How to use int.TryParse with nullable int? [duplicate]

Answer 1

You can't do this without using another variable, unfortunately - because the type of out arguments has to match the parameter exactly.

Like Daniel's code, but fixed in terms of the second argument, trimming, and avoiding comparisons with Boolean constants:

int tmp;
if (!int.TryParse(strValue.Trim(), out tmp))
{
    break;
}
intVal = tmp;
