在調用另一個 powershell 腳本的 c# 中調用 powershell 腳本會引發 UnauthorizedAccessException

Question

下面的功能適用於我的測試

    private static void RunScript(string scriptText)
    {
        Runspace runspace = RunspaceFactory.CreateRunspace();
        runspace.Open();
        Pipeline pipeline = runspace.CreatePipeline();
        pipeline.Commands.AddScript(scriptText);
        pipeline.Commands.Add("Out-String");
        Collection<PSObject> results = pipeline.Invoke();
        runspace.Close();
    }

我這樣稱呼這個函數

RunScript(File.ReadAllText("test.ps1"));

一切都很好。 現在我修改了 test.ps1 來調用其他 powershell 腳本。

但是現在我運行它時出現異常。

UnauthorizedAccessException: cannot be loaded because running scripts is disabled on this system. For more information, see 
about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

我猜我需要將執行策略設置為“繞過”。 我該如何設置？

還有沒有辦法將powershell腳本文件名提供給Pipeline對象而不是腳本文件的內容？

Answer 1

試驗后，確定我可以簡單地多次調用我的函數。 一次設置策略，下次調用任何腳本。 該政策似乎是在一次通話后設置的。

RunScript("Set-ExecutionPolicy -Scope Process -ExecutionPolicy ByPass");
RunScript(File.ReadAllText("test.ps1"));

private static void RunScript(string scriptText)
{
    Runspace runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript(scriptText);
    pipeline.Commands.Add("Out-String");
    Collection<PSObject> results = pipeline.Invoke();
    runspace.Close();
}

您還可以排隊命令，即

private static void RunScript(string scriptText)
{
    Runspace runspace = RunspaceFactory.CreateRunspace();
    runspace.Open();
    Pipeline pipeline = runspace.CreatePipeline();
    pipeline.Commands.AddScript("Set-ExecutionPolicy -Scope Process -ExecutionPolicy ByPass");
    pipeline.Commands.AddScript(scriptText);
    pipeline.Commands.Add("Out-String");
    Collection<PSObject> results = pipeline.Invoke();
    runspace.Close();
}
