c++ - C++ cli access Form variables from class

Question

There is a form Form1 which contains int x; and a class MyClass with .h and .cpp files. How can I access the Form1 variable x from MyClass, without passing it using a method? I think something like Form1.x Maybe is it a bad style of programming? I am just learning..

Answer 1

好吧，它打破了封装，你真的应该有你想要公开的数据的公共 getter 和 setter，允许像你建议的那样访问允许调用者损坏、重新分配等。基本上做他们喜欢的任何事情。您应该添加一种方法getX()以获取更好的名称。
