使用this 调用另一个构造器

当我们需要使用多个构造器的时候,为了减少代码量,可以使用this来调用自身的构造器

 1 using System;
 2 using System.Collections.Generic;
 3 using System.Linq;
 4 using System.Text;
 5 using System.Threading.Tasks;
 6 
 7 namespace ALTest.Employee
 8 {
 9     class Employee2
10     {
11 
12         public Employee2(string firstName, string lastName)
13         {
14             FirstName = firstName;
15             LastName = lastName;
16         }
17 
18 
19         //  :this (firstName,lastName) 调用了 public Employee2(string firstName, string lastName) 构造器
20         public Employee2(
21             int id,string firstName, string lastName)
22             :this (firstName,lastName)
23         {
24             Id = id;
25         }
26 
27 
28         public int Id { get; set; }
29         public string FirstName { get; private set; }
30         public string LastName { get; private set; }
31         public string  Salary { get; set; }
32         public string Title { get; set; }
33 
34     }
35 }
