将Powershell变量传递到PS脚本中的C#代码 [英] passing powershell variables to C# code within PS script

问题描述

我读了很多有关将var从C#传递到powershell脚本的信息，但是我对另一种方式很感兴趣.

I read a lot about passing vars from C# to powershell script but i am interesten in the other way around.

在这里，我有以下代码在Powershell脚本中创建Type:

here I have this code to create a Type in my powershell script:

Add-Type @'

public class Node
{

    public string Type;
    public string VM_Name;
    public string VM_IP;
    public string Hostname;

}
'@

$vm1 = New-Object Node
$vm2 = New-Object Node
$vm3 = New-Object Node
$vm4 = New-Object Node

此代码后，我有C#代码:

After this code I have C# code:

$sourceCode = @'


public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void InitializeComponent()
    {
    }
}

'@

如何使用上面的C#代码访问$ vm1,2,3,4?

How I might be able to access $vm1,2,3,4 in the C# code above ?

推荐答案

您可以通过C#类中的一种将变量作为参数接受的方法，将变量传递给类型，例如:

You could either pass the variables into the type via a method in your C# class that would accept the variables as parameters e.g.:

$form = new-object Form1
$form.SetVariables($vm1, $vm2, $vm3, $vm4)

我推荐这种方法.

另一种选择(较重且未经测试)是尝试从C#代码访问当前运行空间，例如:

Another option (heavier weight and not tested) is to try accessing the current runspace from the C# code e.g.:

var defRunspace = System.Management.Automation.Runspaces.Runspace.DefaultRunspace;
var pipeline = defRunspace.CreateNestedPipeline();
pipeline.Commands.AddScript("$vm1,$vm2,$vm3,$vm4");
var results = pipeline.Invoke();
var vm1 = results[0];
var vm2 = results[1];
...

我还没有从C#代码中尝试过此操作(仅在PowerShell中)，所以我不是100％确信它会工作.

I haven't tried this from C# code (only from within PowerShell) so I'm not 100% sure it will work.
