.Net 콘솔 응용 프로그램에서 powershell 호출

Question

나는 콘솔에서 powershell 스크립트를 호출 한 콘솔 응용 프로그램을 작성했습니다. PowerShell 스크립트에서 hello world를 반환 변수로 작성했으며 예상대로 실행하지만 다음 번에 hello world에서 문자열을 변경하면 어떻게 변경된 문자열이 표시되지 않습니까? 파이프 라인이나 캐시를 지우려면 어떻게해야하는지 스스로 알 수는 없습니다. 나는 기본 네임 스페이스에서 떨어져

static void Main(string[] args) 
     { 
      string _str = string.Empty; 
      _str= RunScript(@"C:\Powershell_Scripts\Test.ps1"); 
Console.WriteLine("Input String is =" + str); 
      Console.Read(); 
} 

private static string RunScript(string scriptText) 
     { 
     // 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("Set-ExecutionPolicy -Scope Process -ExecutionPolicy Unrestricted"); 
     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(); 
     pipeline.Streams.ClearStreams(); 
     // 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(); 
    }

다음

sleep 3 
    $a="" 
    $a = "Hello word" 
    return $a

여기에 ac 예상대로 실행되는 ode

enter code here

디렉토리 경로와 powershell 파일 이름을 변경해야합니다.
