Hi everyone,
There is an algorithm that is used for operating system and can you post it all codes about c#? It's very complex but can you explain how I can write a code to run many process in c#?

Your question is not at all clear. Please rephrase it and narrow it down to something that is possible to answer.

Solution 1

You need to be careful do you mean multi-processing or multi-threading. I don't think MultiProcessing is possible (or even that necessary) in C#, but I haven't investigated that very deeply. Multi-threading is possible and useful:

Hope that answers your question.

Why would you answer if you "haven't investigated that very deeply"?

There are too many Question and Answers here on CodeProject on the topic, and most of them are mostly concentrated on a simple idea: solving OP's problems ***without*** multi-threading makes no sense. The solutions are also very robust and maintainable.

How can you so easily throw an idea that multi-processing can be impossible or not necessary?
Bringing so baseless and simply false idea well deserve a big 1.

Sorry, Keith,

Wow, I suggest you re-read my answer. I *suggested* he did this via multi-*threading*. He asked for multi-*process*. He must choose one or the other, multi-*processing* in the sense he needs is impossible in c# IIRC is is possible in C. OK there is the Process class, but this isn't applicable here.

Solution 3

You should really try google. I did, and got back almost 58,000 results:

how can i write for sjf preemptive algorithm so? i did sjf non-preemptive in c# but this very complex algoritm to solve preemptive sjf for code :/

for example :
processes / arrival time / burst time / priority
p1 0 8 0
p2 1 4 1
p3 2 1 2

how fine averate time , turnaround time and throught in this example by c# ??
