What are collection objects in VB.net ?
VB.Net implements a special object called Collection object that acts as a container for objects of all types. Collection can hold other objects as well as non object data. A Collection has four methods: - Add: This method adds a member to collection. Along with data one can also specify a key value by which the data can be referenced. - Count: This returns the total number of items in the collection object. - Item: Retrieves an item from the collection. An item can be retrieved either using the index or a key if specified. - Remove: Removes an item from the collection. e.g. Dim students As New Collection students.Add (?john?, ?1?); //The second argument is a key to object students.Add (?paul?, ?2?);
