[Help] C# Threading

[Ollori]

I'm not really familiar with threading and it's confusing me on how to make like a cracker

Basically, I have the "one threaded cracker" that I made and I can't figure out how to make it multi threaded where it picks lines from an (array string? / list)

Any informations would be useful, thanks in advnace

 

If you're too lazy to type, just link me some webpage & I'll understand it easily

Basic info about multi threading. I could go in to detail, as I have made checkers that have 10k cpm because of threading, but It is to long to explain.

Hey that's useful, thank you, however, I was wondering, how do you assign a part of a combolist to it? I usually just do foreach line in an array, that's whats confusing me the most

Threads are generally for system side duties.

 

You want Parallels. You can use Parallels just like how you were talking about your foreach loop, but I prefer for loops  An example:

Console.WriteLine("Amount of threads: ");
string amntStr = Console.ReadLine();
int amnt = Convert.ToInt32(amntStr);
string[] combos = File.ReadAllLines(AppDomain.CurrentDomain.BaseDirectory + "combo.txt");

Parallel.For(0, combos.Length, new ParallelOptions() { MaxDegreeOfParallelism = amnt }, l =>
{
    Console.WriteLine(amnt);
    Console.WriteLine(combos[l]);
});

You can control amount of "threads" with MaxDegreeOfParallelism

Thank you so much, guess I can call it solved now

I would highly recommend you to check out Task since it's alot easier to use with asynchronous operations. I have used it with almost every cracker i have built for the last 3-4 years.

In my experience Tasks are very CPU intensive.

 

You can wrap parellels in a task.

Task t = Task.Run(() =>
{
    Parallel.For(x, x, new x() { x }, l =>
    {
        //do work
    });
});

Well that would depend on how you use your Task. I can run around 10-20k Tasks at the same time and it won't even take 100MB of my CPU.
Althought it can eat alot of RAM insteed. Haven't used Parallel so can't really give my 2 cents on it.

From my understanding so is the biggest diffrence that Tasks run without waiting and Parallel will wait.

Edit:
Here is a quick PoC should run but i just wrote it from memory so haven't tested it. Although this is not even near the best way to write a async task running process.
You should also set a limit on how many Tasks that is allowed to run at the same time which i have not done in this one.

List<Task> tasks = new List<Task>();
            int tasksTested = 0;
            int maxTasks = 10000;
            for (int startedTasks = 0; startedTasks < maxTasks; startedTasks++)
            {
                tasks.Add(
                    Task.Run(() =>
                    {
                        tasksTested++;
                        Console.WriteLine("Started task " + tasksTested);
                        Thread.Sleep(50); //Remove this and it will probably max out the CPU
                        Console.WriteLine("Ended task " + tasksTested);
                    })
                );
                Thread.Sleep(1);
            }
            Task.WaitAll(tasks.ToArray());
            Console.ReadLine();

I haven't touched on this topic in a while but I feel like I remember that Tasks execute quicker than a Parallel loop, to the OP, I'd recommend taking both approaches and seeing what fits you best, also check the performance differences with dotMemory and dotTrace
