Lambda expressions with multithreading in C#

Question

I am trying to understand why this program doesn\'t work

Expected output: numbers 0-19 in random order What I get when I run: some numbers repeat, sometimes 20 is pr

Answer 1

public void processinThreads()
{
    for (int i = 0; i < 20; i++)
    {
        int local = i;
        Thread t = new Thread(new ThreadStart(()=>DoSomething(local, processCallback)));
        t.Start();
    }
}

Your problem is related to closure over lambda.
