在线程里打开窗口

 public void threadCreateTXT()
        {
            Thread thread = new Thread(new ThreadStart(createTXT));
            thread.SetApartmentState(ApartmentState.STA);//当方法里有打开窗口的内容时，没有这句会异常
            thread.Start();
        }

 

 private void createTXT()
        {
            OpenFileDialog odf = new OpenFileDialog();

            if (odf.ShowDialog() == DialogResult.OK)
            {
                C1XLBook book = new C1XLBook();
                book.Load(odf.FileName);
                XLSheet sheet = book.Sheets[0];
