Powershell ConsoleShell.Start出現問題

Question

運行以下代碼導致HostException;

Public Sub RunPowershellInConsole(ByVal scriptText As String) 
    Dim config = RunspaceConfiguration.Create 
    Dim args() As String = New String() {scriptText} 

    ConsoleShell.Start(config, "Windows PowerShell", "", args) 
    End Sub 

。

System.Management.Automation.Host.HostException was unhandled 
    Message=The Win32 internal error "The handle is invalid" 0x6 occurred when retrieving handle for active console output buffer. Contact Microsoft Support Services.

對別人沒有幫助嗎？

我剛纔想這個代碼在我控制檯應用程序和它的工作：

using System.Management.Automation.Runspaces; 
using Microsoft.PowerShell; 

namespace TryConsoleShell 
{ 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      var config = RunspaceConfiguration.Create(); 
      ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" }); 
     } 
    } 
} 

我猜你的應用程序是Windows應用程序這種情況要麼是根本不支持或你還是得有一個控制檯窗口可用（我還沒有嘗試過這種方式）。

編輯：

它也在WinForm應用程序中工作。但控制檯主機仍然需要控制檯窗口。要使控制檯窗口可用，只需將項目輸出類型更改爲控制檯應用程序。

using System; 
using System.Management.Automation.Runspaces; 
using System.Windows.Forms; 
using Microsoft.PowerShell; 

namespace WindowsFormsApplication1 
{ 
    public partial class Form1 : Form 
    { 
     public Form1() 
     { 
      InitializeComponent(); 
     } 

     private void button1_Click(object sender, EventArgs e) 
     { 
      var config = RunspaceConfiguration.Create(); 
      ConsoleShell.Start(config, "Windows PowerShell", "help text", new string[] { "-noexit", "ls" }); 
     } 
    } 
} 

P.S.我從來沒有在實踐中看到過使用這個場景，甚至都不知道它實際上有效。它有一些實際有用的應用程序嗎？
