Exception Lists

Quick reference

• 00:04 Okay, a couple of videos ago, I showed you how to catch specific exceptions and
• 00:08 that's super useful.
• 00:09 And I also showed you how to find the exception that you can expect to happen by
• 00:14 actually just pulling up.
• 00:16 In this case, we can pull up exception e, right??
• 00:21 And then inside of here, instead of having text, we could just type in e here, and
• 00:26 this will print out the exception to the screen.
• 00:29 And that's what you're going to want to do most of the time.
• 00:31 But if you want to learn more about these exceptions, if you want to learn what they
• 00:35 are and different things you can do about them, you really need a resource to kind
• 00:39 of, at a glance, look at all the exceptions or to easily look them up.
• 00:43 And of course, you can Google this at any time.
• 00:45 But there's a couple of resources, one specifically I want to show you that
• 00:49 really just lists out all of the exceptions onto the screen.
• 00:53 And there are just many, many as we'll see and
• 00:55 they also have little descriptions for each one.
• 00:57 So it's a nice little resource to, if you get hung up on any of this stuff,
• 01:01 want to learn more, need to learn more.
• 01:03 It's a great place to look.
• 01:04 So let's head over to Google.
• 01:05 And these websites come and go.
• 01:07 So I'm not going to give you the address right away.
• 01:08 I'm just going to show you how I would find this on my own here.
• 01:12 So I go to Google, I would type in C# exception list.
• 01:18 And then when you do that, you get all kinds of things,
• 01:21 and you might think to go to the Microsoft page, right?
• 01:23 Microsoft created C# and all of this stuff.
• 01:26 But if you do, it's not all that useful.
• 01:30 You can kind of click around here, not great.
• 01:33 So I don't recommend that Microsoft docs.
• 01:37 What I might recommend is this next one listed,
• 01:39 it's the completecsharptutorial.com, click on this.
• 01:43 And here, we've got exceptions and the conditions,
• 01:46 sort of a little description of each one.
• 01:49 And you could see, man, there's dozens of these things..
• 01:53 So I'm not entirely sure this is an extensive list,
• 01:58 but it is a pretty good list.
• 02:01 And as far as I can tell, one of the bigger lists out there.
• 02:04 So we can come through here and just kind of look at some of these.
• 02:07 AccessViolation, AggregateException, and
• 02:10 why is it important to kind of read through these and look at these.
• 02:13 Well, you're just getting started.
• 02:15 You don't really know the types of errors and
• 02:17 exceptions you're going to come up against as a coder.
• 02:20 And I showed you a couple of videos how to find specific exceptions in your
• 02:24 specific code.
• 02:25 But you may not even know there could be an exception in a certain case, right?
• 02:30 So it's just a good idea to come through here and just spend a few minutes sort of
• 02:34 reading these things, and maybe something will stick.
• 02:37 And as you're writing code, you'll remember away, wait,
• 02:39 wasn't there an ArgumentException?
• 02:41 Yeah, there was, go back and look it up, and
• 02:44 it's thrown when invalid argument provided to a method, right?
• 02:47 So not a huge description here, but enough to sort of send you on the right track and
• 02:52 maybe Google something else in more detail later on.
• 02:54 So ArithmeticException, ArgumentOutOfRangeException.
• 03:00 We had that one, didn't we?
• 03:01 I think we did.
• 03:02 Yeah, an argument is outside the allowable range.
• 03:05 BadImageFormatException if you're dealing with images, I guess.
• 03:10 Let's see, what else, what's interesting through here.
• 03:12 DivideByZeroException, there's the one we had earlier.
• 03:15 It's thrown in there as an attempt to divide an integral or
• 03:18 decimal value by zero.
• 03:20 Okay, we know that from math back in grade school or whatever.
• 03:24 DllNotFound, that's interesting.
• 03:26 FormatException, I think we had that one too, right?
• 03:29 Other IndexOutOfRange, what was the other one?
• 03:32 But like I said, come through here and just read through all these.
• 03:36 I would really spend 10 minutes or so just reading all of these and the descriptions.
• 03:42 Like I said, you're not going to memorize all these.
• 03:44 You shouldn't memorize all of them, but it's a good idea to just sort of
• 03:47 familiarize yourselves with them if nothing else.
• 03:49 StackOverflowException, that's a good one, right?
• 03:53 TimeoutException, IO Exceptions, input, output, right?
• 03:57 Interesting, very cool.
• 03:59 Like I said, this is not an extensive list, I don't think, but it's a really
• 04:03 good place to start, sort of familiarize yourself with these exceptions.
• 04:06 And it's just good fun to nerd out on this stuff, right?
• 04:10 So that's all for this video.
• 04:11 In the next video, we'll start to look at classes.
