Use of IDictionary in Asp.net?

The IDictionary class is used for storing collections of key-and-value pairs.

Each element is a key-and-value pair stored in a DictionaryEntry object.

Each association must have a unique key that is not a null reference

for example,

See student,
Key - reg no
Value - name

We can retrive it using key values..
These key values like primary kay in SQL..

            New Dictionary(Of String, String)



        ' Add some elements to the dictionary. There are no 

        ' duplicate keys, but some of the values are duplicates.

        openWith.Add("txt", "notepad.exe")

        openWith.Add("bmp", "paint.exe")

        openWith.Add("dib", "paint.exe")

        openWith.Add("rtf", "wordpad.exe")



        ' The Add method throws an exception if the new key is 

        ' already in the dictionary.

        Try

            openWith.Add("txt", "winword.exe")

        Catch 

            Console.WriteLine("An element with Key = ""txt"" already exists.")

        End Try



End Sub
