Build a static delegate from non-static method

Question

I need to create a delegate to a non-static method of a class. The complications is that at the time of creation I don\'t have an intance to the class, only its class defini

Answer 1

You can use Delegate.CreateDelegate to dynamically construct a delegate for a particular target instance given a MethodInfo. You can look up the MethodInfo with Type.GetMethod (Reflection) and cache it for later use creating the delegate.

For example, this would grab the "GetHashCode" method and bind it to the 'this' instance:

        var method = typeof(Object).GetMethod("GetHashCode");
        var del = (Func)Delegate.CreateDelegate(typeof(Func), this, method);

There are more subtleties if you have more than one overload of the method, but there are additional GetMethod parameters you can use to disambiguate, if necessary.
