Title Body

I'm trying to get the name of a method on a type using a lambda expression. I'm using Windows Identity Foundation and need to define access policies with the type name with namespace as a resource and the method name as the action. Here is an example. This is the type I would be getting the type name and method name from: namespace My.OrderEntry { public class Order { public void AddItem(string itemNumber, int quantity) {} } } This is how I would like to define the access policy through a DSL: ForResource<Order>().Performing(o => o.AddItem).AllowUsersHaving(new Claim()); From that statement, I would like to get "My.OrderEntry.Order" as the resource and "AddItem" as the action. Getting the type name with namespace is no problem, but I don't think I can use a lambda for a method like I'm trying to do. public static IPermissionExp Performing<T>( this IActionExp<T> exp, Func<T, delegate???> action) {} //this is where I don't know what to define Is this sort of thing even possible to do? Is there another way to do this sort of thing without using magic strings?
