Classes and fields

In VB, classes are used to define objects with specific properties (fields) and behaviors (methods). Here’s an overview of how classes and fields work in VB.

To define a class in VB, use the Class keyword followed by the class’s name. Here’s an example:

Class MyClass
    ' Class members will be defined here
End Class

Fields

Fields, also known as attributes or variables, are the data members of a class. They represent the properties or characteristics of an object. Fields hold data values that are associated with objects created from the class. Fields are declared within the class, typically at the beginning, and can have different access modifiers (Public, Private, Protected, and so on) to control their visibility and accessibility:

Class MyClass
    Private myField As Integer
    Public anotherField As String
End Class

In the preceding example...
