字符串b=listBox1.SelectedItem.ToString（）；
MessageBox.Show（b）

我真的建议你使用。它有一个
DatePicker
控件

    <ListBox Height="56" HorizontalAlignment="Left" Margin="243,171,0,0" Name="listBox1" VerticalAlignment="Top" Width="207">
            <ListBoxItem Content="01" HorizontalContentAlignment="Center" IsSelected="True" VerticalContentAlignment="Center" FontSize="32" FontWeight="Bold" FontFamily="Segoe WP Bold" BorderThickness="5" />
            <ListBoxItem Content="02" HorizontalContentAlignment="Center" IsSelected="True" VerticalContentAlignment="Center" FontSize="32" FontWeight="Bold" FontFamily="Segoe WP Bold" BorderThickness="5"/>
            <ListBoxItem Content="03" HorizontalContentAlignment="Center" IsSelected="True" VerticalContentAlignment="Center" FontSize="32" FontWeight="Bold" FontFamily="Segoe WP Bold" BorderThickness="5" />
            <ListBoxItem Content="04" HorizontalContentAlignment="Center" IsSelected="True" VerticalContentAlignment="Center" FontSize="32" FontWeight="Bold" FontFamily="Segoe WP Bold" BorderThickness="5" />
            <ListBoxItem Content="05" HorizontalContentAlignment="Center" IsSelected="True" VerticalContentAlignment="Center" FontSize="32" FontWeight="Bold" FontFamily="Segoe WP Bold" BorderThickness="5" />

    </ListBox>
如果您真的想使用自己的
组合框
控件，我建议您至少使用C#中可用的
日期时间
类型，以简化操作。

是的，使用toolkit控件。 
    <ListBox Height="56" HorizontalAlignment="Left" Margin="243,171,0,0" Name="listBox1" VerticalAlignment="Top" Width="207">
