Re: Extending System.Drawing.Rectangle...

You'd probably need to wrap the Rectangle inside a new class and internally use the Rectangle to perform standard Rectangle functionality, tgen add what you want.
Of course you wouldn't be able to use the new class *as* a Rectangle where a Rectangle was expected.

In .net 3.0 you *might* be able to use extension methods. ( not 100% sure if you can use them on structs, but worth checking)

What extra functionality are you looking to add?

Subject: [DOTNET-WINFORMS] Extending System.Drawing.Rectangle...

Hi all,

I have a question about extending structs: I'd like extend
System.Drawing.Rectangle such that it keeps all its existing functionality
and a set of new public members can be called. Since Rectangle is a
structure, it's sealed and cannot be derived from, so that route is
obviously out.

I could easily create a simple new class that would have all the
functionality of Rectangle and the extra functions that I want to add, but I
was wondering if doing this to Rectangle itself would even be technically
possible (for example during run time, if necessary.)

Thanks,
Gyorgy Bozoki
