How can I create an enum using numbers?

Question

Is it possible to make an enum using just numbers in C#? In my program I have a variable, Gain, that can only be set to 1, 2, 4, and 8. I am using a propertygrid control to

Answer 1

use explicit value assignment in the enum:

private enum GainValues 
{
   One = 1, 
   Two = 2, 
   Four = 4, 
   Eight = 8
}

Then to enumerate through these values do as follows:

GainValues currentVal;

foreach(currentVal in Enum.GetValues(typeof(GainValues))
{
   // add to combo box (or whatever) here
}

Then you can cast to/from ints as necessary:

int valueFromDB = 4;

GainValues enumVal = (GainValues) valueFromDB;

// enumVal should be 'Four' now
