I need to convert a list of int values to list of enum values and vice versa. I can create a simple conversion method but wanted to see if there’s a more concise way to handle this.

Here’s what my enum values look like:

public enum AutoShipOption
{
   Monthly = 2,
   Weekly = 1,
   Yearly = 3,
   Undefined = 0
}

And in my class that I use to define a store item, I get a List<int> that I need to convert to List<AutoShipOption>. As I said, it’s easy to create a simple method that handles this that looks like this:

public List<AutoShipOption> AutoShipOptionsMapper(List<int> values)
{
   var options = new List<AutoShipOption>();

   if(values == null || values.Count == 0)
      return options;

   foreach(var item in values)
      if(item > 0)
         options.Add((AutoShipOption)item);

   return options;
}

Is there a more concise way to handle this conversion?
