来给反射调用加加速（2）：手写Emit

有个库，人家写好了，呵呵，咱直接调用就行了，具体怎么实现的我不清楚啊。。

 

分享一些我封装好的扩展方法吧，基于MethodInfo的，名叫FastInvoke

 

 

 

public static void FastInvoke(this MethodInfo methodInfo, object target)
        {
            Dynamic<object>.Instance.Procedure.Explicit.CreateDelegate(methodInfo)(target);
        }

        public static void FastInvoke<TArg1>(this MethodInfo methodInfo, object target, TArg1 arg1)
        {
            Dynamic<object>.Instance.Procedure.Explicit<TArg1>.CreateDelegate(methodInfo)(target, arg1);
        }

        public static void FastInvoke<TArg1, TArg2>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2)
        {
            Dynamic<object>.Instance.Procedure.Explicit<TArg1, TArg2>.CreateDelegate(methodInfo)(target, arg1, arg2);
        }

        public static void FastInvoke<TArg1, TArg2, TArg3>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3)
        {
            Dynamic<object>.Instance.Procedure.Explicit<TArg1, TArg2, TArg3>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3);
        }

        public static void FastInvoke<TArg1, TArg2, TArg3, TArg4>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3, TArg4 arg4)
        {
            Dynamic<object>.Instance.Procedure.Explicit<TArg1, TArg2, TArg3, TArg4>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3, arg4);
        }

        public static void FastInvoke<TArg1, TArg2, TArg3, TArg4, TArg5>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3, TArg4 arg4, TArg5 arg5)
        {
            Dynamic<object>.Instance.Procedure.Explicit<TArg1, TArg2, TArg3, TArg4, TArg5>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3, arg4, arg5);
        }

        public static TRet FastInvoke<TRet>(this MethodInfo methodInfo, object target)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit.CreateDelegate(methodInfo)(target);
        }

        public static TRet FastInvoke<TRet, TArg1>(this MethodInfo methodInfo, object target, TArg1 arg1)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit<TArg1>.CreateDelegate(methodInfo)(target, arg1);
        }

        public static TRet FastInvoke<TRet, TArg1, TArg2>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit<TArg1, TArg2>.CreateDelegate(methodInfo)(target, arg1, arg2);
        }

        public static TRet FastInvoke<TRet, TArg1, TArg2, TArg3>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit<TArg1, TArg2, TArg3>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3);
        }

        public static TRet FastInvoke<TRet, TArg1, TArg2, TArg3, TArg4>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3, TArg4 arg4)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit<TArg1, TArg2, TArg3, TArg4>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3, arg4);
        }

        public static TRet FastInvoke<TRet, TArg1, TArg2, TArg3, TArg4, Targ5>(this MethodInfo methodInfo, object target, TArg1 arg1, TArg2 arg2, TArg3 arg3, TArg4 arg4, Targ5 arg5)
        {
            return Dynamic<object>.Instance.Function<TRet>.Explicit<TArg1, TArg2, TArg3, TArg4, Targ5>.CreateDelegate(methodInfo)(target, arg1, arg2, arg3, arg4, arg5);
        }
