我有一个IInvocation(from Ninject.Extensions.Interception)，.Request.Method它指向我在应用程序中创建的类上的一个方法（因此，自定义，而不是核心 .NET 代码中的任何内容）。当我打电话时invocation.Request.Method.GetMethodBody()，它回来了null。为什么？

using Ninject;
using Ninject.Extensions.Interception;
using Ninject.Extensions.Interception.Infrastructure.Language;

namespace ShortButComplete
{
    class Program
    {
        static void Main(string[] args)
        {
            IKernel kernel = new StandardKernel();
            kernel.Bind<IMethodHolder>().To<MethodHolder>().Intercept().With<MethodReader>();
            var result = kernel.Get<IMethodHolder>().UhOh();
        }
    }

    public class MethodReader : IInterceptor
    {
        public void Intercept(IInvocation invocation)
        {
            var uhoh = invocation.Request.Method.GetMethodBody();
            // The above is null.

            invocation.Proceed();
        }
    }

    public interface IMethodHolder
    {
        int UhOh();
    }

    public class MethodHolder : IMethodHolder
    {
        public int UhOh()
        {
            return 4; // Guaranteed random by roll of a d6.
        }
    }

}

看起来这是一个 Castle DynamicProxy 问题：

using Castle.DynamicProxy;
//using Ninject;
//using Ninject.Extensions.Interception;
//using Ninject.Extensions.Interception.Infrastructure.Language;


//IKernel kernel = new StandardKernel();
//kernel.Bind<IMethodHolder>().To<MethodHolder>().Intercept().With<MethodReader>();
//var result = kernel.Get<IMethodHolder>().UhOh();
var real = new MethodHolder();
var proxy = new ProxyGenerator().CreateInterfaceProxyWithTarget<IMethodHolder>(real, new MethodReader());
var result = proxy.UhOh();

也许方法有一个主体（抽象，接口方法，部分，本机）？
