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
