如何使用C＃中的DocumentFlowReader在一列中顯示簡單的txt文件中的文本WPF

Question

我正在使用DocumentFlowReader顯示txt文件中的文本。一切工作正常，但是當我全屏顯示我的文本分成幾列時，如何僅在一個列中顯示它？

這裏是我的代碼：

XAML文件：

<DockPanel> 
      <Menu DockPanel.Dock="Top"> 
       <MenuItem Header="_File"> 
        <MenuItem x:Name="OpenFile" Header="_Open" Click="OpenFile_Click" /> 
        <Separator /> 
        <MenuItem Header="_Exit" />     
       </MenuItem>       
      </Menu> 
      <TextBlock x:Name="txtCurrentPage" DockPanel.Dock="Bottom" TextAlignment="Center" Background="LightYellow"> 
       Current page: 
      </TextBlock> 
      <DockPanel DockPanel.Dock="Left"> 
       <TextBlock DockPanel.Dock="Top">Your books</TextBlock> 
       <ListView DockPanel.Dock="Left" x:Name="listboxBooks" Grid.Row="1" BorderThickness="0" ItemsSource="{Binding}" PreviewMouseDoubleClick="listboxBooks_PreviewMouseDoubleClick"> 
        <ListView.View> 
         <GridView> 
          <GridViewColumn Header="Name" Width="120" DisplayMemberBinding="{Binding name}" /> 
          <GridViewColumn Header="Finished" Width="120" DisplayMemberBinding="{Binding readBook}" /> 
         </GridView> 
        </ListView.View> 
       </ListView> 
      </DockPanel> 

      <TextBlock DockPanel.Dock="Right" Background="Bisque"> 
       <Button x:Name="btnPreviousPage" Click="btnPreviousPage_Click" >Previous Page</Button> 
       <Button x:Name="btnNextPage" Click="btnNextPage_Click">Next Page</Button> 
       <Button x:Name="btnSavePage" Click="btnSavePage_Click" >Save Page</Button> 
      </TextBlock> 
      <FlowDocumentReader Name="FlowDocReader" Background="LightBlue"> 

      </FlowDocumentReader> 
     </DockPanel> 

這是我如何讀取文件中的文本：

// Create OpenFileDialog 
Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog(); 

// Set filter for file extension and default file extension 
dlg.DefaultExt = ".txt"; 
dlg.Filter = "Text Files (*.txt)|*.txt"; 

string filename = dlg.FileName; 

Paragraph paragraph = new Paragraph(); 

paragraph.Inlines.Add(System.IO.File.ReadAllText(filename)); 

FlowDocument document = new FlowDocument(paragraph); 

FlowDocReader.Document = document; 

此代碼做的不錯，它正在讀數據並顯示它，但是當窗口全屏時，它會在幾列中顯示文本。即使在窗口全屏的情況下，我也只想顯示它。我怎樣才能做到這一點？

Answer 1

將ColumnWidth屬性設置爲足夠大的屏幕。

FlowDocument document = new FlowDocument(paragraph); 
document.ColumnWidth = 2000; //or carefully calculate a proper value 
FlowDocReader.Document = document;
