vb.net中键值列表或字典的通用结果

我需要在我的DNN安装中返回州（地区）名称及其缩写值的键值配对列表。在下面的函数中，我成功地向名为RegionList的推断变量获取了所需的结果，但是我无法将这些结果转换为键值配对列表或字典并返回结果。任何帮助都将不胜感激

Public Function GetRegionPerCountry(CountryCode As String) As List(Of KeyValuePair(Of String, String))
    Dim lc As New DotNetNuke.Common.Lists.ListController()
    Dim countryID As Integer
    Dim RegionList2 As List(Of KeyValuePair(Of String, String)) = New List(Of KeyValuePair(Of String, String))

    If Not CountryCode Is Nothing Then
        Dim entryCollection As System.Collections.Generic.List(Of DotNetNuke.Common.Lists.ListEntryInfo)
        entryCollection = lc.GetListEntryInfoItems("Country")
        countryID = entryCollection.Where(Function(x) x.Value = CountryCode).Select(Function(x) x.EntryID).FirstOrDefault()

        entryCollection = lc.GetListEntryInfoItems("Region")
        Dim RegionList = entryCollection.Where(Function(x) x.ParentID = countryID).Select(Function(x) New With {.Key = x.Text.ToString(), .Value = x.Value.ToString()}).ToList()
        RegionList2 = RegionList
    End If
    Return RegionList2
End Function

试试returnregionList2.Key.Tostring（）哎呀，你想要的是一个列表，而不是字符串本身。我会做一个断点，并确保regionList是您期望的变量类型。
