使用相同的方法名称调用多个dll导入

[DllImport("mydll.dll", EntryPoint="MyMethod")]
public static extern int MyMethod();

extern alias MyDll1;
extern alias MyDll2;

using System;

public class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine(MyDll1::MyMethod());
        Console.WriteLine(MyDll2::MyMethod());
    }
}

using System;

namespace MyDll1
{
    public class MyMethod
    {
        public static int MyMethod()
        {
            // ...
        }
    }
}

namespace MyDll2
{
    public class MyMethod
    {
        public static int MyMethod()
        {
            // ...
        }
    }
}
