Boxing Occurrence in C#

Question

I\'m trying to collect all of the situations in which boxing occurs in C#:

• Converting value type to System.Object type:

  struct          
  
  
          

Answer 1

• Using the non-generic collections in System.Collections such as ArrayList or HashTable.

Granted these are specific instances of your first case, but they can be hidden gotchas. It's amazing the amount of code I still come across today that use these instead of List and Dictionary.
