How can enum assign regex "any number" (See description)?

Question

Regular Expressions

public enum Types{
SomeChar = 'D',
Number = ..//нужно чтобы Number соответствовал любому(!) целому/дробному числу
}

Answer 1

In enums, only integer values ​​( byte , sbyte , short , ushort , int , uint , long , and ulong ) or char are allowed .
Alternatively, one of the values ​​of an enumeration element may mean that this value must match any number. But to do this, you need to write code that can correctly interpret such a value.
Instead of enums, you can use constants ( const ) or readonlyvariables. In the latter case, the possibilities for using various data types are not limited, unlike constants. You still have to write the code for verification.

Answer 2

In enum - no way.

Answer 3

Alexei Nemiro absolutely rightly noted that

In enums, only integer values ​​(byte, sbyte, short, ushort, int, uint, long, and ulong) or char are allowed.

But you can cheat by creating a structure or class containing a set of string constants (this doesn’t make much sense for the compiler, but it’s very convenient for code readability and subsequent support):

struct STRING_ENUMERATION
{
    public const string ENUM_A = "Это строка перечисления";
    public const string ENUM_B = "Это другая строка перечисления";
}

class Program
{
    static void Main(string[] args)
    {
        string myVar = STRING_ENUMERATION.ENUM_A;
    }
}
