I am very impressed by the quality and clarity of your explanation. Hat down.

[@andywilson5677]

This is the best C# channel I've found on youtube. Very clear explanations. Thank you!

[@hurricane8433]

This is the best tutorial on an abstract concept. Thank you Ser.

[@nicholasziglio]

I can't thank you enough for the beautiful and crystal clear explanation! There are so many poor explanations I have wasted my time on.. I'm so happy I found this gem :)

[@Maxim_Grekov]

I'm shocked that Delegates is so easy stuff! When I've started learning Func, Action, Lambdas were so confusing for me. Thank you!!!

The best explanation on KZbin and it has fewer than 1k views.

Hi Jasper! I have to thank you very much because of your mini series I finally understand what a delegate is!! I have no words to thank you!! The only ambiguity is the connection between the lambda expressions and anonymous functions. At 10:25 "a lambda is just a shorthand way of writing and passing an anonymous function to a delegate". Could you explain more?

[@CodingTutorialsAreGo]

The point is simply that when we use a lambda, we don't give it a name. 'Double' is a named function. 'x => x * 2' does the same thing, but doesn't have a name.

[@bioanu]

@@CodingTutorialsAreGo Yes, this is crystal clear. What confuse me is the idea of passing an anonymous function to a delegate. An anonymous function returns a delegate, but I do not know it could be passed to a delegate

[@CodingTutorialsAreGo]

@@bioanu No. Just like any function, and anonymous function returns and object of a particular type or void. I think the confusion may be down to the fact that C# also has a redundant feature to create anonymous functions that uses the keyword 'delegate'. But these functionally equivalent to lambdas and are completely superseded by them.

Excellent lesson. Finally I understood delegates and func. Thank you. Any chance of a lesson on Interface with real world implementation or examples.

[@sky-soft-2024]

Thank you :)

[@giridharamadhavan2200]

Is there any situation where we have to use only delegate and not by using Func or Action ?

[@CodingTutorialsAreGo]

Thanks for the question. I'm not sure quite what you're getting at. Certainly you don't have to use Func or Action, you just need to declare a variable of a delegate type, which you could do explicitly or with other generics such as Predicate. Also, you could simply assign into a variable with implicit type var, but in practice it doesn't get you very far.
