What happens when this program is compiled and run?

try
{
    Console.WriteLine(int.Parse("ten"));
}
catch (Exception)
{
    Console.WriteLine("general");
}
catch (FormatException)
{
    Console.WriteLine("format");
}

It does not compile

Expecting general: at run time blocks are tried top to bottom, but a general catch above a specific one is compile error CS0160, so the program never runs.
Expecting the most specific catch to win wherever it is written: the order matters, so specific classes go above catch (Exception).

How would you reorder the blocks so that the program prints format?
What would the program print with only the catch (Exception) block left, and why?
