如何运行C＃PowerShell脚本

问题描述

我试图运行用C＃PowerShell脚本，但我没有任何成功。这里是我的功能：

I am trying to run a PowerShell script with C#, but I don't have any success. Here is my function:

private void ExecutePowerShellCommand(string scriptfile)
{
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();

    RunspaceInvoke scriptInvoker = new RunspaceInvoke();
    scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

    Pipeline pipeline = runspace.CreatePipeline();

    //Here's how you add a new script with arguments
    Command myCommand = new Command(scriptfile);
    //CommandParameter testParam = new CommandParameter("key", "value");
    //myCommand.Parameters.Add(testParam);

    pipeline.Commands.Add(myCommand);

    // Execute PowerShell script
    pipeline.Invoke();
}

这是我的错误：

访问注册表项HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell'被拒绝。

我怎样才能解决这个问题？我已经看到了假冒的想法，但我似乎没有找到任何很好的例子来冒充。我想运行此脚本作为管理员

How can I solve this issue? I have seen ideas for impersonation, but I didn't seem to find any good examples to impersonate. I would like to run this script as an administrator.

我已经做了如下声明：

[DllImport("advapi32.dll")]
private static extern bool LogonUser(string lpszUsername, string lpszDomain, string lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken);
[DllImport("kernel32.dll")]
private static extern bool CloseHandle(IntPtr handle);

public delegate void IncognitoDelegate(params object[] args);

我已经创建了模拟下列功能：

I have created the following function for impersonation:

public static void Impersonate(IncognitoDelegate incognitoDelegate, params object[] args)
{
    System.IntPtr token = new IntPtr();
    WindowsIdentity wi;
    if (LogonUser("myusername", "", "mypassword", 8, 0, ref token))
    {
        wi = new WindowsIdentity(token);
        WindowsImpersonationContext wic = wi.Impersonate();

        incognitoDelegate(args);

        wic.Undo();
    }
    CloseHandle(token);
}

我创建了作为代表一个功能：

I have created a function which is used as a delegate:

private static void GIncognito(params object[] args)
{
    RunspaceInvoke scriptInvoker = new RunspaceInvoke();
    scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");
}

和我已经修改我的方法：

And I have modified my method:

private void ExecutePowerShellCommand(string scriptfile)
{
    RunspaceConfiguration runspaceConfiguration = RunspaceConfiguration.Create();

    Runspace runspace = RunspaceFactory.CreateRunspace(runspaceConfiguration);
    runspace.Open();

    Impersonate(new Util.IncognitoDelegate(GIncognito));
    //RunspaceInvoke scriptInvoker = new RunspaceInvoke();
    //scriptInvoker.Invoke("Set-ExecutionPolicy Unrestricted");

    Pipeline pipeline = runspace.CreatePipeline();

    //Here's how you add a new script with arguments
    Command myCommand = new Command(scriptfile);
    //CommandParameter testParam = new CommandParameter("key", "value");
    //myCommand.Parameters.Add(testParam);

    pipeline.Commands.Add(myCommand);

    // Execute PowerShell script
    pipeline.Invoke();
}

结果是...

The result was...

...非常SAM错误，告诉我，我不能访问注册表项。

... the very sam error, telling me I can't access registry keys.

推荐答案

默认设置ExecutionPolicy 命令尝试设置计算机范围值。你只需要你的C＃应用​​程序的范围内更改设置，所以你应该添加 -Scope过程选项添加到命令。

The default Set-ExecutionPolicy command attempts to set the machine-wide value. You only want to change the setting within the scope of your C# application, so you should add the -Scope Process option to the command.

使用获取帮助的Set-ExecutionPolicy -detailed 显示以下信息：

注：要更改执行策略默认（LOCALMACHINE）范围，启动Windows PowerShell使用以管理员身份运行选项

...它也描述了 -Scope 选项。

... and it also describes the -Scope option.

这具有的优势 仅 的影响的执行策略脚本从C＃应用程序中运行，它不会不必要地更改默认的PowerShell行为的执行策略。 （所以这是一个安全很多，特别是如果你可以让你的应用程序运行的脚本的有效性的保证。）

This has the advantage of only impacting the execution policy for scripts run from your C# application, and it doesn't unnecessarily change the execution policy for the default PowerShell behavior. (So it's a lot safer, especially if you can make guarantees about the validity of the scripts your application runs.)
