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usercontext下执行。
我尝试了不同的方案，有些人正在努力工作：
1。来自PowerShell的直接电话
我直接从ps-console调用脚本，该控制台在正确的用户凭据下运行。
C:\Scripts\GroupNewGroup.ps1 1
结果：成功运行脚本。
2。来自c＃控制台应用程序
我从c＃consoleapplication调用了脚本，该脚本是在正确的用户凭据下启动的。
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“Null-Array”例外。
第3。来自c＃控制台应用程序 - 代码端冒充
（http://platinumdogs.me/2008/10/30/net-c-impersonation-with-network-credentials）
我从c＃consoleapplication调用了脚本，该脚本在正确的用户凭据下启动，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：
http://XXXX/websites/Test4/。验证你

映射到预期的应用程序。“到目前为止还没有正常工作的答案
有谁知道为什么存在差异以及如何解决问题？
答案 0 :(得分：8)
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");
}
}

答案 1 :(得分：5)
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来实现它的工作
invoker.Invoke("Set-ExecutionPolicy Unrestricted -Scope Process");
答案 2 :(得分：0)
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/
以下是如何创建包含您要使用的用户名和密码的Credential对象：
$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密码后，您可以执行许多操作，例如调用Start-Process启动PowerShell.exe，在-Credential参数中指定凭据，或调用Invoke-Command在本地调用“远程”命令specifying the credential in the -Credential parameter，或者您可以调用Start-Job来完成后台工作passing the credentials you want into the -Credential parameter。
