How to implement class constructor in Visual Basic?
Solution 1:
Not sure what you mean with "class constructor" but I'd assume you mean one of the ones below.
Instance constructor:
Public Sub New()
End Sub
Shared constructor:
Shared Sub New()
End Sub
Solution 2:
Suppose your class is called MyStudent. Here's how you define your class constructor:
Public Class MyStudent
Public StudentId As Integer
'Here's the class constructor:
Public Sub New(newStudentId As Integer)
StudentId = newStudentId
End Sub
End Class
Here's how you call it:
Dim student As New MyStudent(studentId)
Of course, your class constructor can contain as many or as few arguments as you need--even none, in which case you leave the parentheses empty. You can also have several constructors for the same class, all with different combinations of arguments. These are known as different "signatures" for your class constructor.
