Every Single LINQ Extension Method With Examples | .NET & C# Essentials

Показать описание
In today's video we're going to cover every single LINQ extension method with examples.

We're going to cover immediate execution vs deferred execution - what's the difference between them and whether or not immediate execution necessarily means iterating over the entire list and realizing the LINQ query.

Dude this is the best video I have ever watched on this subject. You crushed this. No stumbling, no half-assing, no confusion. You were well prepared and taught everything perfectly. Just wanted to comment to let you know.

There's no reason why I should not like this video. Amazing effort, thank you Amichai 🙏

Liked and already subscribed. Am waiting for the PLINQ course! Never heard or used PLINQ but sounds useful. Thanks you!

Best LINQ video in my opinion, and the only one you need to understand the topic, I just clicked on a whim, but I am glad that I did, thank you so much for making it.

Best LINQ video ever. I’ve been using LINQ for a long time and didn’t know half of these methods. 😃👍🏼

I'm not a developer, but I do write code to test software, and I learnt some very nice things here. Great video!

Good vid. I have been doing c# among many languages for over 10 years now. Somethings if you never need it you just dont get to learning it yet from being busy so nice people make these vids.

Great work. Thanks a lot!
Consider making a tutorial about all types of lists :)

Amazing video! So much effort; thank you.

Once small point, I would cover the overload of Zip that takes a collection and a Func as an argument.

That is probably one of the more powerful functions in Linq and strangely very few seem to know about it (it's up there with Aggregate)!

One of my favorites is to check if a list is ordered (there are probably simpler ways but this is pretty show-offish) :

var isOrdered = !list1.Zip(list1.Skip(1), (a, b) => a.Val <= b.Val).Contains(false);

great video !!
one more thing, is there any way to share your README file on this video ? (look like the whole function list)

Your explanations are really simple enough and easy to listen and follow. I also have a question, what is the on screen drawing tool you are using?
