如何将参数从 C# 传递到 PowerShell 脚本文件? [英] How to pass a parameter from C# to a PowerShell script file?

问题描述

从命令行我可以做到.

.\test.ps1 1

从 C# 执行此操作时如何传递参数?我试过了

How do I pass the parameter when doing this from C#? I've tried

   .AddArgument(1)
   .AddParameter("p", 1)

并且我尝试在 .Invoke() 中将值作为 IEnumerable<object> 传递，但 $p 没有得到值.

And I have tried passing values in as IEnumerable<object> in the .Invoke() but $p does not get the value.

namespace ConsoleApplication1
{
    using System;
    using System.Linq;
    using System.Management.Automation;

    class Program
    {
        static void Main()
        {
            // Contents of ps1 file
            //  param($p)
            //  "Hello World ${p}"

            var script = @".\test.ps1";

            PowerShell
                .Create()
                .AddScript(script)
                .Invoke().ToList()
                .ForEach(Console.WriteLine);
        }
    }
}

推荐答案

怎么样?

static void Main()
{
    string script = @"C:\test.ps1 -arg 'hello world!'";
    StringBuilder sb = new StringBuilder();

    PowerShell psExec = PowerShell.Create();
    psExec.AddScript(script);
    psExec.AddCommand("out-string");

    Collection<PSObject> results;
    Collection<ErrorRecord> errors;
    results = psExec.Invoke();
    errors = psExec.Streams.Error.ReadAll();

    if (errors.Count > 0)
    {
        foreach (ErrorRecord error in errors)
        {
            sb.AppendLine(error.ToString());
        }
    }
    else
    {
        foreach (PSObject result in results)
        {
            sb.AppendLine(result.ToString());
        }
    }

    Console.WriteLine(sb.ToString());
}

这是一个类似的版本，它传递一个 DateTime 的实例

Here's a similar version that passes an instance of a DateTime

static void Main()
{
    StringBuilder sb = new StringBuilder();

    PowerShell psExec = PowerShell.Create();
    psExec.AddCommand(@"C:\Users\d92495j\Desktop\test.ps1");
    psExec.AddArgument(DateTime.Now);

    Collection<PSObject> results;
    Collection<ErrorRecord> errors;
    results = psExec.Invoke();
    errors = psExec.Streams.Error.ReadAll();

    if (errors.Count > 0)
    {
        foreach (ErrorRecord error in errors)
        {
            sb.AppendLine(error.ToString());
        }
    }
    else
    {
        foreach (PSObject result in results)
        {
            sb.AppendLine(result.ToString());
        }
    }

    Console.WriteLine(sb.ToString());
}
