Question

I have a background worker which invokes parallel threads for list items

 doWork()
    {
    Parallel.foreach(list1, a=>
    {
       while(true)
       {
             //do some operations
       }
    });

    Parallel.foreach(list2, b=>
    {
        while(true)
        {
            //do some operations
        } 
    });
    }

If i want to run both of these lists together parallelly, should i create another thread as their parent or anyother way?? i am getting both the lists separately so combining them is not an option.And i am running infinite loops inside both of them.

You can use tasks to run the two loops on separate threads. Use normal foreach loops.

var t1 = Task.Factory.StartNew(() => 
{
    foreach(var a in list1)
    {
        //do some operations
    }
});

var t2 = Task.Factory.StartNew(() => 
{
    foreach(var a in list1)
    {
        //do some operations
    }
});

// This will block the thread until both tasks have completed
Task.WaitAll(t1, t2);
