在 WPF 应用程序中集成本地（而不是在线）帮助的可能方法是什么？它更像是一本手册，但我想以某种方式整合它。
编辑：刚刚找到http://wordtoxaml.codeplex.com，我会试试那个。它将 word 文档转换为 xaml，我可以在 WPF 中显示。
编辑 2：我找到了一个可行的解决方案：用 word 编写手册，另存为 XPS，然后使用 https://web.archive.org/web/20111116005415/http://www.umutluoglu.com/english/post/2008/12/20/Showing-XPS-Documents-with-DocumentViewer-Control-in-WPF.aspx 显示它
【问题讨论】：
我们使用 RoboHelp 并生成一个 chm 文件，有时也称为 HTML 帮助文件。 .NET Framework 的Help 类有一个您调用的方法ShowHelp，传递chm 文件和您要显示的主题。您可以告诉它按主题标题、ID 等显示。我们使用主题标题显示，因此调用如下所示：
System.Windows.Forms.Help.ShowHelp(null, "Help/ExiaProcess.chm", HelpNavigator.Topic, helpTopic);
接下来，您可以创建一个名为 HelpProvider 的类，该类创建一个名为 HelpTopic 的附加属性。这允许您将 HelpTopic 属性附加到任何 FrameworkElement。该类还使用静态构造函数将内置 F1 帮助命令挂钩到命令处理程序，这些处理程序从源中检索附加属性并打开帮助。

有了这些，您可以通过如下代码调用您的帮助：
private void HelpButton_Click(object sender, RoutedEventArgs e)
{
Help.HelpProvider.ShowHelpTopic("License Key Dialog");
}
更好的是，现在您可以像这样将帮助附加到 UI 中的任何 FrameworkElement，
<Window name="MainWin"
...
...
xmlns:help="clr-namespace:ExiaProcess.UI.Help"
...
...
help:HelpProvider.HelpTopic="Welcome to YourApp" />
...
...
<TextBox help:HelpProvider.HelpTopic="Bug Title" />
...
...
<ComboBox help:HelpProvider.HelpTopic="User Drop Down"/>
...
现在，当用户在窗口或任何元素上按 F1 时，他们将获得上下文相关的帮助。
【讨论】：
我也有类似的需求，只是我只需要将 F1 键连接到我们现有的帮助代码。
我最终提取了大约 5 个不同的 StackOverflow 页面，所以我把它放在这里以防其他人有类似的需求。
在我的 MainWindow.xaml 中，我在 inputBindings 中添加了一个 KeyBinding 以将 F1 连接到 ICommand：
<Window.InputBindings>
(other bindings here...)
<KeyBinding Key="F1" Command="{Binding Path=ShowHelpCommand}"/>
</Window.InputBindings>
然后在我的 MainWindowViewModel.cs 中添加了这个调用我现有帮助代码的 ICommand。
private ICommand _showHelpCommand;
public ICommand ShowHelpCommand
{
get
{
return _showHelpCommand ??
(_showHelpCommand = new RelayCommand(p => DisplayCREHelp(), p => true));
}
}
我希望这对遇到类似问题的人有所帮助。

RelayCommand() 和 DisplayCREHelp() 是什么？
