SiteMap | About. How to C# Dictionary A Dictionary class is a data structure that represents a collection of keys and values pair of data. The key is identical in a key-value pair and it can have at most one value in the dictionary, but a value can be associated with many different keys.
I am using a C# dictionary. Dictionary d = new Dictionary(); I am using the dictionary as then I can have the key value be unique and is enforced by the Dictionary. The key value will be int. Before I had the need of only one value. Now things have expanded to where I need to store multiple values(with different data types) for the same key.
