ArrayList in Visual Basic

Collections are used to add/delete elements presented like and array but size may vary. So in collections size of the array get changed automatically when we add or delete any element. ArrayList is one of the simplest collections that .NET provides.

Example

Module Module1

    Sub Main()

        Dim DynamicList As New ArrayList()

        DynamicList.Add("first")
        DynamicList.Add("Second")
        DynamicList.Add("Third")

        ' retreiving list
        For Each a In DynamicList
            Console.WriteLine(a)
        Next

        DynamicList.RemoveAt(1) ' removing element at index 1

        Console.WriteLine("------------after deleting second element----------")

        For Each a In DynamicList
            Console.WriteLine(a)
        Next

        Console.ReadLine()

    End Sub

End Module

Output

Second
Third
