摘要：
做项目时，我需要分页数据。我在网站上搜索了很长时间，但仍然找不到合适的。我自己不会写。我急于先写这个项目，有时间我会重写它。页面部分代码˃背景代码：usingSystem；usingSystem.Collections.Generic；usingSystem.Linq；usingSystem.Text；usingSystem。Windows；usingSystems。Windows.Controls；using System。Windows.Data；using Systems。Windows.Documents；using System.Windows.Input；using System.Windows.Media；using system.Windows.Media.Imageing；using系统.Windows.导航；usingSystem.窗口。形状；namespaceT测试｛publicdelegatevoidPagerIndexChangingEvent；/////Pager.xaml/////publicpartialclassPager:UserControl｛publicPager（）｛InitializeComponent（）；｝publiceventPagerIndexChangingEventPageIndexChanging；///////当前页面的索引////privateintpageIndex=0；publicintPageIndex｛get｛returnpageIndex；｝设置｛pageIndex＝value；｝｝//////总页数///privateintpageCount///////页数///privateintpageSize=12；publicintPageSize｛get｛returnpageSize；｝设置｛pageSize=value；｝｝//数据私有计数的数量；publicintCount｛get｛returncount；｝设置｛count＝value；ifpageCount＝0；elsepageCount＝count%pageSize＝＝0？

做项目时需要数据分页在网站找了半天也没有找到合适的，没办法自己写个，项目比较着急先凑合写个吧,有时间在重写下。
