[Feature Request] - Enum <-> String

[bseng]

In the case of attributes with the same name and one is enum while the other one is string, use the enum tryparse and enum description function to do 2 way transform.

Hi

What is enum description function ? Could you provide sample mapping code that you expecting in described situation?

[bseng]

for example.

using System;

[Flags] enum Colors { None=0, Red = 1, Green = 2, Blue = 4 };

public class Example
{
   public static void Main()
   {
      string[] colorStrings = { "0", "2", "8", "blue", "Blue", "Yellow", "Red, Green" };
      foreach (string colorString in colorStrings)
      {
         try {
            Colors colorValue = (Colors) Enum.Parse(typeof(Colors), colorString, true);        
            if (Enum.IsDefined(typeof(Colors), colorValue) | colorValue.ToString().Contains(","))  
               Console.WriteLine("Converted '{0}' to {1}.", colorString, colorValue.ToString());
            else
               Console.WriteLine("{0} is not an underlying value of the Colors enumeration.", colorString);
         }
         catch (ArgumentException) {
            Console.WriteLine("{0} is not a member of the Colors enumeration.", colorString);
         }
      }
   }
}
// The example displays the following output:
//       Converted '0' to None.
//       Converted '2' to Green.
//       8 is not an underlying value of the Colors enumeration.
//       Converted 'blue' to Blue.
//       Converted 'Blue' to Blue.
//       Yellow is not a member of the Colors enumeration.
//       Converted 'Red, Green' to Red, Green.

So for string to enum if we can generate the following Colors colorValue = (Colors) Enum.Parse(typeof(Colors), colorString, true);

Ok, and how to handle Enum -> String conversion? Just simply invoking ToString() method?

[bseng]

Yes.

ok, I will try to make this kind of adjustment to the mapping rules

[bseng]

Thanks a lot for your work.

@bseng here's a version with this feature, would you mind to test it? Any feedback is welcome.

Hi @bseng, did you have an occasion to test this new feature?

[bseng]

I haven't got a chance yet.

[bseng]

It works great thanks!
