ArrayList in C#.net

             First time, User uses this ArrayList class this error will occur.

Reason: Because user doesn’t declare a namespace for ArrayList.

Solution: Declare Namespace Using System.Collection.

In this Sample Project, I am using enumeration and ArrayList.

 

In this Example, I am creating an enumeration and Call that enumeration into ArrayList and sort that ArrayList.

Some useful Methods in ArrayList:

1. Add
2. AddRange
3. Remove
4. RemoveAt
5. Sort
6. RemoveRange

Add:

   User can add a information into ArrayList Using Add Method.

This is a Simple Example for Add Method.

AddRange:

     Add the elements of an ICollection to the end of the ArrayList.

ICollection:

· It is an Interface. Because it starts with “I”. Generally, “I” is called Interface.

· Defines size, enumerators, and synchronization methods for all nongeneric collections.
