hi

T means Type, for example if you want to create a list that has nothing but strings then this is how you do it.

List <string> listname=new List<string>();

if you try to store anything dat of of any other datatype in the list , you will get an exception.

To better understand the subject refer the topics on" Generics".

T stands for type.t can be any class, interface. The type is passed as a parameter at the runtime.

Hi,

It Represents a strongly typed list of objects that can be accessed by index. Provides methods to search, sort, and manipulate lists.

The List(Of T) class is the generic equivalent of the arraylist class. It implements the i list of (T)generic interface using an array whose size is dynamically increased as required.

The List(Of T) class uses both an equality comparer and an ordering comparer.

Thanks
