Question

In the below code sample, what does {0:X2} mean? This is from the reflection section of the MCTS Application Development Foundation book (covering dynamic code, etc.).

foreach(Byte b in body.GetILAsBodyArray()) { Console.Write('{0:X2}', b); } 

Answer 1

This uses the same format as String.Format(). Check out the following reference:
