无法使用 IMAPX 获取电子邮件文件夹名称

Question

我正在使用此代码获取电子邮件文件夹列表：

Class emailFolder
    Public Property Title As String
End Class

Public Shared Function GetFolders() As List(Of emailFolder)
    Dim folder = New List(Of emailFolder)
    Dim foldername = client.Folders
    For Each parentFolder In foldername
        Dim parentPath = parentFolder.Path
        If parentFolder.HasChildren Then
            Dim subfolders = parentFolder.SubFolders
            For Each subfolder In subfolders
                Dim subPath = subfolder.Path
                folder.Add(New emailFolder With {.Title = parentFolder.Name})
            Next
        End If
    Next
    Return folder
End Function

Public sub btn_click handles Button1.click

ListView.ItemSource=GetFolders

我不知道我的代码有什么问题，但我在 ListView 中得到的项目（顺便说一句，我在 wpf 中）看起来像这样：

 MyApplication++emailfolder
 MyApplication++emailfolder
 MyApplication++emailfolder
 MyApplication++emailfolder

我做错了什么？

问题已解决..感谢大佬们的评论！！

只需覆盖 ToString...完整代码：

   Class emailFolder
    Public Property Title As String
   Public Overrides Function ToString() As String
            Return Me.Title
        End Function
End Class

  Public Shared Function GetFolders() As List(Of emailFolder)
    Dim folder = New List(Of emailFolder)
    Dim foldername = client.Folders
    For Each parentFolder In foldername
        Dim parentPath = parentFolder.Path
        If parentFolder.HasChildren Then
            Dim subfolders = parentFolder.SubFolders
            For Each subfolder In subfolders
                Dim subPath = subfolder.Path
                folder.Add(New emailFolder With {.Title = parentFolder.Name})
            Next
        End If
    Next
    Return folder
End Function

Public sub btn_click handles Button1.click

ListView.ItemSource=GetFolders

Answer 2

如果定义 ListView 的 ItemTemplate，则可以定义 ListViewItems 的外观。

下面的例子只会显示属性 Title 的内容：

<ListView>
    <ListView.ItemTemplate>
        <DataTemplate>
            <TextBlock Text="{Binding Title}" />
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

另一种方法是将 ToString 方法的覆盖添加到 emailFolder-class:

Class emailFolder
    Public Property Title As String

    Public Overrides Function ToString() As String
        Return Me.Title
    End Function
End Class
