.NET

I'm reading a comma-delimited list of strings from a config file. I need to check whether another string is in that list. For example:

"apple,banana,cheese"

If I check for "apple" I should find it, but if I check for "app" I should not.

What's the most straight-forward and concise way to do this? It doesn't have to be fast.

(I'll add my solution as an answer, but I'm hoping someone has something better.)

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
