[轉載]無邊框模式時，呼叫SaveFileDialog 時出現ThreadStateException的解決方法

原網址 http://blog.csdn.net/fisher_china/article/details/6043475


//先製作一個DialogState的類別
 public class DialogState
{
        public DialogResult result;
        public FileDialog dialog;

        public void ThreadProcShowDialog()
        {
            result = dialog.ShowDialog();
        }
    }


//在你呼叫SaveFileDialog的類別裡面，加入這個方法
        private DialogResult STAShowDialog(FileDialog dialog)
       {

            DialogState state = new DialogState();

            state.dialog = dialog;

            System.Threading.Thread t = new System.Threading.Thread(state.ThreadProcShowDialog);

            t.SetApartmentState(System.Threading.ApartmentState.STA);
            t.Start();
            t.Join();
            return state.result;
        }


调用时：(使用時)

            OpenFileDialog openFileDlg= new OpenFileDialog();

            openFileDlg.InitializeLifetimeService();

            openFileDlg.Filter = "Config Files (*.config)|*.config| (*.xml)|*.xml";

            openFileDlg.Title = "选择配置文件";

            DialogResult ret = STAShowDialog(openFileDlg); //使用多執行緒的方式執行ShowDialog

            if (ret == DialogResult.OK)
