It's quite hard to understand what you want and would could be your problem - I assume you are a beginner and this ia a "conceptual" question. So try to tell what you want to do in the end, because the question doesn't make any sense to me- It's hard to guess WHAT you don't understand. (if you have problems with basics better (re-)work through any c# tutorial). So what is a "class type reference" and a "string type value"? What I think you have is a "string representation" (XML?) of your DeviceType - so you may ask for how to "parse" it or something like that?

Hi again Anshumaan,

So now I understand your Problem. The question is how to covert between an enumeration value and it's string representation (Name). You are lucky - that's quite easy in .net - ther is a Parse function implemented on the Enum class. Use it like this:

C#

string strDeviceType = "Pulnix";
DeviceType devicetype = (DeviceType) Enum.Parse(typeof(DeviceType), strDeviceType);

Cool, I think this is what you asked for, isn't it?

Kind regards
Johannes

In your example code, DeviceType is not a class, it is an enum, so the variable deviceType is a enum as well (and isn't a reference at all, it's a ValueType)

You cannot add, store or otherwise include a string in an enum: it is a integer based variable type and cannot contain anythign else.

You could create a containing class which holds them both:

C#

public class MyContainer
   {
   public DeviceType DeviceType { get; set; }
   public string Text { get; set; }
   }
