C # Advanced Programming reading Notes (V): Operators

1, empty merge operator

int NULL ; int 0 ; Console.WriteLine (b);

Output: 0

2, crating and unpacking

Converting a value type to a reference type is called boxing, and converting a reference type back to a value type is called unpacking.

3, comparing the equality of reference types

Three methods: ReferenceEquals () and two versions of Equals (), and comparison operators (= =).

4, operator overloading

C # requires that all operator overloads be declared public and static, which means that they are associated with their class or structure, rather than with a particular instance.
