WPF 读取Docx文件并显示(附下载链接)

在wpf中直接显示Docx文件 ，直接看看效果吧：

下面直接看代码，添加主要有两个类：

DocxReader类：

}

，最后，在MainWindow.xaml代码：

<Window x:Class="WpfEmbeddedDocx.MainWindow"xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"xmlns:d="http://schemas.microsoft.com/expression/blend/2008"xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"xmlns:local="clr-namespace:WpfEmbeddedDocx"mc:Ignorable="d"Title="MainWindow" Height="450" Width="800"><Grid><DockPanel><Menu DockPanel.Dock="Top"><MenuItem Header="_Open file..." Click="OnOpenFileClicked"/></Menu><FlowDocumentScrollViewer Name="FlowDocumentScrollViewer"></FlowDocumentScrollViewer></DockPanel></Grid>
</Window>

MainWindow.cs的代码：

using System.IO;
using System.Windows;
using System.Windows.Controls;
using Microsoft.Win32;namespace WpfEmbeddedDocx
{public partial class MainWindow : Window{public MainWindow(){InitializeComponent();}private void ReadDocx(string path){using (var stream = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite)){var flowDocumentConverter = new DocxToFlowDocumentConverter(stream);flowDocumentConverter.Read();FlowDocumentScrollViewer.Document = flowDocumentConverter.Document;this.Title = Path.GetFileName(path);}}private void OnOpenFileClicked(object sender, RoutedEventArgs e){var openFileDialog = new OpenFileDialog(){DefaultExt = ".docx",Filter = "Word documents (.docx)|*.docx"};if (openFileDialog.ShowDialog() == true)this.ReadDocx(openFileDialog.FileName);}}
}

这样就能实现视频中的效果啦。。
