c# - 从 C# 应用程序运行 PowerShell 脚本

Question

我正在尝试从 ac# 应用程序执行 PowerShell 脚本。该脚本必须在特殊的用户上下文下执行。

我尝试了不同的场景，有些可行，有些不行：

1. PowerShell直接调用

我直接从在正确用户凭据下运行的 ps-console 调用了该脚本。

C:\Scripts\GroupNewGroup.ps1 1

结果：成功运行脚本。

2.来自ac#控制台应用程序

我从 ac# consoleapplication 调用了脚本，该脚本在正确的用户凭据下启动。

代码：

 string cmdArg = "C:\\Scripts\\GroupNewGroup.ps1 1"
 Runspace runspace = RunspaceFactory.CreateRunspace();
 runspace.ApartmentState = System.Threading.ApartmentState.STA;
 runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;


     runspace.Open();

 Pipeline pipeline = runspace.CreatePipeline();

 pipeline.Commands.AddScript(cmdArg);
 pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
 Collection<PSObject> results = pipeline.Invoke();
 var error = pipeline.Error.ReadToEnd();
 runspace.Close();

 if (error.Count >= 1)
 {
     string errors = "";
     foreach (var Error in error)
     {
         errors = errors + " " + Error.ToString();
     }
 }

结果：没有成功。还有很多“空数组”异常。

3. 来自 ac# 控制台应用程序 - 代码端模拟

（http://platinumdogs.me/2008/10/30/net-c-impersonation-with-network-credentials）

我从 ac# consoleapplication 调用了脚本，该脚本在正确的用户凭据下启动，并且代码包含模拟。

代码：

using (new Impersonator("Administrator2", "domain", "testPW"))

                   {
  using (RunspaceInvoke invoker = new RunspaceInvoke()) 
{ 
    invoker.Invoke("Set-ExecutionPolicy Unrestricted"); 
} 

     string cmdArg = "C:\\Scripts\\GroupNewGroup.ps1 1";
     Runspace runspace = RunspaceFactory.CreateRunspace();
     runspace.ApartmentState = System.Threading.ApartmentState.STA;
     runspace.ThreadOptions = PSThreadOptions.UseCurrentThread;


         runspace.Open();

     Pipeline pipeline = runspace.CreatePipeline();

     pipeline.Commands.AddScript(cmdArg);
     pipeline.Commands[0].MergeMyResults(PipelineResultTypes.Error, PipelineResultTypes.Output);
     Collection<PSObject> results = pipeline.Invoke();
     var error = pipeline.Error.ReadToEnd();
     runspace.Close();

     if (error.Count >= 1)
     {
         string errors = "";
         foreach (var Error in error)
         {
             errors = errors + " " + Error.ToString();
         }
     }
 }

结果：

术语“Get-Contact”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。
术语“C:\Scripts\FunctionsObjects.ps1”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。
没有为 Windows PowerShell 版本 2 注册任何管理单元。Microsoft.Office.Server，版本=14.0.0.0，Culture=neutral，PublicKeyToken=71e9bce111e9429c
System.DirectoryServices.AccountManagement，版本=4.0.0.0，文化=中性，PublicKeyToken=b77a5c561934e089
使用“1”参数调用“.ctor”的异常：“http://XXXX/websites/Test4/找不到 Web 应用程序。请验证您是否正确键入了 URL。如果 URL 应该提供现有内容，系统管理员可能需要添加映射到预期应用程序的新请求 URL。”
您不能在空值表达式上调用方法。无法索引到空数组。

直到现在还没有有效的答案

有谁知道为什么存在差异以及如何解决问题？

你有没有尝试过Set-ExecutionPolicy Unrestricted

using ( new Impersonator( "myUsername", "myDomainname", "myPassword" ) ) 
{ 
    using (RunspaceInvoke invoker = new RunspaceInvoke()) 
    { 
        invoker.Invoke("Set-ExecutionPolicy Unrestricted"); 
    } 
}

我只是花了一天时间为自己解决这个问题。

我终于能够通过将-Scope Process添加到 Set-ExecutionPolicy来使其工作

invoker.Invoke("Set-ExecutionPolicy Unrestricted -Scope Process");

Several PowerShell cmddlets take a PSCredential object to run using a particular user account. 可以看看这篇文章 - http://letitknow.wordpress.com/2011/06/20/run-powershell-script-using-another-account/

以下是创建包含要使用的用户名和密码的 Credential 对象的方法：

$username = 'domain\user'
$password = 'something'
$cred = New-Object System.Management.Automation.PSCredential -ArgumentList @($username,(ConvertTo-SecureString -String $password -AsPlainText -Force))

准备好在凭证对象中使用的密码后，您可以执行许多操作，例如调用 Start-Process 以启动 PowerShell.exe、在 -Credential 参数中指定凭证，或调用 Invoke-Command 以调用“ remote" 命令在本地，specifying the credential in the -Credential parameter或者您可以调用 Start-Job 作为后台作业来完成工作，passing the credentials you want into the -Credential parameter.
