A New Approach To .NET Key Value pairs in Collections
A new approach has been evolved in the Collections ,i.e The LookUp is one the Class in the Collection which represents a collection of keys each mapped to one or more values. We are very familiar with the Dictonary Collection which maps only one value per key mapping.But when we come across to map the keys with more values.Then we have this LookUp Where TKey ----> The types of the keys in the LookUp TValue ----> The type of the elements of each IEnumerable value in the LookUp .
