List Methods
The List class is a generic collection and provides all common methods to add, remove, find and replace items in the collection.
Add Items
The Add method adds an item to a List. The following code snippet creates a List and adds items to it by using the Add method.
' Create a list
Dim AuthorList As New List(Of String)()
' Add items using Add method
AuthorList.Add("Mahesh Chand")
AuthorList.Add("Praveen Kumar")
AuthorList.Add("Raj Kumar")
AuthorList.Add("Nipun Tomar")
AuthorList.Add("Dinesh Beniwal")
The AddRange method is used to add a collection of items. The following code snippet adds a collection of items to a List.
Dim authors As String() = {"Mike Gold", "Don Box", "Sundar Lal", "Neel Beniwal"}
AuthorList.AddRange(authors)
Here is complete code to add items to list:
Imports System.Text
