Working with Dictionaries in C#

In .NET, a Dictionary class is a collection of a key and value pair of data. C# represents a generic Dictionary class that can be used to create a collection of objects. The key should be identical in a key-value pair and it can have at most one value in the dictionary. TKey represents the data type used for the dictionary's keys, and TValue represents the data type used to store the information or data associated with a key. This class is defined in the System.Collections.Generic namespace. You should import the System.Collections.Generic namespace in code to use the dictionary.
