Question

我有Class ABC。我想写两个属性它。我在代码中已经提到了一个。另一个是single dimensional array。

Public Class ABC
    Private m_Type As String  
    Private SomeArray........need to write a property for array which will be of type `int`

    Public Property Type() As String
        Get
            Return m_Type
        End Get
        Set(ByVal value As String)
            m_Type = value
        End Set
    End Property  

End Class

我不确定如何为可以在List(Of ABC)中使用的数组定义属性。数组的属性可以是只读数组，因为我将

对其进行硬编码。

所以基本上当我这样做时，

Dim SomeList As New List(Of ABC)

在for循环中我需要这样的东西，

SomeList.Item(index).SomeArray......this will give me all the items inside the array

Answer 1

您可以使用与声明其他属性类型相同的方式声明数组属性：

Public Class ABC
    Private _Type As String
    Private _SomeArray As Int32()

    Public Property SomeArray As Int32()
        Get
            Return _SomeArray
        End Get
        Set(ByVal value As Int32())
            _SomeArray = value
        End Set
    End Property

    Public Property Type() As String
        Get
            Return _Type
        End Get
        Set(ByVal value As String)
            _Type = value
        End Set
    End Property
End Class

例如，如果要在列表的一个数组中循环所有Integers：

Dim index As Int32 = 0
Dim someList As New List(Of ABC) 
For Each i As Int32 In someList(index).SomeArray

Next

Answer 2

如果你不打算在获取和集合中做任何特殊的事情，你可以稍微简化你的代码，如下所示（它将只读数组初始化为包含数字1,2,3和4））：

Public Class ABC
    Public Property Type As String  
    Public ReadOnly Property SomeArray As Integer() = {1,2,3,4}

End Class

要在List中使用的Array的属性
