從C＃應用程序運行PowerShell腳本

Question

我正在嘗試從ac＃應用程序執行PowerShell腳本。 該腳本必須在特殊的usercontext下執行。

我嘗試了不同的場景，有些人正在努力：

1.來自PowerShell的直接調用

我直接從ps-console調用腳本，該控制台在正確的usercredentials下運行。

C:\Scripts\GroupNewGroup.ps1 1

結果：成功運行腳本。

2.來自ac＃console應用程序

我從ac #consoleapplication調用了腳本，該腳本是在正確的usercredentials下啟動的。

碼：

 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();
     }
 }

結果：沒有成功。 還有很多“Null-Array”例外。

3.來自ac＃console應用程序 - 代碼端冒充

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

我從ac #consoleapplication調用了腳本，該腳本在正確的用戶憑據下啟動，代碼包含模擬。

碼：

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();
         }
     }
 }  

結果：

• 術語“Get-Contact”不被識別為cmdlet，函數，腳本文件或可操作程序的名稱。 檢查名稱的拼寫，或者如果包含路徑，請驗證路徑是否正確，然后重試。
• 術語“C：\\ Scripts \\ FunctionsObjects.ps1”未被識別為cmdlet，函數，腳本文件或可操作程序的名稱。 檢查名稱的拼寫，或者如果包含路徑，請驗證路徑是否正確，然后重試。
• 沒有為Windows PowerShell版本2注冊管理單元.Microsoft.Office.Server，Version = 14.0.0.0，Culture = neutral，PublicKeyToken = 71e9bce111e9429c
• System.DirectoryServices.AccountManagement，Version = 4.0.0.0，Culture = neutral，PublicKeyToken = b77a5c561934e089
• 調用帶有“1”參數的“.ctor”的異常：“無法找到http://XXXX/websites/Test4/的Web應用程序。驗證您是否正確輸入了URL。如果URL應該服務在現有內容中，系統管理員可能需要向目標應用程序添加新的請求URL映射。“
• 您無法在空值表達式上調用方法。 無法索引到空數組。

到目前為止還沒有可行的答案

有誰知道為什么存在差異以及如何解決問題？

Answer 1

您是否嘗試過Set-ExecutionPolicy Unrestricted

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

Answer 2

我只是花了一天時間為自己解決這個問題。

我終於通過將-Scope Process添加到Set-ExecutionPolicy來使其工作

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

Answer 3

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

以下是如何創建包含要使用的用戶名和密碼的Credential對象：

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

准備好在憑證對象中使用密碼后，您可以執行許多操作，例如調用Start-Process以啟動PowerShell.exe，在-Credential參數中指定憑據，或調用Invoke-Command以調用“遠程“命令本地， specifying the credential in the -Credential parameter ，或者您可以調用Start-Job作為后台作業， passing the credentials you want into the -Credential parameter 。
