ps1 cannot be loaded because running scripts is disabled on this system

Question

I try to run powershell script from c#.

First i set the ExecutionPolicy to Unrestricted and the script is running now from PowerShell ISE.

Now this is c# my code:

class Program {     private static PowerShell ps;     static void Main(string[] args)     {         ps = PowerShell.Create();         string ps1File = Path.Combine(Environment.CurrentDirectory, "script.ps1");         ExecuteScript(ps1File);         Console.ReadLine();     }      static void ExecuteScript(string script)     {         try         {             ps.AddScript(script);             Collection<PSObject> results = ps.Invoke();             Console.WriteLine("Output:");             foreach (var psObject in results)             {                 Console.WriteLine(psObject);             }             Console.WriteLine("Non-terminating errors:");             foreach (ErrorRecord err in ps.Streams.Error)             {                 Console.WriteLine(err.ToString());             }         }         catch (RuntimeException ex)         {             Console.WriteLine("Terminating error:");             Console.WriteLine(ex.Message);         }     } } 

And the output is:

ps1 cannot be loaded because running scripts is disabled on this system. For more informationm see about_Execution_Policies at http://go.microsoft.com/fwlink/?LinkID=135170.

Answer 1

This could be due to the current user having an undefined ExecutionPolicy.

You could try the following:

Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
