HI
I have the following enum

public enum Priority : byte 
    {
        A=1,
        B+ = 2,
        B=4,
        C=8,
        D=16,
        E=32
    }

I want to add B+ in the enum but it is giving me error

回答1:

You can add user friendly description for enum like below :

enum MyEnum 
{ 
    [Description("This is black")] 
    Black, 
    [Description("This is white")] 
    White 
}

How about using a valid identifier like B_Plus?

回答3:

Yes. It's giving you an error because your code is wrong. You can't make "B+" an enum value because there's a plus sign. Same reason you can't declare int B+. Use a different name.

回答4:

You won't be able to use + as a name identifier because it's a math operator or string concatenator... it can't be used with enums. Use an alternative syntax, or use an alternative approach. You could consider a state design pattern:
