List<int> myList = list. Distinct(). ToList();
A key-value pair consists of two related data elements: A key, which is a constant that defines the data set (e.g., gender, color, price), and a value, which is a variable that belongs to the set (e.g., male/female, green, 100). Fully formed, a key-value pair could look like these: gender = male. color = green.
Answer: A key-value pair (KVP) is a set of two linked data items: a key, which is a unique identifier for some item of data, and the value, which is either the data that is identified or a pointer to the location of that data. Key-value pairs are frequently used in lookup tables, hash tables and configuration files.
Distinct by both Key and Value:
var results = source.Distinct().ToList();
Distinct by Key or Value (just change the property on GroupBy call:
var results = source.GroupBy(x => x.Key).Select(g => g.First()).ToList();
