答

您可以添加一个保存内部UserControl的属性.
You can add a property that holds the inner UserControl.


以另一种形式访问控件是不好的做法.如果您坚持要这样做，只需将控件公开(默认情况下，它是受保护的或私有的).

另外，用户控件内部的控件也不是公共的，因此您可能还需要更改其访问级别.

还有许多其他更正确的方法来获取另一种表单控件的数据/属性，其中一种是全局静态类，该类由设置/获取该类中属性的其他对象(即表单)操纵，或包含要访问的控件的表单内部的对象，这些对象将公开那些控件的值.
Accessing a control in another form is bad practice. If you insist on doing so, simply make the control public (by default, it''s either protected or private).

Also, controls INSIDE the user control are also not public, so you may need to change their access level as well.

There are many other more correct ways to get to the data/properties of another form''s control, one of which being a global static class that is manipulated by other objects (namely, forms) that set/get properties within that class, or an object internal to the form that contains the controls you want access to that exposes those controls'' values.
