Is it possible to give enums properties?

I know you can give them methods by creating an extension method on another class, but are properties possible as well? The best you can do as far as I know is using an extension method that takes zero parameters.

In case you're wondering why I ask this, I have this enum with some custom attributes:

enum Operator : byte
{
    [Category(OperatorCategory.Multiplicative), Symbol("")      ] None,
    [Category(OperatorCategory.Additive),       Symbol("+")     ] Add,
    [Category(OperatorCategory.Additive),       Symbol("\u2212")] Subtract,
    [Category(OperatorCategory.Multiplicative), Symbol("\u22C5")] Multiply,
    [Category(OperatorCategory.Multiplicative), Symbol("\u00F7")] Divide,
    [Category(OperatorCategory.Exponential),    Symbol("^")     ] Exponent,
    [Category(OperatorCategory.Exponential),    Symbol("\u221A")] Root,
    [Category(OperatorCategory.Exponential),    Symbol("log")   ] Logarithm
}

I want to do a really simple thing: add a .Category property that returns the category of the operator (so I don't have to type the same thing all over again).

Take a look at this article, it might give you some insight into what you want:

Using Enumeration Classes instead of Enum Types

I have not tried this, I just thought it looked relevant. My suggestion was going to be create a class that holds a list of your properties, then the integer based index of the enum, instead of a byte that you used, could be used to retrieve the property value you need based on the enum value.
