Generic Property in Visual Basic .NET

Last Updated: March 19, 2020

You can define generic property in a VB.NET class as shown in below code

Public Class List(Of type)
    Private items() As type
    Private index As Integer

    Public Sub New(ByVal size As Integer)
        ReDim items(size - 1)
        index = 0
    End Sub

    Public Sub Add(ByVal item As type)
        items(index) = item
        index += 1

    End Sub

    Public ReadOnly Property Item(index As Integer) As type
            Return items(index)
        End Get

    End Property

End Class

In Line 16, I have created a read only property as generic type

You can create instance of Integer type using following code

Module Module1

    Sub Main()
        Dim myList As New List(Of Integer)(2)
    End Sub

End Module
