I caught myself doing something like this last week. I had what seemed
like a rather thorny problem with very dynamic objects for backing up
C#.NET WPF property grids, and temporarily ended up down the
Reflection.Emit and IDynamicMetaObjectProvider trails (*). A body can
definitely end up not seeing the forest for the trees when doing this
kind of thing, and at one point I ended up with

value = Activator.CreateInstance(typeof(dataType), "");

to get an empty string, when I in fact knew by virtue of having arrived
at that particular switch case that I needed an empty string...otherwise
I wouldn't have been calling the constructor form that accepted a string
parameter. IOW, the switch case for the above was for strings only, and
I knew that 'dataType' had to be a string value.

It struck me all of a sudden, and I ended up with

value = "";

Rule of Thumb: if things have gotten bloody complicated and they don't
feel like they ought to have been that way, you're probably right.

AHS

* I eventually realized that simple dynamic objects did handle the problem.
