源代码如下。使用析构函数就可以调查内存中的学生个数了using System;namespace __2{
class Program
{
static void Main()
{
Student s1 = new Student("王小红");
Student s2 = new Student("周军");
s1 = new Student("Jerry");
}
}
public class Student
{
public static int objects = 0;
public string name;
public Student(string n)
{
name = n;
Console.WriteLine("创建对象个数:{0}"+++objects);
}
~Student()
{
objects --;
Console.WriteLine("创建对象个数:{0}" + objects );
} } }
