C# 获取ListView中某一列的全部值

Question

我的窗口上添加了一个ListView ，代码如下：
<ListView Height="179" HorizontalAlignment="Left" Margin="0,26,75,0" Name="listView1" VerticalAlignment="Top" Width="428" ItemsSource="{Binding}" VerticalContentAlignment="Bottom"  HorizontalContentAlignment="Left">
            <ListView.View>
                <GridView AllowsColumnReorder="True" >
                    <GridViewColumn Header="记录号" Width="50" DisplayMemberBinding="{Binding Path=记录号}"   />
                    <GridViewColumn Header="购买时间" Width="70" DisplayMemberBinding="{Binding Path=购买时间}" />
                    <GridViewColumn Header="所购物品清单" Width="200" DisplayMemberBinding="{Binding Path=所购物品清单}" />
                    <GridViewColumn Header="共用费用（元）" Width="100" DisplayMemberBinding="{Binding Path=共用费用（元）}" />
                </GridView>
            </ListView.View>
        </ListView>
我的数据是从数据库中来，现在我把数据显示在ListView中，我想获得其中Header="所购物品清单"的全部值。请教高手

遍历数据源，再用集合存储全部值
