    In this video we will try to understand what is the use of Yield keyword. Yield keyword helps us to do custom stateful iteration over .NET collections. In this video we will understand the same with a full demonstration.
    We are also distributing a 200 page Ebook ".NET Interview Question and Answers". If you want this ebook please share this video in your facebook/twitter/linkedin account and email us on

    Although I very much dislike videos where some programming practice is presented as they are waste of time, hard to follow and very little information is actually given. But, this one is a rare and blistering exception. Great tutorial. Appreciate the effort with additional animation. Thumb up. Sorry I have only one.

    I dint understand a word, coz I dont speak french, but every your move.next() clearly described the intention of change with a great finale at async/await . Amazing knowledge. Will try to step through this in JS and then will do for C#.

    Great video.15 years and today I finally bothered to look up the yield keyword. Happy days!!!
    It was easy enough to follow.
    The only constructive feedback, if I may, would be to help you develop would be that if you ever intent to work in an English speaking country, it is hard to understand.
    Why does the Indian accent omit the "yee" from the beginning of "yield"? Also - the using the singular for "iteration" when you mean the plural "iterations".
    It's only minor but I thought worth mentioning because you're clearly a professional.

  • @ishan9815
    @ishan9815 4 года назад

    Sir, with due respect your explanation about preserving the data is a little confusing.
    If we observe the debugging closely, what 'yield' keyword does here is:
    When we reach the yield keyword in the for-loop, it returns to the caller BUT DOESN'T EXISTS the method and when another iteration comes, the execution resumes to the very next line of the yield return statement, which here is the end curly brace of the loop, so then it again iterates but from the same iteration count as you said in the video earlier, like it is resuming the execution of this method. So the running total variable never gets destroys but gets out of scope for a short period of time and as the execution of the loop resumes, it comes back in the scope with its existing value.
    Great Video sir, now it makes sense to me how CoRoutines work in Unity.
    Thank you

  • @minastaros
    @minastaros 10 месяцев назад

    It even works when the generator function walks over deeply nested data structures, using recursion, thus, calling itself in potentially several levels and probably foreach-loops. And the receiver just gets one value after the other neatly serialized... That's not _easily_ possible without pre-buffering the results in next_element()-like functions.

    @Shivprasad Koirala Sir, Why create another Filter method for getting values greater than 3 ? We can do this simply inside Main Method also.. ? Before printing the values to the console, just check whether it is greater than 3 or not... then what is the benefit of using Yield here ?
