When you pass a value type as a parameter in a method, the value type is copied.A wrapper object is created if you pass a value type to a method that expects an object.Value types are suitable for representing lightweight objects such as vectors, matrices and colors. Value types has less overhead than classes by the fact that no additional memory for the reference is needed. However, there are a few things that are worth mentioning:Structs can’t have a default parameterless constructor. It is provided by default and it initializes all the fields to their default values.You can’t initialize an instance field inside a structYou can’t use inheritance in structsValue types are important for performance since they are allocated on the s…

Blank Visual Studio 2010 Team Explorer Window
