如何将Windows窗体重新加载或刷新为原始状态？我使用过this.Refresh();, this.Invalidate();, form.Refresh(),form.Invalidate()

    obj.CourseCategoryId = (int) CourseRegCbox.SelectedValue;
    obj.IDNumber = IDNumberTbox.Text;
    obj.Password = PasswordRegTbox.Text;
    obj.FName = FnameRegTbox.Text;

        if ( UserManagement.UserInfo_Update (obj) > 0 )
        {
            MessageBox.Show ("Record Succesfully Updated!");
            UserInfoForm form = new UserInfoForm ();
            form.Refresh ();
        }
        else …
