// Structures and enumerations extend System.ValueType.

public abstract class ValueType : object

{

public virtual bool Equals(object obj);



public virtual int GetHashCode();

public Type GetType();

public virtual string ToString();

}

Given the fact that value types are using value-based semantics, the lifetime of a structure



(which includes all numerical data types [int, float, etc.], as well as any enum or custom structure)

is very predictable. When a structure variable falls out of the defining scope, it is removed from

memory immediately:

// Local structures are popped off

// the stack when a method returns.

static void LocalValueTypes()

{

// Recall! "int" is really a System.Int32 structure.



int i = 0;

// Recall! Point is a structure type.

Point p = new Point();

}
