Question

At the moment, I’ve got working:

public void logowanie()
{
int x=5,y=5;
...
}

private void button2_Click(object sender, EventArgs e)
        {
            Thread thread2 = new Thread(new ThreadStart(logowanie));
            thread2.Start();
            //logowanie("xd", "xd", "xd");

        }

And that works. Is it possible to make something like

public int logowanie(int x, int y)
{
...
}

private void button2_Click(object sender, EventArgs e)
        {
            Thread thread2 = new Thread(new ThreadStart(logowanie(5,5)));
            thread2.Start();
            //logowanie("xd", "xd", "xd");

        }

I’ve just started with threading things. Thanks

While you could use ParameterizedThreadStart, I’d probably just use a lambda expression:

private void button2_Click(object sender, EventArgs e)
{
    Thread thread2 = new Thread(() => logowanie(5, 5));
    thread2.Start();
}

Note that if you call this in a loop, you’ll need to be careful because of the way that variables are captured by lambda expressions:

// Broken (before C# 5)
foreach (string url in urls)
{
    new Thread(() => CrawlUrl(url));
}

// Fixed
foreach (string url in urls)
{
    string copy = url;
    new Thread(() => CrawlUrl(copy));
}

This is only an issue in certain situations where you’re capturing a variable and really want to capture the current value instead, but it’s worth knowing about.
