直接这样写 var task1 = Task.Factory.StartNew(() => DoSomeWork(message1, message2)); 如果是winform，你在另外一个线程不能直接访问窗体控件，可以用

private void button1_Click(object sender, EventArgs e)        {            Task t1 = Task.Factory.StartNew(() => k1());            Task t2 = Task.Factory.StartNew(() => k2());        }         void k1()        {            for (int i = 0; i < 100; i++)            {                Thread.Sleep(100);                this.Invoke(new Action(                    () => { this.label1.Text = i.ToString(); }));            }        }         void k2()        {            for (int i = 0; i < 100; i++)            {                Thread.Sleep(100);                this.Invoke(new Action(                    () => { this.label2.Text = i.ToString(); }));            }        }
