Question

I would like to convert object (which holds a string) to double and if it fails (it contains a string which cannot be converted to double) to convert it to string, so that I would have a List<object> with doubles and strings.

I have something like this :
(thisNavigator is XPathNavigator)

object paramValue;
paramValue = Convert.ToDouble(thisNavigator.ValueAsDouble);

Answer 1

Something like this maybe?

static void Add(List<object> list, XPathNavigator thisNavigator)
{
    string s = thisNavigator.ValueAsString;
    double d;
    if(double.TryParse(s, out d))
    {
        list.Add(d);
    }
    else
    {
        list.Add(s);
    }
}
