c# - Calling generic static method in PowerShell

Question

How do you call a generic static method of a custom class in Powershell?

Given the following class:

public class Sample
{
    public static string MyMethod<T>( string anArgument )
    {
        return string.Format( "Generic type is {0} with argument {1}", typeof(T), anArgument );
    }
}

And this is compiled into an assembly 'Classes.dll' and loaded into PowerShell like this:

Add-Type -Path "Classes.dll"

What's the easiest way to call the MyMethod method?

Answer 1

The easiest way to call MyMethod is, as @Athari says, to use MakeGenericMethod. Since he doesn't actually show how to do that, here is a verified working code sample:

$obj = New-Object Sample

$obj.GetType().GetMethod("MyMethod").MakeGenericMethod([String]).Invoke($obj, "Test Message")
$obj.GetType().GetMethod("MyMethod").MakeGenericMethod([Double]).Invoke($obj, "Test Message")

with output

Generic type is System.String with argument Test Message
Generic type is System.Double with argument Test Message
