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的列表：

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，但是我在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

我在做什么错？

Answer 1

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

在下面的示例中，仅显示属性Title的内容：

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

另一种方法是将ToString -Method的覆盖层添加到emailFolder -Class：

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

解决了问题。

只需要覆盖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
