在C＃中执行Powershell脚本 [英] Executing powershell scripts in c#

问题描述

下面是我用来尝试执行Powershell脚本的脚本，但是每当我运行它时，我都会得到一个空白的命令窗口。

Below is the script I am using to try and execute my powershell script but whenever i run it i just get a blank command window.

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

Powershell Script

 $text = "test test test"

我要做的就是将测试输出到命令窗口。

All I want to do is output test to the command window.

推荐答案

您可以使用Write-Output代替Write-主办。从winform应用程序调用时，它对我有用。

You can use Write-Output instead of Write-Host. It works for me while invoking from winform application.
