Overloading is the act of creating two or more methods with the same name, but that differ in the number and/or type of parameters.
Properties appear to clients to be members, but appear to the designer of the class to be methods. This allows the designer to modify how the property retrieves its value without breaking the semantics of the client program.
Properties include get
and
set
accessors that are used to
retrieve and modify a member field, respectively. The set
accessor has an implicit parameter
named value that represents the value to be assigned through the
property.
When you “pass by reference,” the called method affects the
object referred to in the calling method. When you pass by value,
the changes in the called method are not reflected in the calling
method. You can pass value types by reference by using either the
ref
or the out
keyword.
The out
parameter
eliminates the requirement to initialize a variable before passing
it to a method.
