Oddly enough, MSDN has no information on the order preserving properties of data structures. So I've been making the assumption that:

Hashtable and Hashset do not preserve the insertion order (aka the "hash" in there is a giveaway)
Dictionary and List DO preserve the insertion order.

from this I extrapolate that if I have a Dictionary<double,double> foo that defines a curve, foo.Keys.ToList() and foo.Values.ToList() will give me an ordered list of the scope and domain of that curve without messing about with it?

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
