介绍 enum Days { Saturday=1, Sunday, Monday, Tuesday, Wednesday, Thursday, Friday }; enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 }; 使用 Colors myColors = Colors.Red; string strColor=myColors.tostring(); int IntColor=(int)myColors ;
Colors myColors = Colors.Red | Colors.Blue | Colors.Yellow; 位与 Colors myColors = Colors.Red & Colors.Blue & Colors.Yellow; 遍历 foreach (string s in Enum.GetNames(typeof(Days))) Response.Write(s + "--" + Enum.Parse(typeof(Days), s).ToString()); 转换 Colors mc=Colors Enum.Parse(typeof(Colors ), "red"); if (System.Enum.IsDefined(typeof(Days), "Monday")) Days ds= (Days)Enum.Parse(typeof(Days), "Monday");
public enum NoticeType { Notice = 'A', LabRule = 'H', HotInformation = 'N', Column = 'C', All = '1', Null = '0' } //新建枚举类型 NoticeType noticeType1 = NoticeType.Column; //把枚举类型转换为string d="Column" string d = noticeType1.ToString(); //取得枚举类型的基数 dd='C' char dd = (char)noticeType1; //通过基数取得对应的枚举类型 noticeType2 = NoticeType.Notice //(NoticeType)'A'; 两种方式都可以 NoticeType noticeType2 = (NoticeType)Char.Parse("A"); //通过名称取得枚举类型 noticeType3 = NoticeType.Notice NoticeType noticeType3 = (NoticeType)Enum.Parse(typeof(NoticeType), "Notice");
