c# 用枚举声明属性和字段，防止非法值，枚举 类型转换

 /// <summary>
        /// 性别
        /// </summary>
        public enum Gender
        {
            Male=0, Female=1
        }

        private Gender studentGender;
        public Gender StudentGender
        {
            get { return studentGender; }
            set { studentGender = value; }
        }

 

//将枚举转换成字符串
            Console.WriteLine("性别的值是：{0}",this.StudentGender.ToString());
            //将字符串转换成枚举
            Console.WriteLine("性别的值是：{0}",(Gender)(Enum.Parse(typeof(Gender),"Female")));

默认情况下，第一个枚举符号的值是 0
