在c#中执行powershell脚本

下面是我用来尝试执行 powershell 脚本的脚本，但每当我运行它时，我只会得到一个空白的命令窗口。

C# Code

static void Main(string[] args)
{
    string text = System.IO.File.ReadAllText(@"C:\Program Files (x86)\Backup Reporter\Required\edit_website.ps1");

    using (PowerShell PowerShellInstance = PowerShell.Create())
    {
        // use "AddScript" to add the contents of a script file to the end of the execution pipeline.
        // use "AddCommand" to add individual commands/cmdlets to the end of the execution pipeline.
        PowerShellInstance.AddScript(text);

        Collection<PSObject> PSOutput = PowerShellInstance.Invoke();
        foreach (PSObject outputItem in PSOutput)
        {
            // if null object was dumped to the pipeline during the script then a null
            // object may be present here. check for null to prevent potential NRE.
            if (outputItem != null)
            {
                Console.WriteLine(outputItem.BaseObject.ToString() + "\n");
            }
        }
        if (PowerShellInstance.Streams.Error.Count > 0)
        {
            Console.Write("Error");
        }
        Console.ReadKey();
    }
}

Powershell脚本

 $text = "test test test"

我想做的就是将测试输出到命令窗口。

您可以使用 Write-Output 而不是 Write-Host。从 winform 应用程序调用时它对我有用。
