WFP: 读取XPS文件或将word、txt文件转化为XPS文件
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"

<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>
