C#对枚举的常用操作

枚举操作类：

 public partial class XEnumHelper
    {
        /// <summary>
        /// 获得枚举的所有枚举项
        /// </summary>
        /// <param name="enumType"></param>
        /// <returns></returns>
        public static IList<string> GetEnums(Type enumType)
        {
            IList<string> enums = new List<string>();

            foreach (string s in Enum.GetNames(enumType))
            {
                enums.Add(s);
            }

            return enums;
        }

        /// <summary>
        /// 将字符串转换为枚举
        /// </summary>
        /// <param name="enumType">枚举类型</param>
        /// <param name="strValue">字符串值</param>
        /// <returns></returns>
        public static object String2Enum(Type enumType, string strValue)
        {
            return Enum.Parse(enumType, strValue);
        }
    }

枚举定义：

public enum OperateType
        {
            None = 0,
            Add = 1,
            Edit = 2,
            Delete = 3
        }

客户端调用：

 static void Main(string[] args)
        {
            //获取枚举的常数值
            OperateType opreateType = OperateType.Edit;
            int num = (int)opreateType;
            Console.WriteLine("枚举项Edit的常数值为：{0}", num);

            //字符串转换为枚举值
            string optType = "Delete";
            opreateType = (OperateType)XEnumHelper.String2Enum(typeof(OperateType), optType);
            Console.WriteLine("字符串值：{0}转换为枚举类型：{1}", optType, opreateType);

            //通过枚举的常数值获得枚举值
            num = 3;
            opreateType = (OperateType)num;
            Console.WriteLine("枚举项常数值为3对应的枚举项为：{0}", opreateType);

            //列举枚举值
            IList<string> enums = XEnumHelper.GetEnums(typeof(OperateType));
            int loopNo = 0;
            foreach (string e in enums)
            {
                loopNo += 1;
                Console.WriteLine("枚举项{0}:{1}", loopNo, e);
            }

            Console.Read();
        }
