System.Func<DateTime> f1 = () => DateTime.Now.AddDays(12345); System.Linq.Expressions.Expression<System.Func<DateTime>> f2 = () => DateTime.Now.AddDays(12345); Edit: The two answers below by Mika...
First off let me say I am maintaining someone else's poorly designed code so I am limited in how much I can change it. Now what is happening is that they have created a series of methods that are invoked by reflection. One of those methods takes a Map as one of its arguments.

Basically, I have classes that look like this - [MyAttr("CODE")] public class MyClass() {} From there I'm getting all the classes (Types) - var c = Assembly.GetExecutingAssembly().GetTypes().Where (...
I am attempting to create a generic mapping function that takes the values of a dictionary and its sub classes and maps them to the fields in T using reflection. Within object T, there are sub objects that must be drilled into, and through recursion, it seems like a pretty simple concept. However I am stuck -- and I'm not sure if it's ...

The main question I have is: Is it possible in reflection to distinguish a field of some delegate type from a field which is used by an event as storagefield? That comes down to the question: does the FieldInfo class contain information about whether it belongs to an event, as storagefield ? I can't find any properties which might tell...
I was reading over at the android dev website about using reflections. But I'm really not grasping how to use it. I need this java file to run on a 1.5(SDK3) device but just ignore the new code and work fine on a 2.0(SDK5) and up phone. I have this Activity (posted below) and it's a simple webview. However, I want to have geolocation ena...
