The program says to type "done", but it's really looking for "quit".

So "done" just causes an invalid number conversion (and then crashes).

Some other hints:

  • in addition to the total, you will probably want to keep a count of entered numbers in the loop
  • when the loop ends, you can then divide the total by the count to get the average
  • the symbol for a divide operation is a slash ("/')
  • you can then use WriteLine to show that average, much like you already show the total

You can keep a count in the loop where you add the numbers for the total (be sure to declare an initialize count before the loop):

                total += numbers;  // you already do this
                count += 1;        // you could do this too

Then when the loop finishes, you could do something like this:

        Console.WriteLine(" Your average is " + total / count);  // output the average
        Console.WriteLine("Goodbye" );                          // you already do this

And to end the sequence, you could either tell the user to type "quit", or inside the program check for "done" instead of "quit". As long as they match, either way is fine.
