c# (Csharp) threading interview question:- What is thread,background thread and foreground thread ?

See our other Step by Step video series below :-

In this video we will first try to understand what is a thread. We will also demonstrate a simple sample of how threads are created. Finally at the end of the video we demonstrate the difference between background and foreground threads.

Much better than my instructor. Short and to the point!

Thanks for the contribution to the C# community!

Small correction in this vedio : Background thread will live until the life time of last foreground thread belongs to that process.

No, I'd say you got it right... The term "threaded application" pretty much implies "parallel" execution of those threads--as long as you assume the threads to be asynchronous. If they are synchronous, then one might argue that the first thread stops to wait for the second and therefore they aren't truly executing at the same time. But with only one core, you don't have much other choice. So while I can see his point, I think you have presented this in an accurate fashion. Thanks!

Excellent, simple and easy to remember tutorial. Best explanation I found so far. Thanks, keep your great job.

[EricAnthonyBurnett]

Great video! It helped me better understand threading in C#. Thank you!

[JonWoo]

Straight to the point and clearly explained. Awesome

[poojapandey]

Perfect for beginners in threading concept, great help

[maxron]

This is kept simple and straight forward to the point. Good one

This was an awesome demonstration of Thread. Totally realised, thx a lot. Very understandable.

after 12 years
Task - An opeartion
Thread - process a Task (or executes an operation)
Multithreading - process multiple task parallel

very2 helpful for me to understand the Thread. Thanks dude for the video

[MikeStock]

Great explanation, thanks for sharing

[tcbetka]

I don't think it matters whether or not the threads are foreground or background. As I understand it, that only affects the persistence of the spawned thread when the parent thread terminates...as you've shown in your demonstration.

I got a lot of information from your video, so thanks again for posting it!

S...Because, Parallel code execution concept revolves around the execution of code in multiple processors....But in case of single processor MultiThreding concept(as demonstarted here), the processor executes for a specific time the code in function 1 and function 2. What this implies is that, the processor executes the code in f1 and then for f2. When it is executing f2, f1 is not executed.So, this is not parallel code execution.

really good explanation on threading.. thnkz for the video.

[musicman]

Excellent video, very informative. Thanks.

Hi Sir,
Please make video on difference between Finalize vs Dispose in C#

[naukriabhi]

Well in the last part of the video..I can see 'The main application has exited' and below that 'Function1 is entered'...How it is possible...I mean as it reaches to the end of the main program first it shouldn't display the 'Function1 is entered' at all.... Is it because of the delay in writing/displaying to the console application (I mean thread reached first to 'Function1 is entered' and then 'The main application has exited' but display wise it looks opposite) or I am missing something....???
