hashtable in asp.net c#

The Hashtable object contains items in key/value pairs. The keys are used as indexes, and very quick searches can be made for values by searching through their keys.

Hashtable hashtable = new Hashtable();
key = 1;
name = "A";
hashtable.Add(key,name);
key = 2;
name = "B";
hashtable.Add(key,name);
key = 3;
name = "lily";
hashtable.Add(key,name);

u can use foreach loop for read 

foreach (string key in hashtable.Keys)   {     
    Response.Write(key + '=' + hashtable[key] + "<br>");   
}
