昏暗与私人/公共 [英] Dim vs Private/Public

问题描述

在一个模块的头部，我希望声明一些全局变量以用于各种子/函数.

At the head of a module, I wish to declare some global variables for use in various subs/functions.

有什么区别

Dim x as string 和 Private x as string/Public x as string，我什么时候会使用一个?

Dim x as string and Private x as string / Public x as string, and when would I use one over the other?

推荐答案

私有和公共控制您声明的变量或对象的范围.

Private and public control the scope of the variable or object you're declaring.

Private 将只允许相关模块/类/任何成员的成员访问实例

Private will only allow members of the relative module/class/whatever to access the instance

public 将允许与模块/类/任何内容相同范围内的任何内容访问它.

public will allow anything in the same scope as the module/class/whatever to access it.

Dim 默认为 public 或 private，这取决于你在做什么.例如，一个类将默认为 private.我建议阅读封装和 OOP 以更好地了解这一点.

Dim defaults to either public or private, depending on what you're working in. A class for example, will default to private. I suggest reading up on encapsulation and OOP to get a better feel for this.
