Use more effective objects and set Initialization

This suggestion should be known or used by many people. If you do not know it, you will be out. List <Person> list = new List <Person> (); Person p = new Person (); p. ID = 1; p. name = "Tommy"; list. add (p); Sao Nian, are you still doing object and set initialization like this? With the help of the advanced. NET syntax, we can use the object and set initialization tool to write more elegant code. Set the attribute value in braces List <Person> lst = new List <Person> () {new Person () {ID = 1, Name = "Tommy "}, new Person () {ID = 2, Name = "Sammy"}; except for the convenience of object and set initialization, it is also convenient to initialize attributes for the anonymous type during the Linq query. Copy the code List <Person> lst = new List <Person> () {new Person () {Age = 10, Name = "Tommy"}, new Person () {Age = 20, Name = "Sammy" }}; var entity = from p in lst select new {p. name, Agoda = p. age> 10? "Old": "Young"}; foreach (var item in entity) {Response. write (string. format ("name is {0}, {1}", item. name, item. agoda);} copying the Agoda attribute of the Code is calculated. With this convenient initialization method, the code is more elegant and flexible.
