.Net Reflection

I found this useful tips on Reflection.

Reflection allows you to discover an object’s type at runtime if you don’t already know it and query the structure of the classes. You can also invoke methods, change properties, and play with events all dynamically at runtime.

It’s great for creating a plug-in architecture as well as creating a generic business object validator or a generic data access layer. It’s also handy for hacking a DLL if you don’t have the source code.

Reflection is a fairly advanced topic and assumes good foundational knowledge of object oriented programming
