C# Array vs Dictionary vs List a Beginners Guide in .NET

As a beginner programmer or developer, have asked yourself what are the differences between these three types of collections, arrays, dictionaries, and lists.
In this video, I explain what are the features of each of these collections types. I will explain what an array is and the things you can do with an array. I also explain how in some situations it might be a better idea to use a dictionary instead of an array, I also touch on the advantages of using a list in the .NET ecosystem; whether you are using .NET framework or .NET core.

Thank you for the video. I have learnt quite a lot about the three collections, List, Array, and Dictionary types in depth. Also, I have learnt to declare class and creating objects to use with the collections. Moreover, some new methods to use to find and retrieve data from the list and dictionary. I have noted down the ways you hae utilised them. Thanks a lot for providing and sharing the knowledge to me and everyone else.

Thank you. To answer your question regarding IList, etc… look up Interfaces in C# that will answer your question.

[@Dazza_Doo]

Brilliant!
I understand why everyone is using lists of :D

[@nielsSavantKing]

U can also do var user1 = new User {} and for the loop you can do users.count or length

[@thedevlife]

correct, you can also do that.

[@krishna-le8zq]

Nice explanation... Thanks...
Is there any instance where we should use dict over lists

[@saiashok28]

Thanks for the video. Using List won;t internally iterate in loop to find the item? I am asking in terms of performance/efficiency. I agree with list having ability to search by any fields.

[@thedevlife]

I’m pretty sure it does, to be able to find an element you’d have to iterate through the collection. I just don’t know which algorithm is used under the hood.

My guy. Where did you get that shirt?

[@thedevlife]

I found it on Amazon
