How can .GetType cause exception?

[Guest]

Hello,

I want to map data to class properties. Looking at a few examples, I see
that calls to .GetType, .GetProperties, etc. are always in try/catch blocks.
Not sure why this is. Are certain permissions required to run routines in
system.reflection?

Thanks,

Bill

Please ignore: Checked further and I see that I need to set the app up with
"full" trust. Thanks.
