Question

运行以下代码导致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

我刚刚在我的控制台应用程序中尝试了这段代码，但它确实有效：

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" });
        }
    }
}

我猜您的应用程序是 Windows应用程序，并且根本不支持此方案，或者您仍然需要一个控制台窗口（我还没有尝试过这种方式）。

编辑：

它也适用于WinForm应用程序。但是控制台主机仍然需要控制台窗口。要使控制台窗口可用，只需将项目输出类型更改为控制台应用程序。

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。我在实践中从未见过这种情况的使用，甚至不知道它确实有效。它有一些实用的应用吗？
