try             {                 //声部门控件对象                 UserDepartments objfrm = new UserDepartments();                 //调用添加选项卡的方法                 addTabControl("Departments", "部门信息", MainTabControl, objfrm);             }             catch (Exception)             {                 showMessages objshowMesages = new showMessages();                 objshowMesages.ShowDialog("提示信息", "添加选项卡时出错，请检查是否正确连接数据");             }

这样就可以动态的添加了， 还可以删除

try { MainTabControl.TabPages.Remove(MainTabControl.SelectedTab); } catch { showMessages objshowMesages = new showMessages(); objshowMesages.ShowDialog("提示信息", "已没有项目可删!"); }
