Consider the code:

class Work
{
    public void DoStuff(string s)
    {
        Console.WriteLine(s);
        // .. whatever
    }
}
class Master
{
    private readonly Work work = new Work();

    public void Execute()
    {
        string hello = "hello";

        // (1) is this an ugly hack ?
        var thread1 = new Thread(new ParameterizedThreadStart(o => this.work.DoStuff((string)o)));           
        thread1.Start(hello);
        thread1.Join();

        // (2) is this similar to the one above?
        new Action<string>(s => this.work.DoStuff(s)).BeginInvoke(hello, null, null);
    }
}

Is (1) an acceptable way of easy starting some work in a seperate thread? If not a better alternative would be much appreciated.

Is (2) doing the same? I guess what I ask is if a new thread is started, or..

Hope you can help a beginner to a better understanding :)
