Answer / kumaresh
1.Hashtable is a class which falls into System.Collections
namespace.
you can create object for hashtable. For example,
Hashtable hash = new Hashtable();
2.Key and value should be added to hashtable. For example,
hash.Add(1,"God");
hash.Add(2,"Human");
3.The key, value will be sorted automatically based on the
Hashcode generated[this operation is taken care by CLR].
4.GetHashCode() method is used to get the generated hashcode
5.While retrieving the hashtable values, you can use the
key tp retrieve the values. For example
foreach (DictionaryEntry item in hashTable)
{
Console.WriteLine("Key is {0}, Value is
{1}", item.Key,item.Value);
}
NOTE: if you add the same key into the hastable, it will
not throw any compliation error, but during runtime, it
will throw "ArgumentException" error.

Answer / arun yadav
A hash table, or a hash map, is a data structure that
associates keys with values. The primary operation it
supports efficiently is a lookup: given a key (e.g. a
person's name), find the corresponding value (e.g. that
person's telephone number). It works by transforming the
key using a hash function into a hash, a number that is
used as an index in an array to locate the desired location
("bucket") where the values should be.
