这是我的 wpf 文件。我希望GridView支持多项选择。

            <ListView Name="deviceListBox"
                  Width="630"
                  Height="282"
                  HorizontalAlignment="Center"
                  VerticalAlignment="Center"
                  ItemsSource="{Binding Items}"
                  SelectionChanged="deviceListBox_SelectionChanged"
                  SelectionMode="Single">
            <ListView.View>
                <GridView>
                    <GridView.Columns>
                        <GridViewColumn>
                            <GridViewColumn.HeaderTemplate>
