常量的使用

 public class Mall_BusinessSaleTarget : Mall_SetBase
    {


        /// <summary>
        /// IP移动城堡
        /// </summary>
        public const int IP = 0;
        /// <summary>
        ///  暑假尊享卡
        /// </summary>
        public const int Card = 1;
        /// <summary>
        /// 暑期赠票套餐
        /// </summary>
        public const int SummerGivingCard = 2;
        /// <summary>
        /// 暑期绑日卡
        /// </summary>
        public const int SummerDayCard = 3;
        /// <summary>
        /// 手工DIY
        /// </summary>
        public const int DIY = 4;

/// <summary>
/// 指标类型
/// 0 IP移动城堡
/// 1 暑期卡
/// 2 暑期赠票套餐
/// 3 暑期绑日卡
/// 4 手工DIY
/// </summary>
public virtual int TargetType
{

get;
set;
}

　　

　

　类中设置类似上面的常量信息，使用如下：

if(Mall_BusinessSaleTarget.TargetType == Mall_BusinessSaleTarget.SummerDayCard)

{

   //do something...

}
