函数与ReadOnly属性 [英] Function versus ReadOnly Property

问题描述

有没有理由使用：


私有newPropertyValue作为整数

Public ReadOnly属性MyProperty（ByRef MyParam as Integer）As

整数

获取

返回newPropertyValue

结束获取

结束物业

而不是：


将MyValue调整为整数

公共函数MyFunction（ByRef MyParam as Integer）作为整数

返回MyValue

结束功能

解决方案

结束属性
而不是：

结束函数

一个实际的原因是ASP不能绑定到一个函数（或至少它

如果不再是这样的话，就不能玩ASP 2.0了。

除了Jim评论之外，我真的不认为这是好形式

有一个属性有参数。

你好 er**********@gmail.com ，


作为一般经验法则，当

时使用属性1.您不需要传递参数（当然除非数据类型是

a集合/列表和参数是项目索引）

2.您不需要进行任何处理


如果条件1或2失败则使用功能。

Is there any reason to use:

Private newPropertyValue As Integer
Public ReadOnly Property MyProperty(ByRef MyParam as Integer) As
Integer
Get
Return newPropertyValue
End Get
End Property

instead of:

Dim MyValue as Integer
Public Function MyFunction(ByRef MyParam as Integer) As Integer
Return MyValue
End Function

One practical reason is that ASP can''t bind to a function (or at least it
couldn''t, haven''t played with ASP 2.0 enough if this is no longer the case).

Hi,

In addition to Jim comments I really dont think it is good form to
have a property that has a parameter.

Hello er**********@gmail.com,

As a general rule of thumb, use a property when
1. You do not need to pass parameters (unless of course the data type is
a collection/list and the parameter is the item index)
2. You do not need to do any processing

If conditions 1 or 2 fail then use a function.
