我要怎么取到上面两个动态增加控件的文本值？

        DateTime dt = chengxingshijian.Value.Add(TimeSpan.Parse(lingqi.Text.Trim()));


这个里面不对请教我应该怎么修改？

谁会的 求解啊！感谢大神们！

局部变量怎么取得到

难道提示的还不够，你想想，你在窗体设计器里面拖了一个控件在窗体上，为什么在窗体类的任何地方都可以使用，因为控件的声明是全局的呀

控件是代码添加的 ！不过解决了！通过找到这个控件然后在获取自己需要的，还是谢谢你！

不清楚你打算怎么用。我一般把需要动态添加控件的事情封装成一个类，这样调用的时候更加方便自由。
