反思 - 获取里面的lambda EX pression的方法调用列表 [英] Reflection - Get the list of method calls inside a lambda expression
问题描述
我试图找到一种方式来获得列表的方式调用内部的lambda EX pression在C#3.5。例如,在下面的code,我想方法LookAtThis(行动)来分析的拉姆达EX pression内容。换句话说,我想LookAtThis回到我创建的MethodInfo的对象。
I am trying to find a way to get the list of method calls inside a lambda expression in C# 3.5. For instance, in the code below, I would like to method LookAtThis(Action a) to analyze the content of the lambda expression. In other words, I want LookAtThis to return me the MethodInfo object of Create.
LookAtThis(() => Create(null, 0));
这可能吗?
谢谢!
推荐答案
这是相当容易的,只要你使用防爆pression<作用>
而不是动作
。对于全code,包括如何获得实际值暗示,<一个href="http://$c$c.google.com/p/protobuf-net/source/browse/trunk/protobuf-net.Extensions/ServiceModel/Client/ProtoClientExtensions.cs">see这里 - 尤其是 ResolveMethod
(以及它是如何使用调用
)。这是code我使用protobuf网基于lambda表达式做RPC。
This is fairly easy as long as you use Expression<Action>
instead of Action
. For full code, including how to get the actual values implied, see here - in particular ResolveMethod
(and how it is used by Invoke
). This is the code I use in protobuf-net to do RPC based on lambdas.
