C#中线程的简单示例

        private void button1_Click(object sender, EventArgs e)        {     
            Thread th = new Thread(new ThreadStart(ImageCopy));            th.ApartmentState = ApartmentState.STA;            th.Start();        }
              Thread th;
       void ImageCopy()        {            Clipboard.Clear();            Clipboard.SetImage(pictureBox1.Image);
            th.Abort();        }
