Using GetType to retrieve Type objects

[KK]

Consider the following code block:
Rectangle r = new Rectangle();
Type t0 = r.GetType()
Type t1 = typeof(System.Drawing.Rectangle);
Type t2 = Type.GetType("System.Drawing.Rectangle");
Type t3 = Type.GetType(r.GetType().ToString());
Console.WriteLine("Results:\nt0: {0}\nt1: {1}\nt2: {2}\nt3: {3}", t0, t1,
t2, t3);
<<<<<

While t0 and t1 print the results one might expect, t2 and t3 return null.
I'm really perplexed by this. If I supply the fully qualified type name,
isn't that enough to uniquely determine the type? Apparently not! My
question is this: given only a string containing fully qualified type name
(e.g. "System.Drawing.Rectangle"), is there a consistent way to get the Type
object that the string corresponds to that will work with most types?

Thanks for any help you can give!

KK... fraid not. You need the assembly name and the fully qualified
name. In a
sense the runtime prepends the assembly name to the fully qualified
name.

Jeff,

I love your OOP tutorial for C#. I've recommended it many times.

I hope you'll add some new sections on v2.0 features someday!

Have you considered writing a book?
