近期库房想在出库存放区划分货位存放不同客户拣货后的商品数据。
同时需要在货位摆放屏幕以便显示当前货位被那个客户拣货占用，及商品信息、拣货状态等

由于独立项目，数据来源于api接口，所以只是一个客户端轮播即可。故拿wpf来试试demo

设计为：

1、一个主界面为控制台控制第2,3,....屏显示不同客户（货位）的信息去请求不同的数据

2、第2、3...屏的轮播数据展示

实现：

1、创建项目net下都一致，略过

2、控制不同屏幕轮播不同信息，只需要相关配置即可，这里略过

3、显示轮播信息这里使用一个按钮跳转来完成

<Button  Grid.Column="2" Content="滚动" Name="btn_scroll" Width="100" Click="btn_Scroll_Click"/>

跳转到次屏

private void btn_Scroll_Click(object sender, RoutedEventArgs e)
        {
            ScrollWindow w = new ScrollWindow();
            MultipScreenManager.ShowInScreen(w);
        }

这里使用到一个主次屏管理，引用了某一位博主（当前忘记了是哪一位，有知道的通知我补登）的MultipScreenManager

注意点：
让次屏全屏显示时让width、height=获取到的屏幕大小

开启timer设置间隔时间轮播，默认从第一页开始，设定每屏幕可轮播的行数，到最后一页后重新从第一页轮播

也可以开启鼠标经过轮播体时暂停，离开时继续：MouseEnter="ScrollWindow_MouseEnter" MouseLeave="ScrollWindow_MouseLeave"

Storyboard的DoubleAnimation设置属性控制进入轮播的进入效果及位置等

需要ui好看点，可以引入皮肤库，这这里使用了：MaterialDesign 

只需要在app.xaml中增加配置：

<Application.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Light.xaml"></ResourceDictionary>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignThemes.Wpf;component/Themes/MaterialDesignTheme.Defaults.xaml" ></ResourceDictionary>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Primary/MaterialDesignColor.DeepPurple.xaml"></ResourceDictionary>
                <ResourceDictionary Source="pack://application:,,,/MaterialDesignColors;component/Themes/Recommended/Accent/MaterialDesignColor.Lime.xaml"></ResourceDictionary>
            </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Application.Resources>

然后在使用页面引入：xmlns:materialDesign="http://materialdesigninxaml.net/winfx/xaml/themes"
