c# - are ranges possible with enums?

Question

In C#, can you use number ranges in enum types, for example

public enum BookType
{
    Novel = 1,
    Journal = 2,
    Reference = 3,
    TextBook = 4 .. 10
}

EDIT: The reason this is needed is to cast from a number to the enum type, eg:

int iBook = 5
BookType btBook = (BookType)ibook
Debug.Print "Book " + ibook + " is a " btBook

and the expected output is: Book 5 is a TextBook

Answer 1

As others have said, no it isn't possible. It is possible to combine enum values if they are flags:

[Flags]
public enum BookType
{
    Novel = 0,
    Journal = 1 << 0,
    Reference = 1 << 1,
    TextBook1 = 1 << 2,
    TextBook2 = 1 << 3,
    TextBook3 = 1 << 4,
    TextBook4 = 1 << 5,
    TextBook5 = 1 << 6,
    TextBooks1To5 = TextBook1 | TextBook2 | TextBook3 | TextBook4 | TextBook5
}
