1. Query Operators

.net designer defines a set of extension methods in the class library

A collection of objects to user-friendly operation

These methods constitute extensions of LINQ query operators

This series of extension methods, such as:

Where, Max, Select, Sum, Any, Average, All, Concat, etc.

We are extended for IEnumerable object

That is, as long as the realization of the IEnumerable interface, you can use these extension methods
