = 'domain\user'
$password = 'something'
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))
Once you have the password ready for use in a credential object, you can do a number of things, such as call Start-Process to launch PowerShell.exe, specifying the credential in the -Credential parameter, or Invoke-Command to invoke a "remote" command locally, specifying the credential in the -Credential parameter, or you could call Start-Job to do the work as a background job, passing the credentials you want into the -Credential parameter.
