调用从C＃PowerShell函数 [英] Calling Powershell functions from C#

问题描述

我有在它的多个PowerShell函数一个PS1文件。我需要创建一个静态的DLL读取内存中的所有功能和定义。然后它调用这些功能之一时，用户呼叫该DLL并传递函数名以及该函数的参数。

I have a PS1 file with multiple Powershell functions in it. I need to create a static DLL that reads all the functions and their definitions in memory. It then invokes one of these functions when a user calls the DLL and passes in the function name as well as the parameters for the function.

我的问题是，是否有可能做到这一点。即调用已被读取并存储在存储器中的功能？

My question is, is it possible to do this. ie call a function that has been read and stored in memory?

推荐答案

有可能的，并且在一个以上的方式。这里可能是最简单的一种。

It is possible and in more than one ways. Here is probably the simplest one.

由于我们的职能是在 MyFunctions.ps1 脚本（只是一个用于此演示）：

Given our functions are in the MyFunctions.ps1 script (just one for this demo):

# MyFunctions.ps1 contains one or more functions

function Test-Me($param1, $param2)
{
    "Hello from Test-Me with $param1, $param2"
}

然后使用下面的代码。这是PowerShell的，但它是从字面上翻译到C＃（你应该做的）：

Then use the code below. It is in PowerShell but it is literally translatable to C# (you should do that):

# create the engine
$ps = [System.Management.Automation.PowerShell]::Create()

# "dot-source my functions"
$null = $ps.AddScript(". .\MyFunctions.ps1", $false)
$ps.Invoke()

# clear the commands
$ps.Commands.Clear()

# call one of that functions
$null = $ps.AddCommand('Test-Me').AddParameter('param1', 42).AddParameter('param2', 'foo')
$results = $ps.Invoke()

# just in case, check for errors
$ps.Streams.Error

# process $results (just output in this demo)
$results

输出：

Hello from Test-Me with 42, foo
