The Capacity property gets and sets the number of items a list can hold without resizing. Capacity is always greater than or equal to the Count value.
The following code snippet creates a List of authors and displays the original capacity. After that, code removes the excess capacity by calling TrimExcess method. After that, capacity is set to 20.

Imports System.Text

Imports System.IO

Imports System.Collections.Generic

Module Module1

    Sub Main()

        ' Create a list of strings

        Dim AuthorList As New List(Of String)()

        AuthorList.Add("Mahesh Chand")

        AuthorList.Add("Praveen Kumar")

        AuthorList.Add("Raj Kumar")

        AuthorList.Add("Nipun Tomar")

        AuthorList.Add("Dinesh Beniwal")

        ' Original Capacity

        Console.WriteLine("Original Capacity: {0}", AuthorList.Capacity)

        ' Trim excess


        Console.WriteLine("Trimmed Capacity: {0}", AuthorList.Capacity)

        ' Update Capacity

        AuthorList.Capacity = 20


        Console.WriteLine("Updated Capacity: {0}", AuthorList.Capacity)


    End Sub

End Module
