When the property get and set method has been called?

i have the following property开发者_JAVA技巧 declaration

 Public Property IsAreaSelected() As Integer
        Get
            Return If(ViewState("IsAreaSelected") Is Nothing, 0, Cint(ViewState("IsAreaSelected")))
        End Get
        Set(ByVal value As Integer)
            ViewState("IsAreaSelected") = value
        End Set
    End Property

i want to know when this set and get method will be called ?

will it be called when i execute

IsAreaSelected() =0 

or is there anything like

IsAreaSelected().get()

or

IsAreaSelected().set()

??

You call (use) it exactly like a field in your class:

IsAreaSelected = 0 

If AreaSelected > 0 Then ...

Properties are referenced without using parentheses. To reference the property getter, use this syntax:

xxx = AreaSelected

To access the property setter, use this syntax:

AreaSelected = xxx
