Given the listing

enum Foo{A, B, C}

the code below converts from enumto stringand vice versa:

var values = 
from name in Enum.GetNames(typeof(Foo))
select (Foo)Enum.Parse(typeof(Foo), name, true);

So yes, casting works. However, keep in mind that the above request will call the method ArgumentExceptionif the method Enum.Parsereceives a value that cannot be parsed.

This updated version only returns values ​​that are processed successfully.

enum Foo{A, B, C}

var values =  
   from name in Enum.GetNames(typeof(Foo))
   where Enum.IsDefined(typeof(Foo), name)
   select (Foo)Enum.Parse(typeof(Foo), name, true);
