将枚举类型转换为int在C#里非常简单,直接(int)强转就行了,可是这样写代码不方便,尤其让我这种懒癌患者难受,我喜欢用扩展方法的方式实现转换(如果不理解扩展方法请自行补课,这里不再介绍),比如这样string转int: publicstaticclassExtendString {publicstaticintToInt(thisstrings,intdefaultValue =0) {inti;returnint.Tr...
EnumToIntConverter可在 C# 中按如下所示方式使用: C# classEnumToIntConverterPage:ContentPage{publicEnumToIntConverterPage(){ Picker picker =newPicker { Title ="EnumToIntConverter"}; picker.SetBinding(Picker.ItemsSourceProperty,nameof(ViewModel.AllStates)); picker.SetBinding(Picker.SelectedItemProperty,na...

Python从Enum类返回int Python中的Enum类是一个枚举类,它用于定义一组具有特定值的常量。当需要使用一组固定的值作为选项时,可以使用Enum类来定义这些选项,以提高代码的可读性和可维护性。 Enum类返回int的方式有两种: 使用枚举成员的value属性:每个枚举成员都可以通过访问其value属性来获取其对应的整数值。例如,如果...
I know that I can useenum class B : unsigned int. But why is the default underlying type ofenumdifferent that the default underlying type ofenum class? There should be a design decision. ClarificationsI forgot to mention the error:
