.Netコンソールアプリケーションからpowershellを呼び出す

Question

コンソールからpowershellスクリプトを呼び出したコンソールアプリケーションを作成しました。 PowerShellスクリプトでは、hello worldを戻り変数として書きましたが、期待通りに実行されていますが、次回は文字列をhello worldに変更するとどのように変更された文字列を表示していませんか？私はパイプラインやキャッシュをクリアするために何をする必要があるのか​​自分自身を理解することはできません。 私は、デフォルトの名前空間から離れ

using System.Management; 
using System.Management.Automation; 
using System.Collections.ObjectModel; 
using System.Management.Automation.Runspaces; 



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(); 
    } 

PowerShellのスクリプトすなわちTest1.ps1

ここ

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

      using (Runspace myRunSpace = RunspaceFactory.CreateRunspace()) 
      { 
       myRunSpace.Open(); 
       using (PowerShell powershell = PowerShell.Create()) 
       { 
        // Create a pipeline with the Get-Command command. 
        powershell.AddScript("Set-ExecutionPolicy -Scope Process -ExecutionPolicy Unrestricted"); 
        powershell.AddScript(@"C:\Users\you\Desktop\a.ps1"); 
        // add an extra command to transform the script output objects into nicely formatted strings 
        // remove this line to get the actual objects 
        powershell.AddCommand("Out-String"); 
        // execute the script 
        var results = powershell.Invoke(); 
        powershell.Streams.ClearStreams(); 
        powershell.Commands.Clear();  
        // convert the script result into a single string 
        StringBuilder stringBuilder = new StringBuilder(); 
        foreach (PSObject obj in results) 
        { 
         stringBuilder.AppendLine(obj.ToString()); 
        } 
        Console.WriteLine(stringBuilder.ToString()); 
       } 
      } 
     } 
    } 
}

期待どおりに実行されるode

enter code here 
try 
      { 
       if (System.IO.File.Exists(@"c:\disk\op.txt") && (new FileInfo(@"c:\disk\op.txt").Length != 0)) 
       { 
        System.IO.File.Move(@"c:\disk\op.txt", @"c:\disk\Previous_op_" + DateTime.Now.ToString("dd_MM_yyyy hh mm") + ".txt"); 
        log.Info("Previous Output File Successfully Renamed"); 
       } 
       // TODO: Add delete logic here 
       log.Info("Input ActionResult - Server " + Server); 
       log.Info("Input ActionResult - Volume " + Volume); 
       log.Info("Input ActionResult - Size " + size); 
       string userID = "dir\\" + Session["Uname"].ToString(); 
       string userpassword = Session["Upwd"].ToString(); 
       log.Info("username " + userID);    
       StringBuilder stringBuilder = new StringBuilder(); 
       var con = new WSManConnectionInfo();

       Runspace runspace = RunspaceFactory.CreateRunspace(con); 
       runspace.Open(); 
       Pipeline pipeline = runspace.CreatePipeline();     
       pipeline.Commands.AddScript("Set-ExecutionPolicy -Scope Process -ExecutionPolicy Unrestricted");    
       string _str = @"-Server " + Server + " -Volumeletter " + Volume + ": -deltasize " + size + " -Logfile c:\\disk\\op.txt -username " + userID + " -password " + userpassword; 
       log.Info("Parameter string format- " + _str.Substring(0, _str.IndexOf("-password") + 9)); 
       pipeline.Commands.AddScript(@"C:\disk\diskerr.ps1 " + _str.ToString()); 
       pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output); 
       pipeline.Commands.Add("Out-String"); 
       var results = pipeline.Invoke(); 
       runspace.Close(); 
       runspace.Dispose(); 
       foreach (PSObject obj in results) 
       { 
        stringBuilder.AppendLine(obj.ToString()); 
        log.Info("Output from powershell: " + obj.ToString()); 
       } 

       if (System.IO.File.Exists(@"c:\disk\op.txt") && (new FileInfo(@"c:\disk\op.txt").Length != 0)) 
       { 
        fileStream = new FileStream(@"c:\test\op.txt", FileMode.Open, FileAccess.Read); 
        using (var streamReader = new StreamReader(fileStream, Encoding.UTF8)) 
        { 
         _consoleOutput = streamReader.ReadToEnd(); 
        } 
        _output = Regex.Replace(_consoleOutput, @"\r\n?|\n", "<br />"); 
       } 

       return Content(_output);     
      } 

      catch (Exception ex) 
      { 
       log.Info("Error stackTrace inside Input ActionResult " + ex.StackTrace.ToString()); 
       log.Info("Error Message inside Input ActionResult " + ex.Message.ToString()); 
       return View(); 
      } 

ディレクトリパスとpowershellファイル名を変更する必要があります。
