有没有一种方法可以在.NET中重载属性 [英] Is there a way to Overload a Property in .NET

问题描述

我已经做了很多方法重载，但是现在有一个我想重载属性的实例. Visual Studio中的IDE似乎允许这样做，因为我实际上可以设置两个重载，但是我收到一条错误消息，指出这是无效的，因为它们仅在类型上有所不同.我想我的语法中缺少什么?

I've done plenty of Method Overloading, but now I have an instance where I would like to Overload a Property. The IDE in Visual Studio seems to allow it, since I can actually set up the two overloads, but I get an error saying it is not valid because they only differ in type. I think I'm missing something in my syntax?

我希望能够使用两个(或多个)不同的自定义类作为我的媒体资源的类型.

I want to be able to use two (or more) different custom classes as the Type for my property.

Public Overloads Property myFlexibleProperty() As myCustomClass1
      Get
         Return _myFlexibleProperty1
      End Get
      Set(ByVal value As myCustomClass1)
         _myFlexibleProperty1 = value
      End Set
   End Property

   Public Overloads Property myFlexibleProperty() As myCustomClass2
      Get
         Return _myFlexibleProperty2
      End Get
      Set(ByVal value As myCustomClass2)
         _myFlexibleProperty2 = value
      End Set
   End Property

到目前为止，我发现的所有帮助都与重载方法有关.尽管IDE允许我做什么，但我开始认为这是不可能的?

All of the help I have found so far has been concerning Overloading Methods. Despite what the IDE is letting me do, I'm beginning to think this is not possible?

推荐答案

要使过载某种方法或属性，您需要它接受一组不同的参数.由于VB.NET中的属性可以接受参数，因此我想您可以重载它们；但它们必须有所不同.

To overload something--method or property--you need for it to accept a different set of parameters. Since properties in VB.NET can accept parameters, I guess you can overload them; but they have to be different.

所以您可以这样做:

Public Overloads Readonly Property Average() As Double
Public Overloads Readonly Property Average(ByVal startIndex As Integer) As Double

但不是这样:

Public Overloads Readonly Property Average() As Double
Public Overloads Readonly Property Average() As Decimal
