enum

Given a group of about 20 enums that I cannot modify.

Im looking for an elegant solution to generate a random enum from a specific sample (ie, 2, 7, 18)

I could put these into an arraylist, but thought I would ask if there is something else I could try.

Dynamic Type to do away with Reflection

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
