What are the programming skills of Object Oriented in VB.NET
Editor to share with you what Object Oriented programming skills in VB.NET, I believe most people do not know much, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!
Internal work and heart method 1:
The first thing is to write a basic Class space; just keep in mind the following syntax, and you can take steps. It's off to a good start.
Public Class ClassName'/ /... End Class
The second method of internal work and heart
How to declare Data Member; in Class, but often each Data Member has a different scope of use. That is, Public,Private or Protected have different meanings. For example:
Public stands for properties, where methods and events can be used, including the internal and external services of this Class.
Private properties, methods, and events can only be used within this Class.
The Protected property, methods, and events can only be used on the Derived Class of Inherit.
Public Class ClassName [Public | Private | Protected] Variable As DataType'/ /. End Class
Internal work and heart method 3:
Add methods to Class. The method (Method) can be Sub (the number of non-recursive values) or Function (the number of recursive values); some may even have Arguement, and how many Arguement (serial arguments) depend on the function of this method. So the Prototype of the general method can be as follows:
Public Class ClassName [Public | Private | Protected] [Overloads] [Sub] MethodName (Byval Arguement As DataType,...)'/ /. End Sub End Class Public Class ClassName [Public | Private | Protected] [Overloads] [Function] MethodName (Byval Arguement As DataType,...) As DataType'/ /... Return Value End Function End Class
The Overloads keyword is used to create multiple functions with the same name but different arguments, generally used to reduce the trouble of function naming!
