C#构造函数、静态构造函数、析构函数的用法

using System;
class Test2
   {
      static int i;
      static Test2() { // a constructor for the entire class called 
                       //once before the first object created
              i = 4;
         Console.Out.WriteLine("inside static construtor...");
      }
      public Test2() {
         Console.Out.WriteLine("inside regular construtor... i={0}",i);
      }
      ~Test2() { // destructor (hopefully) called for each object
       Console.Out.WriteLine("inside destructor");
      }
      
      static void Main(string[] args)
      {
         Console.Out.WriteLine("Test2");
         new Test2();
         new Test2();
      }
   }

输出结果

inside static construtor...
Test2
inside regular construtor... i=4
inside regular construtor... i=4
inside destructor
inside destructor
