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

我尝试过不同的场景，有些可以，有些不行:

<强>1。从 PowerShell 直接调用

我直接从在正确的用户凭据下运行的 ps 控制台调用脚本。

C:\Scripts\GroupNewGroup.ps1 1

结果:成功运行脚本。

<强>2。来自 C# 控制台应用程序

我已经从在正确的用户凭据下启动的 c# 控制台应用程序调用了脚本。

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。

<强>3。来自 C# 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 C# 控制台应用程序调用脚本，该应用程序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 的名称， 函数、脚本文件或可运行的程序。检查拼写 名称，或者如果包含路径，请验证路径是否正确，并且 再试一次。
• 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。查看 名称的拼写，或者如果包含路径，请验证 路径正确，然后重试。
• 尚未为 Windows PowerShell 版本 2 注册任何管理单元。 Microsoft.Office.Server，版本=14.0.0.0，文化=中性， PublicKeyToken=71e9bce111e9429c
• System.DirectoryServices.AccountManagement，版本=4.0.0.0， 文化=中性，PublicKeyToken=b77a5c561934e089
• 使用“1”个参数调用“.ctor”的异常:“Web 应用程序 在 http://XXXX/websites/Test4/ 找不到。验证你 已正确键入 URL。如果 URL 应该服务于现有的 内容，系统管理员可能需要添加新的请求URL 映射到预期的应用程序。”
• 您不能在空值表达式上调用方法。无法索引 进入空数组。

到目前为止还没有有效的答案

有谁知道为什么会有差异以及如何解决问题？

最佳答案

您是否尝试过 Set-ExecutionPolicy Unrestricted

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