Passing delegate with return type other than void in thread

Question

I want to pass a delegate with the return type as ArrayList as parameter of thread and want to store the values in an ArrayList as well. Any help in this regard will be appreciated.

Answer 1

Instead of having a return value you could try passing in another parameter by reference:

private class ThreadArguments
{    
    public ArrayList List1 { get; set; }
    public ArrayList List2 { get; set; }

    public ThreadArguments(ArrayList list1, ref ArrayList list2)
    {
        this.List1 = list1;
        this.List2 = list2;
    }
}

Thread myThread = new Thread(new ParameterizedThreadStart(...));
myThread.Start(args);

So the return value is effectively replaced by list2.
