推荐答案

不要。

这与在另一个表单打开的表单上访问数据相同 - 它将控件的设计锁定在一起并防止在考虑它们对外界影响的情况下进行更改。



相反，在外部控件中创建一个属性，返回所需的信息。它可以通过它的内部控制得到它，因为它的设计决定了 - 但外界不需要知道这个事实。

这使你的程序更清洁，

Don''t.
This is the same as accesing data on a form opened by another form - it locks the design of the controls together and prevents changes being made with considering their effect on the outside world.

Instead, create a property in the outer control, which returns the info you want. It can get it from it''s inner control or not as it''s design decides - but the outside world doe not need to be aware of the fact.
This makes your program both cleaner, and a lot more maintainable.

在你的第一个用户控件中，创建一个属性并解析第二个用户控件。



如：

Hi,
In your first user control, create a property and parse the second user control.

such as :

public class uc1 : UserControl
{
   public UserControl uc2{get; set;}

   //.....rest of your code here
}

public class uc2 : Usercontrol
{
    //....
}
