构建类 [英] Constructing Classes

问题描述

我找到了一个关于XML序列化的优秀教程：
http： //addressof.com/blog/articles/E...alization.aspx

当他创建一个类属性时，它看起来像这样：

公共类驱动程序

私有_wave为字符串

公共属性Wave（）为字符串

获取

返回_wave

结束获取

设置（ByVal值为字符串）

_wave =值

结束集

结束财产

结束班级


我的问题是，这样做似乎同样有效：

公共类驱动程序

Public Wave As String

结束类


是否有理由使用Property方法？

I found an excellent tutorial on XML Serialization:
http://addressof.com/blog/articles/E...alization.aspx

When he creates a class property, it looks like this:
Public Class Drivers
Private _wave As String
Public Property Wave() As String
Get
Return _wave
End Get
Set(ByVal Value As String)
_wave = Value
End Set
End Property
End Class

My question is, it seems to work equally well when done this way:
Public Class Drivers
Public Wave As String
End Class

Is there a reason to use the Property method?

推荐答案

属性基本上是Getter / Setter方法。在设计师中，他们将会在组件的属性页面中显示
。在这样的属性背后理论上隐藏

你的实现（_wave）总是更好。您的

类可能在_wave上有其他依赖项。例如，您可能有一个

" _subwave" item，包含_wave的子集。显然，当用户

设置一个新的_wave时，_subwave仍然引用旧的_wave。在这个

的案例中，您的财产设置了方法将能够释放参考。

这只是一个例子。它们非常灵活，并且不会在最基本的形式中增加很多开销。

Properties are basically Getter/Setter methods. In the designer, they will
appear in the property page of a component too. It is always better to hide
your implementation ( _wave) in theory behind a property like this. Your
class may have other depencies on _wave. For example, you may have a
"_subwave" item, which contains a subset of _wave. Obviously, when the user
sets a new _wave, the _subwave is still referencing the old _wave. In this
case, your property "set" method would be able to release the reference.
Thats just one example. They are flexible and don''t add much overhead in
their most basic form.

AND。 。 。


此外，它允许您处理输入或在它之前验证它

设置内部变量

AND。 。 。


在VS2005中，您可以在级别下方设置get / set（互相
独家）的访问修饰符，并且独立于属性访问

modifer。因此，例如，可以将属性get设置为public并将设置

设置为freind等。

AND . . .

In VS2005, you are able to set access modifiers for get/set ( Mutually
Exclusively ) below the level and independently of the properties access
modifer. So for example, the property get could be set to public and the set
to freind etc.
