Anonymous methods in c# .Net step by step - Interview Question.

See our other Step by Step video series below :-

In this .NET and C# video we will see a small sample for Anonymous methods and in what situations to use anonymous methods.

many people possess sound knowledge of subject but not all of them have good presentation skills.
Really Good presentation... Bonus: Like the way you summarize in the end! thanks for such useful tutorials... cheers!

superb video, i have never seen better explanation for begineers reg:delegates and anonymous methods than this one.

[AmmarTravelDiaries]

Sir . you know how to deliver knowledge.... thank you very much sir.. You explain a very important concept in simpler terms... its very easy to understand.

[saikovvuri]

Excellent insight into anonymous performance benefit. Great Job.

[BigyanChap]

Wow. This is like Electronics Lab. You made your point with experiments. Cool. I like it.

Delegates for anonymous methods are cached, so there is a small overhead for checking if the delegate already exists in the cache. On the other hand, if you run the method more than once, it will reuse the cached delegate instead of creating a new one.

Delegates for named methods are not cached, so it will be created each time.

Excellent vedio, i don't have knowledge of stopwatch class, now get it .
Thanks a lots... pl post more vedio which explained in very simple manner

[kunalful]

At the last of video, " If we want to use the delegate only inside the same function", does it mean that we can't instantiate PointtoAddFunction delagate to invoke a different method with the same signature or has a different meaning?
Please help me on this.

[KDOERAK]

Very good: short and clear. Thank you.

[durgaprasad-ouhv]

super video for understanding anonymous methods

[rishikeshnerkar]

Can't you make updated video on this?

[abhijithk]

Can we have complex code in anonymous methods ? if it gives better performance why not use it for all del methods?

[nirman]

@Abhijith k - I think this has also to do with code re-usability... because its an inline code, it cannot be used anywhere else. May be like wrapping up an anonymous method inside a named method and call the named method. That would be the solution.. however, not sure if that makes sense!

hi i follow your videos. i had faced one  interview question. --can we make a class that cannot be instantiated
i said yes by using private constructor in  class. Then the he asked if the class cannot be instantiated what is the use, have you used in your project, and in dot net  every class will be instantiated at least once, if you have this class will it throw errors ..

Please provide me a video on this

i made a performance test between if and switch with Stopwatch class, the result is switch x3 faster than if

[BrutusPalmeira]

So calling a function takes that much time

[Pelibluepampum]

This is incredible misleading, and not real world scenarios. What is slower is the instantiation of the delegate and not the code that runs.
If you have the method created, just call it (Add(2, 2, )).
And also if you are creating a delegate inside a loop, that's probably just plain bad design.
