Question

Given an enum like:

 enum Test
 {
   Hi=0x1,
   Hello=0x2
 }

From the database, I get either a 1 or 2.

I need to concatenate 0x (to display as hex value), when the query returns 1.

I concatenate 0x and when I assign, I get an invalid argument exception.

(Test)Enum.Parse(typeof(Test), reader.GetString(0));

How can this be done?

I think what you’re trying to do is this:

Take a a string representation of a decimal number, and display that
number in hexidecimal form.

If so, try this:

String x = String.Format("{0:X2}", Int.Parse(myInteger));

Or perhaps I’ve misunderstood what your problem is.
