读取XPS格式文件或将doc，txt文件转化为XPS文件，效果图如下：
1.XAML页面代码：
<Window x:Class="WpfWord.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"Title="WordReader" Height="500" Width="900"><Grid><Grid.RowDefinitions><RowDefinition/></Grid.RowDefinitions><Grid.ColumnDefinitions><ColumnDefinition Width="0" Name="cdTree"/><ColumnDefinition Width="auto"/><ColumnDefinition Width="3*"/></Grid.ColumnDefinitions><GroupBox Header="导航目录"><TreeView Name="tvTree" SelectedItemChanged="tvTree_SelectedItemChanged"/></GroupBox><GridSplitter Width="3" ResizeBehavior="PreviousAndNext" Grid.Column="1" Background="LightGray"/><Grid Grid.Column="3"><Grid.RowDefinitions><RowDefinition Height="auto"/><RowDefinition Height="*"/></Grid.RowDefinitions><DocumentViewer Name="dvShow" Grid.Row="1"/><StackPanel Grid.Row="0" Orientation="Horizontal" HorizontalAlignment="Right"><CheckBox Content="显示导航" Height="16" Margin="5" Name="cbNav" Width="75" Click="cbNav_Click" /><Label Content="页面"/><Label Name="lblCurPage" Margin="0"/><Label Name="lblPage"/><Button Content="上一页" Height="23" Name="btnPrev" Width="75" Click="btnPrev_Click" /><Button Content="下一页" Height="23" Name="btnNext" Width="75" Click="btnNext_Click" /><Label Content="总字数:" Name="lblWordCount"/></StackPanel></Grid></Grid> </Window>
2.后台CS文件代码：
