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:

Divide by Zero Error

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.
