Member Field (VB.Net and ASP Classic Cross Reference Guide)

Also known as a Class Field.

A class variable defined with a specific class visibility, usually private visibility. A member property is different than a member field. A member property uses a member field to store values through accessor methods (getters and setters). For example, it is common to use a private member field to store the current value of a property. The current values of all the class member fields is the current state of the object.

What modifiers apply to member fields, if any? Typical member field modifiers include scope modifiers (private, protected, etc.) and read-only. Can you initialize the value of a member field when declared ensuring a default value?

VB.Net:  In VB.Net you can set the visibility of a member field to any visibility: private, protected, public, friend or protected friend. You can intialize a member field with a default when declared. If you set the member field value in your constructor, it will override the default value. Finally, you can use the Shared modifier (no instance required) and ReadOnly modifier (similar to a constant). Syntax Example: Public Class Cyborg   Private FSerialNumber As String = "A100"   Public CyborgName As String   Public CyborgAge As Integer   Public Shared ReadOnly SeriesID As Integer = 100 End Class  VB.Net Member Field

ASP Classic:  ASP Classic does support member fields, but, as usual, you cannot initialize the type nor value of a member field. The type is implied by usage. Syntax Example: Class Cyborg Private FSerialNumber Public FCyborgName Public FCyborgAge Public FSeriesID End Class
