C# 枚举常用工具方法

        /// <summary>
        /// 获取枚举成员描述信息及名称
        /// 返回:IDictionary
        /// Value:描述信息
        /// Key:值
        /// </summary>
        /// <typeparam name="T">struct类型</typeparam>
        /// <returns>IDictionary</returns>
        protected IDictionary<string, string> GetEnumMemberList<T>() where T : struct
        {
            var members = typeof(T).GetMembers().Where(s => s.MemberType == System.Reflection.MemberTypes.Field);

            Dictionary<string, string> dict = new Dictionary<string, string>();

            foreach (var member in members)
            {
                var attrs = member.GetCustomAttributes(typeof(DescriptionAttribute), false);

                if (!attrs.Any())
                {
                    continue;
                }

                var memberinfo = attrs[0] as DescriptionAttribute;

                if (memberinfo != null)
                {
                    dict.Add(member.Name, memberinfo.Description);
                }
            }

            return dict;
        }

        /// <summary>

        protected List<SelectListItem> Execute(int selectId)
        {

            var list = new List<SelectListItem>();
            foreach (var info in dict)
            {
                int value = (int)Enum.Parse(typeof(SharedScope), info.Key);
                list.Add(
                    new SelectListItem
                    {
                        Value = value.ToString(),
                        Text = info.Value,
                        Selected = value == selectId
                    });
            }

            this.ViewData["Execute"] = list;
            return list;
        }

上面代码是一个泛型的操作枚举的C#语言实现的工具类方法。
