一般使用enum关键词定义枚举类型并指定枚举成员。 enumSeason { Spring, Summer, Autumn, Winter } 默认情况下,枚举成员的关联常数值为类型int,它们从0开始,并按定义文本顺序递增1,可以显式指定任何其他整数数值类型作为枚举类型的基础类型,还可以显示指定关联的常数值。 enumSeason { Spring, Summer, Autumn =1000,...
add functionality to enum type usingextension methods alwaysconsider defining an enumeration member whose value is 0, because the memory used for the enumeration isinitialized to zero by defaultwhen it's created. usingSystem;usingSystem.Linq;// Season Enum, underlyingType is Int32, values is 0,1...
Primitives (int, string, etc...), Enums, Nullable<>, Lazy<> TimeSpan, DateTime, DateTimeOffset Guid, Uri, Version, StringBuilder BigInteger, Complex, Half Array[], Array[,], Array[,,], Array[,,,], ArraySegment<>, BitArray KeyValuePair<,>, Tuple<,...>, ValueTuple<,...> ...
MessagePack for C# is also optimized for String Key. First of all, it do not decode UTF8 byte[] to String for matching with the member name, it will look up the byte[] as it is(avoid decode cost and extra allocation).And It will try to match each long type (per 8 character, if...

Redefine an enum with a new name and all the members mark it with [CodeGenModel("OriginEnumName")].NOTE: because enums can't be partial all values have to be copiedGenerated code before (Generated/Models/Colors.cs): namespace Azure.Service.Models { public enum Colors { Red, Green, ...
Looking at the similar files used by Xcode itself, there are additional capabilities (especially with respect to enum values etc.) over what I have here.Many of the option comments are taken form, or heavily derived from, the equivalent compiler command-line option description in the mcs ‘...
在你的问题中你展示了MessageCategory,但在你谈论的foreach中ContactType,我假设这是一个打字错误。但我会这样做: foreach (var contact in Enum.GetValues(typeof(MessageCategory)).OfType<MessageCategory>().Where(m =>(int)m < 2000 && (int)m >1000)){ Console.WriteLine(contact);} ...
