c# two object in class dont work thread

Question

I have a construct like this:

private readonly List<Thread> thr = new List<Thread>();

In a class i have a method with one parameter that i want to call threaded.

    public void testthr(object xxx)
    {
     ......
    }

on button click i start a thread

        for (Int32 i = 0; i < textBox8.Lines.Length; i++)
        {

            var thr1 = new Thread(testthr);
            thr1.Start(textBox8.Lines[i].Trim());

            thr.Add(threadz);

        }

How to make a thread with more than one parameter? Like:

    public void testthr(object xxx, string yyy)
    {
     ......
    }

this class in thread start ?

This question is really hard to understand. Please format your code samples properly, and tell us what errors, if any, you're getting from the code you tried that doesn't work. — millimoose, Sep 15 '13 at 17:42

If you want to pass multiple values to a thread proc, you need to create an object to contain them. There are several ways to do that. The easiest is probably to use a Tuple:

for (Int32 i = 0; i < textBox8.Lines.Length; i++)
{

    var thr1 = new Thread(testthr);
    var data = new Tuple<string, string>(textBox8.Lines[i].Trim(), "hello");
    thr1.Start(data);

    thr.Add(thr1);

}

public void testthr(object state)
{
    var data = (Tuple<string,string>)state;
    var item1 = data.Item1;
    var item2 = data.Item2;
    ...
}

thank you for Jim Mischel its replay ok. how to this tuple starting semaphore thread ? — Mustafa Kaya, Sep 15 '13 at 18:33
