如何在VB.NET中创建一个通用属性？ [英] How do I create a generic property in VB.NET?

问题描述

我想这样做：

I'd like to do something like this:

Private _myCollection As IList(Of T)
Public Property MyProperty(Of T)() as IList(Of T)
    Get
        Return Me._myCollection 
    End Get
    Set(ByVal value As String)
        Me._myCollection = value
    End Set
End Property

基本上，我想要可能是任何类型的项目的集合。然后，我可以这样做：

Basically, I want to have a collection of items that may be of any type. Then, I'll be able to do something like this:

Dim myPropertyValue as <the type of some value>
if (MyProperty.Contains(<some value>))
    myPropertyValue = CType(MyProperty(<some value>), <the type of some value>)

我该怎么做？还是有更好的方法比使用泛型？

How can I do this? Or is there a better way than using a generic type?

推荐答案

您可能需要创建一个泛型类来执行此操作

You may have to create a generic class to do this

Public Class MyClass(Of T)
    Private _myCollection As IList(Of T)
    Public Property MyProperty() as IList(Of T)
        Get
            Return Me._myCollection 
        End Get
        Set(ByVal value As String)
            Me._myCollection = value
        End Set
    End Property
End Class
