假设存在如下所述的类X,如何获取非泛型方法的方法信息？下面的代码将引发异常.

using System;

class Program {
    static void Main(string[] args) {
        var mi = Type.GetType("X").GetMethod("Y"); // Ambiguous match found.
        Console.WriteLine(mi.ToString());
    }
}

class X {
    public void Y() {
        Console.WriteLine("I want this one");
    }
    public void Y<T>() {
        Console.WriteLine("Not this one");
    }
}

如何在Powershell中调用自定义类的通用静态方法？

鉴于以下课程:

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

这被编译成一个程序集'Classes.dll'并加载到PowerShell中,如下所示:

Add-Type -Path "Classes.dll"

调用MyMethod方法最简单的方法是什么？

Powershel的仿制药非常令人困惑.要实例化一个简单的列表,你需要用手鼓跳舞:

$type = ("System.Collections.Generic.List"+'`'+"1") -as "Type"
$type= $type.MakeGenericType("System.string" -as "Type")
$o = [Activator]::CreateInstance($type)

但是,如果我需要更复杂的东西<Dictionary<string,List<Foo>>,例如:

或者例如这里: Dictionary<string,List<string>>

$listType = ("System.Collections.Generic.List"+'`'+"1") -as "Type"
$listType = $listType.MakeGenericType("System.string" -as "Type")
$L = [Activator]::CreateInstance($listType)

$dicType = ("System.Collections.Generic.Dictionary"+'`'+"2") -as "Type"

#the next line is problematic
$dicType = $dicType.MakeGenericType( 
     @( ("system.string" -as "Type"), 
        ("System.Collections.Generic.List" as "Type)) # and that's of course wrong
      )

$D = [Activator]::CreateInstance($dicType )
