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!

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

@naukriabhi3 12 жыл бұрын

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....???

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();

@maringeorgiev4456 8 жыл бұрын

+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

When you run 2 different threads - will they run parallely in the same core processor or will they run on two different processors ?

@killaurnext 10 жыл бұрын

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)

@saurabhtanwer2166 Жыл бұрын

Thread means parallel execution? Is not it is time slicing or context switching

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.

No it,s not mandatory if u want to stop your thread for some time then you can invoke thread.Sleep() method

can u explain when to use forground and background ?

@santoshKoolkarni 10 жыл бұрын

Use background for tasks that don't involve any user interaction.

@santoshKoolkarni 10 жыл бұрын

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.
