I have some code that takes Double.MaxValue and converts it to a string, but
when I try to convert it back to a double, it fails.  Shouldn't the value be
able to be converted back to a double without error?  

Here is a simple code sample that demonstrates the problem:

           try
           {
               Double dbl = double.MinValue;
               //String sdbl = dbl.ToString();  // This errors as well
               String str = dbl.ToString("N");

               // This throws   "Value was either too large or too small
for a Double."
               Double dbl2 = Convert.ToDouble(str);
           }
           catch (Exception ex)
           {
               System.Diagnostics.Debug.Write(ex.Message);
           }
