从 C# 运行 PowerShell 脚本 [英] Run a PowerShell script from C#

问题描述

我正在尝试使用 Visual Studio 构建图形平台.而且我不是开发人员，我想在单击按钮时运行 PowerShell 或批处理文件.问题是当我尝试 C# 语法时，即使我安装了 PowerShell 扩展，它也不起作用.

I'm trying to build a graphic platform using Visual Studio. And I'm not a developer, I want to run PowerShell or batch files when I click a button. Thing is when I'm trying C# syntax it does not work even if I installed PowerShell extension.

我尝试了一些在 Internet 上找到的代码，使用 process.start 或尝试在所有情况下创建命令，但命令的名称未定义且不起作用.

I tried some code that I found on the internet, using process.start or trying to create a command in all cases the name of the command is not defined and it does not work.

private void Button1_Click(object sender, EventArgs e)
{
    Process.Start("path\to\Powershell.exe",@"""ScriptwithArguments.ps1"" ""arg1"" ""arg2""");
}

我想启动我的 .ps1 脚本，但出现错误

I want to launch my .ps1 script but I get an error

未定义名称进程

推荐答案

在 Powershell 中调用 C# 代码，反之亦然

Powershell 中的 C#

$MyCode = @"
public class Calc
{
    public int Add(int a,int b)
    {
        return a+b;
    }

    public int Mul(int a,int b)
    {
        return a*b;
    }
    public static float Divide(int a,int b)
    {
        return a/b;
    }
}
"@

Add-Type -TypeDefinition $CalcInstance
$CalcInstance = New-Object -TypeName Calc
$CalcInstance.Add(20,30)

C# 中的 Powershell

Powershell 相关的所有功能都在System.Management.Automation 命名空间，...在您的项目中引用该名称

All the Powershell related functions are sitting in System.Management.Automation namespace, ... reference that in your project

 static void Main(string[] args)
        {
            var script = "Get-Process | select -Property @{N='Name';E={$_.Name}},@{N='CPU';E={$_.CPU}}";

            var powerShell = PowerShell.Create().AddScript(script);

            foreach (dynamic item in powerShell.Invoke().ToList())
            {
                //check if the CPU usage is greater than 10
                if (item.CPU > 10)
                {
                    Console.WriteLine("The process greater than 10 CPU counts is : " + item.Name);
                }
            }

            Console.Read();
        }

因此，您的查询实际上也是 stackoverflow 上许多类似帖子的重复.

So, your query is also really a duplicate of many similar posts on stackoverflow.
