I have an enum like this
enum Animal:byte
{
Cat=0,
Dog=1,
Horse=2
}
I want to override the ToString() of it to to write a custom string because my application is a multi-language one(Cat.ToString() should retrieve the translated word of cat). so the Description keyowrd can't be used here.can anyone give me a hint to find a neat way to solve this?

I have a boolean isEuropean and based on it's value I want to write
Console.WriteLine("This individual is/is not European");
Is it possible in C# to add a conditional directly inside a string with no additional variables created?
bool isEuropean = true;
Console.WriteLine($"This individual {(isEuropean ? "is" : "is not")} European");
Yes, you can do string interpolation with a ternary, make sure you contain the ternary in parentheses.

You need to apply a string format:

How can I specify new value into system enum?
For example, the LoginFailureAction has a enum that define with microsoft in c# how can I get new value into this enum?
Of course, you can't change the default value of a type. The type is the type, and you can't change it.

I want to add B+ in the enum but it is giving me error
You can add user friendly description for enum like below :
enum MyEnum
{
[Description("This is black")]
Black,
[Description("This is white")]
White
}
Ref. Link : How to have userfriendly names for enumerations?
How about using a valid identifier like B_Plus?
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.
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:
