How to use Dictionary class in Systems.Collections.Generic

Create a Dictionary object and populate it and enumerate it to display key value pairs.

Example if we want to have integer as key and string as value. we can create dictionary object in the following way:

Dictionary<int,string> dictNames =new Dictionary<int,string>();

dicNames.Add(1,”Raj”);

dicNames.Add(3,”Ravi”);

dicNames.Add(5,”Kevin”);

In order to retrieve above value enumerate it i.e use foreach loop
and use KeyValuePair object  as the elements are retrieved as
KeyValuePair objects



foreach(KeyValuePair<int,string> kvpName in dictNames)

Console.WriteLine(kvpName.Key+”  “+kvpName.Value);
