如何在 WinUI 3 中从 C# 调用 Powershell 函数

我正在尝试调用 PowerShell 脚本文件中的函数。我在用WinUI 3。我在调试器输出中得到难以理解的输出，并且 PowerShell 脚本似乎根本没有执行。我已验证当我直接从 PowerShell 运行 PowerShell 脚本（或直接在 Visual Studio 中启动它）时，PowerShell 脚本可以正确运行。

下面的C#代码用于调用该函数Setup-Workspaces在 PowerShell 脚本中。请注意，数据类型workspace.Name is string。这是基于在这里回答 https://stackoverflow.com/questions/4179351/calling-powershell-functions-from-c-sharp.

/// <summary>
/// Launches the given workspace using the given powershell script.
/// </summary>
/// <param name="script"></param>
/// <param name="workspace"></param>
internal static void LaunchWorkspace(string script, Workspace workspace)
{
    using (PowerShell powerShell = PowerShell.Create())
    {
        // Add the script to run from.
        powerShell.AddScript(script, false);

        powerShell.Invoke();

        powerShell.Commands.Clear();

        // Add the command in the script to run.
        powerShell.AddCommand("Setup-Workspaces").AddParameter("WorkspaceName", workspace.Name);

        // Execute the command from the script.
        var results = powerShell.Invoke();
        //System.Diagnostics.Debug.WriteLine("Stuff happened");
        //System.Diagnostics.Debug.WriteLine("THE SCRIPT\n\n\n");
    }
}

以下是从 PowerShell 脚本调用的函数。请注意，编写该函数时只需要提供两个参数之一。我已经验证了在独立于 C# 代码运行此脚本时该方法有效。

function Setup-Workspaces {
    # Define the parameter.
    param (
        $Workspaces, $WorkspaceName
    )

    Write-Host ("Setup-Workspaces called... ")

    # ... rest of function here
}

The Write-Host输出永远不会出现在调试器输出窗口中...所以我认为这意味着该函数根本没有运行。

我在调试器窗口中得到的输出（省略了大部分内容，它们是一堆“LOADED”语句：
