How to Get the parent Class name from a Func?

Question

Lets say I have a func, like the below one...

Func<ISession, IIncomingPacket, IControllerContext, Task>

How would I get the class that the func method belongs to?

If you mean you have a func instance and you want to tell which class method it is referencing to? `func.Method.DeclaringType` ? — Sriram Sakthivel, Apr 08 '18 at 19:05
clicking F12 will move you the actual class of the function. — Abdul Qayyum, Apr 08 '18 at 19:06
What if you have an anonymous method that does not have any class it belongs to? — MakePeaceGreatAgain, Apr 08 '18 at 19:23

Func already has information about the declaring type: myFunc.Method.DeclaringType- see Get MethodInfo for a lambda expression. Note so that really it is useless in most cases as frequently such function will be declared inline at the point of call - you may have to walk up through classes to find something useful.

Func<int, string> f = (i => i.ToString());
Console.Write(f.Method.DeclaringType.Name);

You can't get such information from Func<...> and really it is useless in most cases as frequently such function will be declared inline at the point of call.

Usually to get that information you'd use Expression<...> instead - see How to get Method Name of Generic Func<T> passed into Method for an example.
