静态代码块(主要是注意执行顺序)

 1  public class MyJingTaiDaimaKuai
 2     {
 3         public static int i = test1();//1.最开始执行
 4         public int age = test2();//new的时候先执行成员变量的初始化，再执行构造函数
 5  
 6         static MyJingTaiDaimaKuai()
 7         {
 8             Console.WriteLine("静态代码块");//2.再执行
 9         }
10         public MyJingTaiDaimaKuai()//4.//6.
11         {
12             Console.WriteLine("构造函数");
13         }
14  
15         public static int test1()
16         {
17             Console.WriteLine("test1");
18             return 3;
19         }
20  
21         public static int test2()//3.//5.
22         {
23             Console.WriteLine("test2");
24  
25             return 333;
26         }
27     }
28  

1 MyJingTaiDaimaKuai a1 = new MyJingTaiDaimaKuai();
2 Console.WriteLine(a1.age);
3  
4 MyJingTaiDaimaKuai a2 = new MyJingTaiDaimaKuai();
5 Console.WriteLine(a2.age);
