模块类的解决方法在重写的方法上混乱了

module.ResolveMethod(token, typeArguments, methodArguments)

module.ResolveMethod

class BaseClass
{ public virtual void SomeMethod() {} }

class Derived :BaseClass {}

class MainClass
{
    public static void Main (string[] args)
    {
        Expression<Action<Derived>> expr = (instance) => instance.SomeMethod();
        var method = (expr.Body as MethodCallExpression).Method;
        Console.WriteLine(method.DeclaringType);
    }
}
