Run Time Errors In C# .Net

Run-Time errors are ones that crash your programme. The programme itself generally
starts up OK. It’s when you try to do something that the error surfaces. A common
Run-Time error is trying to divide by zero. In the code below, we’re trying
to do just that:

The program itself reports no problems when it is started up, and there are
no coloured wavy lines. When we click the button, however, we get the
following error message:

Had we left this in a real programme, it would just crash altogether
(“bug out”). But if you see any error message like this one,
it’s usually a Run-Time error.

Look out for these type of error messages. It does take a bit of experience
to work out what they mean; but some, like the one above, are quite straightforward.

You’ll see how to handle errors like this, soon. But there’s one final error
type you have to know about – Logic Errors.
