如何从 C# 运行 PowerShell 脚本

我正在尝试使用 C# 运行 PowerShell 脚本，但没有成功。这是我的功能：

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();
}

这是我得到的错误：

对注册表项“HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell”的访问被拒绝。

我该如何解决这个问题？我见过模仿的想法，但似乎没有找到任何好的模仿例子。我想以管理员身份运行此脚本。

我已作出以下声明：

[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);

我创建了以下模拟函数：

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);
}

我创建了一个用作委托的函数：

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

我修改了我的方法：

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……

...同样的错误，告诉我无法访问注册表项。

这是方法 b，不需要提升权限或注册表修改权.

Using Process.Start启动它并添加相关的首字母-command or -file args.

%SystemRoot%\system32\WindowsPowerShell\v1.0\powershell.exe -执行策略绕过

这是另一种技术，http://dmitrysotnikov.wordpress.com/2008/06/27/powershell-script-in-a-bat-file/ http://dmitrysotnikov.wordpress.com/2008/06/27/powershell-script-in-a-bat-file/

这依赖于首先对其进行编码并通过 int 传递来执行-EncodedCommandpowershell.exe 的 arg，它似乎绕过了执行策略。
