C# exception handling ⚠️

C# exception handling tutorial example explained

// try = try some code that is considered "dangerous"
// catch = catches and handles exceptions when they occur
// finally = always executes regardless if exception is caught or not

bro i watched your code since 3 year ago and i will be graduated soon you helped me so much in the university thanks so much

Did a better job at explaining this in a 5 minute video than my proffessor did in a whole lecture!

[dumbbo]

one point is that we can also make use of e.Message to show what the actual exception error occurred. awesome video bro code🙂

"Not considered good practice" Someone should tell Microsoft, omfg.

This has been super helpful, what a legend!

Think you are gonna help me alot in my education - thanks for the vid ::)

Bro, what about using the general Exception catch all and then you can use e.Message and do something like this:

catch (Exception e)
{
Console.WriteLine("something went wrong: " + e.Message);
}

and you will have one exception writing out the specifics in the Message property.

Oh btw is there reason why we typed "e" after exceptions ? I tried without using it and looks like program works perfectly fine.

[mmisterWhite]

If you write good code you should not have any exceptions right? I just made my code so that there will never be exceptions if you try to do something wrobg 😅

[mukesh]

What we can do to run from the beginning after catch the exception?

[Blocky]

bro really just sum up 40 min video from my prof in 5 mins.

[villocity]

If an exception is caught and fixed how do I make the code try again from were it last was?

[ibnOrfi]

We can also use goto statement right? or is it not recommended? which method is better for error handling?

[SlimyMcTee]

How to prevent the exception from happening at all? So instead of just stopping the program, it looped back to re asking the number. Something like:

while (age != 'a number or something') //something that telling age must be a number otherwise it looped back
{
Console.WriteLine("Not a number dummy, type again!")
age =
}

Is that even possible?
