0	HashTable is Old, you should use Dictionary. It is generic and allows you to minimize Boxing. Dictionary<type1,type2> d = new Dictionary<type1,type2>(); d.Add(...) d.Remove(... ) Dictionary is an array of KeyValuePair. www.abhisheksur.com Bhasker, if this helps please login to Mark As Answer. \| Alert Moderator

0	Hashtable comes under System.Collections namespace and is used to store the objects in Key and Value pairs. Below is the code snippet to add and remove the objects from the Hashtable Hashtable hTable = new Hashtable(); hTable.Add("d", "FDASFASD"); // can any type of object hTable.Add("e", 1); // remove the object hTable.Remove("e"); hTable.Remove("DD"); // even if "DD" key doesn't exsits, it will not throw any error Hope this will help you.

Hashtable hTable = new Hashtable();

            hTable.Add("d", "FDASFASD"); // can any type of object

            hTable.Add("e", 1);



            // remove the object

            hTable.Remove("e");

            hTable.Remove("DD"); // even if "DD" key doesn't exsits, it will not throw any error

Hope this will help you.
