.NET Value Types

There are three types of Value Types:
    1 Built-in
    2 User-defined
    3 Enumerations

Nullable type use:

Nullable<int> p;
int? p;

To determine whether a values has been assigned to the variable or not user p.HasValue.

System.Drawing.Point a user defined value Type.
System.Drawing.Point.Offset is used to move point location.

enum Titles : int { Mr, Ms, Mrs, Dr };
Titles T = Titles.Mr;
T.ToString(); will return “Mr”.

Mind it String Is Not a Value Type.

Important properties of AppDomain: ApplicationIdentity , ApplicationTrust , BaseDirectory , CurrentDomain , DomainManager , DomainDirectory , Evidence , FriendlyName , ID , RelativeSearchPath , SetupInformation , ShadowCopyFiles .
