C#枚举

Gender.cs

 /// <summary> /// 性别类型 /// </summary> enum Gender {    男,女 }  //枚举是值类型 //枚举中不能定义字段属性和方法 //枚举值是从0递增的整数

Child.cs

 using System; using System.Collections.Generic; using System.Linq; using System.Text;  namespace LeiheDuixiang {     /// <summary>     /// 小朋友     /// </summary>     class Child     {         //隐藏信息，private不能在类外进行访问       private  string name; //字段       private Gender sex = Gender.男;       private int age;          /// <summary>        /// 完成字段的对外访问接口        /// 属性，属性的名字首字母应该大写        /// </summary>       public string Name        {           get { return name; }//读访问器，返回字段的值           set { name = value; } //写访问器，给字段赋值       }        public Gender Sex       {           get { return sex; } //只读       }        public int Age       {           get { return age; }           set{ age = value; }       }        public Child(string name, Gender sex, int age) //形参       {           Name = name;           Age = age;           this.sex = sex;  //this 当前对象，可以访问当前对象的对象，属性，方法       }     } }
