This video is a brief overview for beginners on how you can effectively use arrays, lists, and dictionaries in your C# dotnet applications. I skip over the nitty-gritty details of why each data structure has different performance characteristics or how they function exactly under the hood, but instead, focus on how you can leverage them. If you want more in-depth explanations, let's hear about it in the comments!

Super helpful in understanding the differences in data structures coming from JavaScript. Key takeaways from your explanations for me: 6:27 Use Arrays for fixed size collections 12:55 Use Lists for dynamic size collections 16:28 For Dictionaries, you can overwrite an existing value by assigning an item using "dictionary[index] = value" bracket notation. But if you want to avoid overwriting an existing value, we can use the "dictionary.Add()" method.

So basically Arrays are static with single data type collection, Lists are dynamic with single data type collection and Dictionaries are dynamic with 2 different data type collection....That's it?

@DevLeader 25 дней назад

@@uditjagtap8317 the first part is a good summary. The second part is true, but it leaves more to be desired in the definition. Dictionaries have very different characteristics. If you want to find a specific element in an unsorted array or list you need to step through it. A dictionary, the lookup by key is extremely efficient and you don't need to walk through the elements. Dictionary keys must also be unique, but there's no such constraint on an array or list 🙂

@@DevLeader Oh...get it thank you for the explanation 😄

Sir can't find any video on generics?.....

@DevLeader Месяц назад

These collections *are* generics 🙂 are you looking for a more basic introduction to the concept? Let me know 🙂

Lots of talk and incomplete explanation

@DevLeader 6 месяцев назад

What was not explained? There are several ways to offer feedback, and simply saying something negative without much context is *exactly* what your own criticism was of the video. - What did you feel was superfluous and extra? ("Lots of talk") - What did you feel was an incomplete explanation? - What's your level as a programmer? Are you junior, and still feel that you don't get the concept? Or are you advanced, and feel like there's other aspects that you'd mention? Thanks for taking a moment to offer feedback, but that's inactionable due to "incomplete explanation".
