Let's say I have a struct that contains local environments:

 public struct Environments
    {
        public const string Dev = "DEV";
        public const string Qa1 = "SQA";
        public const string Prod1 = "PROD";
        public const string Prod2 = "PROD_SA";
        public const string Uat = "UAT"; 
    }

And I'd like to pull a set of XElements out of an xml doc, but only those elements that have a key that matches a value in a struct.

this.environments =(from e in 
settings.Element("Settings").Element("Environments")
       .Elements("Environment")
       .Where( x => x.HasAttribute("name") )
        join f in [struct?] on e.Attribute("name") 
        equals [struct value?]).ToDictionary(...)

How would I go about doing this? Do I need reflection to get the values of the constants in the struct?
