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!
Excellent, simple and easy to remember tutorial. Best explanation I found so far. Thanks, keep your great job.
Small correction in this vedio : Background thread will live until the life time of last foreground thread belongs to that process.
This was an awesome demonstration of Thread. Totally realised, thx a lot. Very understandable.
Hi, Your explanation is too good and i find it very informative and understandable just in one watch.Thanks.
Thanks for the contribution to the C# community!
This is kept simple and straight forward to the point. Good one
Straight to the point and clearly explained. Awesome
Great video! It helped me better understand threading in C#. Thank you!
Perfect for beginners in threading concept, great help
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 video, very informative. Thanks.
can you please describe the timing of thread sleep in this program. Means which function call's when after 4 sec as we see there are in function1 and function 2 calling sequence
Nice class !! Worth for listening
greate.ur explaination s simple & clear.
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....???
wonderful ! it helps me a lot , Thank you very much .
Great tutorial sir. Well done. It helped me a lot!
Nice, Thanks! Good one, greetings from Germany
Sir,may i ask,how does threading differs with delegate chaining? Thank you in advance.
beautifully demonstrated.. thank you alot..
This video helps me a lot. Thank you.
Nice vid! You made this simple.
really good explanation on threading.. thnkz for the video.
Great explanation, thanks for sharing
nicely explained.
very2 helpful for me to understand the Thread. Thanks dude for the video
Much better explanation...Thanks. :)
great tutorial. more power.
hello can you please upload video on multiple parallel http asynchronous programing using await when all
nicely explained..👍
Does
Any one have a example of STA threads managing com object with form
And running other tasks on background threads
Thank you! very easy to understand
Great sharing!
Great tutorial!!!
It's very clear and usefull
Thanks for your nice videos.
I realize diferent beetwen foreground & Backgroung Threads completly...
Thanks for your VERY helpful video !
nice one !!! thank you so much
Very helpful thanks
good explanation. thanks
great learning.
Great video.
Thank you for your videos they are very useful!
in the starting : sheeshap LOL
very usefull...
Nicely explained
Thanks great tutorial
Hi Sir,
Please make video on difference between Finalize vs Dispose in C#
Excellent..!
when he had function 1 & 2 = parallel tasks
when it was just function 1 and explaining foreground and background thread...i guess it technically could be both threaded tasks and parallel tasks (I would go more with threaded tasks since you could argue that there is only one thread)
great video....
Good one
so what is use of background thread
Awesome!
Thread means parallel execution? Is not it is time slicing or context switching
awesome....
after 12 years
Task - An opeartion
Thread - process a Task (or executes an operation)
Multithreading - process multiple task parallel
Hiee sir , in ur 1st example i've added IsBackground = true for both the function but Function1 and Function2 is still looping and executing after Main thread has ended. what m i doing wrong ?
Thread obj1 = new Thread(Function1);
Thread obj2 = new Thread(Function2);
obj1.IsBackground = true;
obj2.IsBackground = true;
obj1.Start();
obj2.Start();
Console.WriteLine("Main application has ended");
Console.ReadKey();
+Saurabh Main thread hasn't ended after displaying its message on the console. It waits for your next command Console.ReadKey(); Delete that, start the app with Ctrl + F5 evth should be fine
great video thanks>........
Very good
sir please tell me threadstart delegate
She is very sharp.
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.
When you run 2 different threads - will they run parallely in the same core processor or will they run on two different processors ?

Nice one thanxxxxxxxxxxxxxxxxxxx
good video
Nice 👍
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!
great. waoooh
Why? What is the difference?
sir i've question if we don't call thread.sleep() method in both Function1 and Function2 Method then what will happen
and its mandatory that we must call sleep() in threading
No it,s not mandatory if u want to stop your thread for some time then you can invoke thread.Sleep() method
@@MB26566 Thread.Sleep() was used just for demonstration purposes.
you should not mix up the definition for threaded tasks and parallel tasks.
Great vid, its like taking lessons from Frank Sinatra :D in other words.... thanks.
Did i mix up ?
No
can u explain when to use forground and background ?
Use background for tasks that don't involve any user interaction.
Also background threads abruptly end when all foreground threads end. So none of the cleanups will be performed including any cleanup in the finally block. So if any cleanup is important, use foreground thread or implement some way to cleanup the background before ending last foreground thread.
Santosh Kulkarni Nice :) Thank you :)
Santosh Kulkarni Really good explanation.

Great another Hindu tutorial
add should. be stop..
Hindu is a religion... not a race. That's like saying "Great another Christian tutorial." He sounds Indian, but I could be wrong. Also he knows his shit that's clear, so I don't mind the accent. I'm not an ignorant American.
Americans invented this shit dude
