Cannot implicitly convert type 'int?' to 'int'.

Question

I\'m getting the error \"Cannot implicitly convert type \'int?\' to \'int\'. An explicit conversion exists (are you missing a cast?)\" on my OrdersPerHour at the return line

Answer 1

If you're concerned with the possible null return value, you can also run something like this:

int ordersPerHour;  // can't be int? as it's different from method signature
// ... do stuff ... //
ordersPerHour = (dbcommand.ExecuteScalar() as int?).GetValueOrDefault();

This way you'll deal with the potential unexpected results and can also provide a default value to the expression, by entering .GetValueOrDefault(-1) or something more meaningful to you.
