Question

如果我的列表框包含以下Microsoft Word颜色索引，那么如何获取它的值并将其设置为颜色索引？

<ListBox x:Name="FindColorListBox" HorizontalAlignment="Left" Height="135" Margin="10,198,0,0" VerticalAlignment="Top" Width="107">
    <ListBoxItem Content="None">
        <ListBoxItem.DataContext>
            <word:WdColorIndex>wdAuto</word:WdColorIndex>
        </ListBoxItem.DataContext>
    </ListBoxItem>
    <ListBoxItem Content="Auto">
        <ListBoxItem.DataContext>
            <word:WdColorIndex>wdAuto</word:WdColorIndex>
        </ListBoxItem.DataContext>
    </ListBoxItem>
    <ListBoxItem Content="Black">
        <ListBoxItem.DataContext>
            <word:WdColorIndex>wdBlack</word:WdColorIndex>
        </ListBoxItem.DataContext>
    </ListBoxItem>
</listbox>

因此，用户点击＆＃34; FindColorListBox＆＃34;项目，说＆＃34;黑＆＃34;，我想从Word.WdColorIndex.Black获取datacontext以便设置

find.ColorIndex = Word.WdColorIndex.wdBlack

基本上我认为它是这样的：

find.ColorIndex = FindColorListBox.SelectedItem.DataContext;

但显然这不对......

嗯，你几乎拥有它：

var selectedColorIndex = (Word.WdColorIndex)(((FrameworkElement) 
     (FindColorListBox.SelectedItem)).DataContext)

获取ListBox选择的项DataContext值
