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.
