.NET Microservices Architecture for Containerized .NET Applications | Lear how you can use enumeration classes, instead of enums, as a way to solve some limitations of the latter.
usingstaticColor;enumColor { Red, Green, Blue }classProgram{publicstaticvoidMain(){ Color color = Green; } } 别名using 创建using别名指令,以便更易于将标识符限定为命名空间或类型。 在任何using指令中,都必须使用完全限定的命名空间或类型,而无需考虑它之前的using指令。using指令的声明中不能使用using别名...

In some cases, the default mechanism for creating files from templates is insufficient. Consider a language that defines multiple types of core entities, e.g., in the Java language, the following entities can be created: Class, Interface, Record, Enum, and Annotation. ...

在这个例子中,我们使用using MyPointer = T*语句定义了一个名为MyPointer的模板类型别名,从而可以使用MyPointer<int>来代替int*类型。 6、using enum 在C++11中,新增了using enum语法,用来为枚举类型定义别名,例如: #include <iostream> enum class Color { RED, GREEN, BLUE }; using ColorType = Color; in...
