enum conflicts with a previous declaration这个错误信息“enum conflicts with a previous declaration”通常出现在编程中,特别是在C或C++语言中。它意味着你在同一个作用域内两次声明了同一个枚举类型。 为了解决这个问题,你可以: 更改枚举的名称:如果你需要再次声明一个新的枚举,请确保为其选择一个新的名称。 将...

The enum statement allows you to create a strongly typed set of labels. You can use that enumeration in the code without having to parse or check for spelling errors. Enumerations are internally represented as integral value types with a starting value of zero. By default, PowerShell enumeratio...
But since this is optional, it doesn't solve any naming conflicts; it just makes it a little bit more clear.Enum classes have another advantages over old-style enums. You can have a forward declaration to a strongly typed enum, meaning that you can write code like:...

AFAIK, the most common way of dealing with naming conflicts in libraries in C++ is to include the library inside the namespace, and it. However, this isn't a "real" solution in this case: #include<Logic.h>namspace comparator {
For example, you say that there is "no strong precedent from other languages implying a need," but I would argue that this is inherent to the concept of an enum. Having to define each state of the enum twice, and potentially introducing conflicts where two enum values correspond to the sa...
If you are interfacing with a component not written for the .NET Framework, you might be able to determine, either through reflection or from documentation, whether it supports this data type. If it does, you do not need to change anything. If you are interfacing...
