2:25 [Ctrl] + [/] is a better commenting hotkey, albeit the one in the video is good to know b/c it is used in other Microsoft platforms such as SSMS.

Gets index out of range exception : "You told me to read these things ... but i'm just gonna panic and not read" Me: 🤣😂 You guys are the best at teaching concepts!!!!

[@ADAM63639]

2:54 Read errors 4:13 var names = new List { "Some", "Name", "LastName" }; Console.WriteLine(names[1]); Console.WriteLine(names[names.Count - 1]); Console.WriteLine(names[^1]); Console.WriteLine(names[^2]); foreach (var name in names[..^2]) Console.WriteLine(name);

[@BluezConcepts]

why can't i say names.length-1? why count-1?

[@tmhchacham]

It depends on the object being used. You just have to know which is implemented. Luckily, the editor will help you figure that out.

[@olamideabass5587]

you use .Length for arrays and .Count for lists

[@hipertracker]

names[^2] looks weird, names [-2] is more cleaner

[@DasDron]

[-2] is not working in C# sadly, so that's why they used [^2]

[@bilkisuismail6096]
