    { 
     // 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 documents (.txt)|*.txt"; 

     // Display OpenFileDialog by calling ShowDialog method 
     Nullable<bool> result = dlg.ShowDialog(); 

     // Get the selected file name and display in a TextBox 
     if (result == true) 
     { 
      // Open document 
      string filename = dlg.FileName; 
      FileNameTextBox.Text = filename; 

      Paragraph paragraph = new Paragraph(); 
      paragraph.Inlines.Add(System.IO.File.ReadAllText(filename)); 
      FlowDocument document = new FlowDocument(paragraph); 
      FlowDocReader.Document = document; 
     } 
    }

您可以在Microsoft.Office.Interop.Word命名空间中使用类或另一个图书馆。我会建议DocX library。该库是轻量级的，最重要的是不需要安装Office Word。

using Novacode; 
// ... 
private void button1_Click(object sender, RoutedEventArgs e) 
{ 
    // Create OpenFileDialog 
    Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog(); 

    // Set filter for file extension and default file extension 
    dlg.DefaultExt = ".doc"; 
    dlg.Filter = "Word documents|*.doc;*.docx"; 

    // Display OpenFileDialog by calling ShowDialog method 
    Nullable<bool> result = dlg.ShowDialog(); 

    // Get the selected file name and display in a TextBox 
    if (result == true) 
    { 
     // Open document 
     string filename = dlg.FileName; 
     FileNameTextBox.Text = filename; 

     var document = DocX.Load(filename); 

     string contents = document.Text; 

     // Use the file 
    } 
}
