枚举遍历
public enum EMyType
{
[System.ComponentModel.Description("A类型")]
TypeA = 1,
[System.ComponentModel.Description("B类型")]
TypeB = 1,
[System.ComponentModel.Description("C类型")]
TypeC = 2,
}
接着遍历其枚举名的方法是
[csharp] view plain copy
foreach (var name in Enum.GetNames(typeof(EMyType)))
{
Console.WriteLine(name);
}
接着遍历其枚举名与枚举值的方法是
[csharp] view plain copy
foreach (var value in Enum.GetValues(typeof(EMyType)))
{
Console.WriteLine(string.Format("{0}={1}", value.ToString(), Convert.ToInt32(value)));
}
接着遍历其枚举名，枚举值与描述属性的字符串的方法是
[csharp] view plain copy
foreach (var value in Enum.GetValues(typeof(EMyType)))
{
object[] objAttrs = value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), true);
if (objAttrs != null &&
objAttrs.Length > 0)
{
DescriptionAttribute descAttr = objAttrs[0] as DescriptionAttribute;
Console.WriteLine(string.Format("[{0}]", descAttr.Description));
}
Console.WriteLine(string.Format("{0}={1}", value.ToString(), Convert.ToInt32(value)));
}
枚举反射，根据枚举中的val或者data读取值和描述
举例实用：
1 Type t = Assembly.Load("XXX.SDK").GetType("XXX.SDK.Entities." + ObjType); 2 var dataList = new List<object>(); 3 foreach (var value in Enum.GetValues(t)) 4 { 5 6 object[] objAttrs = value.GetType().GetField(value.ToString()).GetCustomAttributes(typeof(DescriptionAttribute), true); 7 DescriptionAttribute descAttr = objAttrs[0] as DescriptionAttribute; 8 var date = new 9 { 10 Description = descAttr.Description, 11 Name = value.ToString(), 12 value = Convert.ToInt32(value) 13 }; 14 dataList.Add(date); 15 }
根据枚举的名字，读出枚举的描述，内容和值。
UserCardStatus userCardStatu = (UserCardStatus)Enum.Parse(typeof(UserCardStatus), result.user_card_status, true); string txt = GetEnumDescription(userCardStatu); public string GetEnumDescription(Enum enumValue) { string str = enumValue.ToString(); FieldInfo field = enumValue.GetType().GetField(str); object[] objs = field.GetCustomAttributes(typeof(DescriptionAttribute), false); if (objs == null || objs.Length == 0) return str; DescriptionAttribute da = (DescriptionAttribute)objs[0]; return da.Description; }
根据枚举的单个内容，读出描述
