原型模式
1.利用对象拷贝,快速获取对象
学生原型:
public class StudentPrototype { public int Id { get; set; } public string Name { get; set; } public Class Class { get; set; } private StudentPrototype() { } private static StudentPrototype _studentPrototype = new StudentPrototype() { Id = 0, Name = "", Class = new Class() { Id = 0, Name = "" } }; public static StudentPrototype GetStudentPrototype() { return (StudentPrototype) _studentPrototype.MemberwiseClone(); } }
班级类:
public class Class { public int Id { get; set; } public string Name { get; set; } }
代码调用:
class Program { static void Main(string[] args) { StudentPrototype student1 = StudentPrototype.GetStudentPrototype(); student1.Id = 11; student1.Name = "张三"; student1.Class = new Class() { Id = 111, Name = "3年1班", }; Console.WriteLine($"Student Id is {student1.Id },Student Name is {student1.Name},Class Id is {student1.Class.Id},Class Name is {student1.Class.Name}"); StudentPrototype student2 = StudentPrototype.GetStudentPrototype(); student2.Id = 22; student2.Name = "李四"; student2.Class = new Class() { Id = 222, Name = "3年3班", }; Console.WriteLine($"Student Id is {student2.Id },Student Name is {student2.Name} Class Id is {student2.Class.Id},Class Name is {student2.Class.Name}"); } }
