static voID Main(string[] args) {
Hashtable ht = new Hashtable();
ht.Add("001", "Zara Ali");
ht.Add("002", "AbIDa Rehman");
ht.Add("003", "Joe Holzner");
ht.Add("004", "Mausam Benazir Nur");
ht.Add("005", "M. Amlan");
ht.Add("006", "M. Arif");
ht.Add("007", "Ritesh Saikia");
if (ht.ContainsValue("Nuha Ali")) {
Console.Writeline("This student name is already in the List");
} else {
ht.Add("008", "Nuha Ali");
}
// Get a collection of the keys.
ICollection key = ht.Keys;
foreach (string k in key) {
Console.Writeline(k + ": " + ht[k]);
}
