The new operator is used to create new instances of types.
There are three forms of new expressions:
?Object creation expressions are used to create new instances of class
types and value types.
?Array creation expressions are used to create new instances of array types.
?Delegate creation expressions are used to create new instances of delegate
types.
The new operator implies creation of an instance of a type, but does not
necessarily imply dynamic
allocation of memory. In particular, instances of value types require no
additional memory beyond the
variables in which they reside, and no dynamic allocations occur when new
is used to create instances of
value types.
