例如:Colors color = (Colors)2 ,那么color即为Colors.Blue 例如:Colors color = (Colors)Enum.ToObject(typeof(Colors), 2),那么color即为Colors.Blue 判断某个整型是否定义在枚举中的方法:Enum.IsDefined 例如:Enum.IsDefined(typeof(Colors), n)) 遍历Enum foreach(varfinEnum.GetValues(typeof(FileSystem...
Array array3 = Enum.GetValues(typeof(Week)); 7、Parse方法:将一个或多个枚举常数的名称或数字值的字符串表示转换成等效的枚举对象。 string s1 = Enum.Parse(typeof(Week), "3").ToString(); int j = Convert.ToInt32(Enum.Parse(typeof(Week), "Wednesday")); ...
Retrieves an array of the values of the underlying type constants in a specified enumeration type. HasFlag(Enum) Determines whether one or more bit fields are set in the current instance. IsDefined(Type, Object) Returns a Boolean telling whether a given integral value, or its name as a ...
value, the returned array includes duplicate values. In this case, calling theGetNamemethod with each value in the returned array does not restore the unique names assigned to members that have duplicate values. To retrieve all the names of enumeration members successfully, call theGetNamesmethod....

The following example uses the Parse(Type, String, Boolean) method to parse an array of strings that are created by calling the GetNames method. It also uses the Parse(Type, String) method to parse an enumeration value that consists of a bit field. C# Copy Run using System; [Flags] ...
