Try something like this
尝试这样的事情
<ListBox Width="400" Margin="10"
ItemsSource="{Binding Source={StaticResource myTodoList}}">
<ListBox.ItemTemplate>
<DataTemplate>
<TextBlock Text="{Binding Path=TaskName}"
ToolTipService.ToolTip="{Binding Path=TheTooltipText}"/>
</DataTemplate>
</ListBox.ItemTemplate>
</ListBox>
Of course adapt the ItemsSource binding with whatever your binding source is, and the binding Path parts with whatever public property of the objects in the list you actually want to display.
当然，无论您的绑定源是什么，都可以使用 ItemsSource 绑定，并使用您实际想要显示的列表中对象的任何公共属性来调整绑定路径部分。

You could create a style for ListBoxItem. So something along the lines of:
您可以为ListBoxItem. 所以类似的东西：
<Window x:Class="WpfApplication3.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="MainWindow" Height="350" Width="525">
<Window.Resources>
<Style TargetType="ListBoxItem">
<Setter Property="ToolTip">
<Setter.Value>
<ToolTip>
<TextBlock>Hello</TextBlock>
</ToolTip>
</Setter.Value>
</Setter>
</Style>
</Window.Resources>
<Grid>
<ListBox>
<ListBoxItem>
<TextBlock Text="Hello" />
</ListBoxItem>
</ListBox>
</Grid>
</Window>
