推荐答案

不要这样做.

您可以通过声明public而不是private来将GridView从一种形式公开给其他形式，但这不是一个好主意-它将两种形式联系在一起，这样一种形式就不会改变而不会影响另一种形式.这违反了OOP的原则.

而是提供一个public属性或方法，该属性或方法接受更改并将其传递到GridView中.这样一来，表单的内部结构就不会暴露出来，并且可以被应用程序的其他部分重复使用.

Don''t do it.

You can expose the GridView from one form to others, by declaring it public instead of private but it is not a good idea - it ties the two forms together so that one form cannot change without affecting the other. This is against the principles of OOP.

Instead, provide a public property or method which accepts the changes and passes them into the GridView. That way, the internals of the form are not exposed and it can be re-used by other parts of your app.
