_下划线作为VB.net中变量前缀的含义 [英] Meaning of _ underscore as a variable prefix in VB.net

问题描述

Visual Basic中的下划线是什么意思?我有以下代码:

What is the meaning of underscore in visual basic? I have this code:

Private _isAuthenticated As Boolean

与做这件事一样吗?

Private isAuthenticated As Boolean

还是在名称前面加下划线有什么特别之处?

Or does adding the underscore to the front of the name do something special?

推荐答案

这是一个约定.前导_经常表示该变量是该类专用的.此约定通常用于许多不同的语言，而不仅仅是VB.

It's a convention. A leading _ often indicates that the variable is private to the class. This convention is commonly used in many different languages, not just VB.

类似地，它也表明该变量是属性后面的局部变量.

In a similar sense, it also indicates that the variable is the local variable behind a property.

但是它对编译器没有重要意义.

However it has no significant meaning to the compiler.
