对象创建在内存中的引用
创建一个对象,他在堆内存中还是在栈内存中
Person p =new Person(“张三”,20);
这样的,我可不可以这样理解new Person(“张三”,20)在堆内存中创建,分配内存地址。
Person p 在栈内存中创建,然后把堆内存中的内存地址付给栈内存中的p变量
Common common = new Common { Name = "张三" }; Service service = new Service(common); //都是 指向李四 common.Name = "李四"; //service.dao = new Dao(common); //还是 李四 unbelieveable common = null; common = new Common { Name = "王五" }; Console.ReadLine(); public class Common { public string Name { get; set; } } public class Service { public Common _com; public Dao dao; public Service(Common comm ) { this._com = comm; this.dao = new Dao(comm); } } public class Dao { public Common _com; public Dao(Common comm) { this._com = comm; } }
