如果我们的枚举类型结构如下,我们需要获取enum的name,value以及description

 

public enum EnumTest    {        [Description("Attribute")]        Attribute1 = 1,        [Description("Attribute")]        Attribute2 = 2,        [Description("Measure")]        Measure1 = 3,        [Description("Measure")]        Measure2 = 4    }

获取的函数代码如下:

public class EnumHelper    {        /// 
        /// get all information of enum,include value,name and description        /// 
        /// the type of enumName        /// 
             public static List
     
       GetAllItems(Type enumName)        {            List
      
        list = new List
       
        ();            // get enum fileds            FieldInfo[] fields = enumName.GetFields();            foreach (FieldInfo field in fields)            {                if (!field.FieldType.IsEnum)                {                    continue;                }                // get enum value                int value = (int)enumName.InvokeMember(field.Name, BindingFlags.GetField, null, null, null);                string text = field.Name;                string description = string.Empty;                object[] array = field.GetCustomAttributes(typeof(DescriptionAttribute), false);                if (array.Length > 0)                {                    description = ((DescriptionAttribute)array[0]).Description;                }                else                {                    description = ""; //none description,set empty                }                //add to list                dynamic obj = new ExpandoObject();                obj.Value = value;                obj.Text = text;                obj.Description = description;                list.Add(obj);            }            return list;        }        /// 
        
        /// get enum description by name        /// 
        /// 
        
         enum type
                /// 
        the enum name        /// 
                public static string GetDescriptionByName
        
         (T enumItemName)        {            FieldInfo fi = enumItemName.GetType().GetField(enumItemName.ToString());            DescriptionAttribute[] attributes = (DescriptionAttribute[])fi.GetCustomAttributes(                typeof(DescriptionAttribute), false);            if (attributes != null && attributes.Length > 0)            {                return attributes[0].Description;            }            else            {                return enumItemName.ToString();            }        }    }
