Circular definition in a constant enum

Question

I\'m trying to create a constant of type Enum but I get a error.. My enum is:

public enum ActivityStatus
{
    Open = 1,
    Close = 2
}
         


        

Answer 1

Because the c# compiler intepretes the third ActivityStatus in:

public const ActivityStatus ActivityStatus = ActivityStatus.Open; 

as the name of the constant being defined instead than the name of the enumeration - hence the circular reference: you are definining a constant in terms of the constant itself.

In C# you can use the same name for members and types, and usually resolve ambiguities specifying the fully qualified names (i.e. adding the namespace), but in my experience it is not a good idea, it makes code confusing: the compiler can figure out which is which, but the poor human reading the code has an hard time figuring out if a certain name refers to a class or type or member.
