在 C# 中运行 PowerShell cmdlet

Question

我需要在 Visual Studio 控制台中使用 C# 运行 powershell cmdlet。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Management.Automation;
using System.Threading;
using System.Management.Automation.Runspaces;
using System.Collections.ObjectModel;
using System.Collections;

namespace ConsoleApp1
{
    class Program
    {
        private static string RunScript()
        {

            Runspace runSpace = RunspaceFactory.CreateRunspace();
            runSpace.Open();
            Pipeline pipeline = runSpace.CreatePipeline();
            Command cmd = new Command("Connect-MsolService"); 
            pipeline.Commands.Add(cmd);
            ICollection results = pipeline.Invoke();  // Here exception occurs
            runSpace.Close();
            StringBuilder stringBuilder = new StringBuilder();
            foreach (PSObject obj in results)
            {
                stringBuilder.AppendLine(obj.ToString());
            }

            return stringBuilder.ToString();
        }




        static void Main(string[] args)
        {
            using (PowerShell PowerShellInstance = PowerShell.Create())
            {
                Console.WriteLine(RunScript());
                Console.ReadKey();
            }
        }
    }
}

当我运行代码时发生异常：

“Connect-MsolService”一词未被识别为 cmdlet、函数、脚本文件或可运行程序的名称。检查名称的拼写，或者如果包含路径，请验证路径是否正确并重试。

即使当我在 Powershell 中运行命令时它仍然有效。

Answer 1

尝试使用 PowerShell 实例，如下所示：

InitialSessionState iss = InitialSessionState.CreateDefault();
iss.ImportPSModule(new[] { "MSOnline" });
iss.LanguageMode = PSLanguageMode.FullLanguage;
var _o365Runspace = RunspaceFactory.CreateRunspace(iss);
_o365Runspace.Open();
var _o365Shell = PowerShell.Create();
_o365Shell.Runspace = _o365Runspace;
var connect = new Command("Connect-MsolService");
connect.Parameters.Add("Credential", new PSCredential("logon@name",
        GetSecureString("Password"));
_o365Shell.Commands.AddCommand(connect);
// add some msol commands to _o365Shell.Commands as well
_o365Shell.Invoke();

您将其作为 CMD 命令执行，而不是作为 powershell 命令执行。 您必须在 Powershell 实例上执行它。 检查executing-powershell-scripts-from-c。
