如何将本地（非在线）帮助集成到WPF应用程序中？这更像是一本手册，但我希望以某种方式将其集成。
编辑：刚刚发现http://wordtoxaml.codeplex.com，我会尝试使用它。它可以将Word文档转换为XAML，然后我可以在WPF中显示。
编辑2：我找到了一个可行的解决方案：在Word中编写手册，另存为XPS格式，并使用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。
我们使用RoboHelp并生成chm文件，有时也称为HTML帮助文件。.NET Framework的Help类有一个方法ShowHelp，您可以调用它，并传递chm文件和要显示的主题。您可以按主题标题、ID等方式进行显示。我们使用主题标题进行显示，因此调用看起来像这样：
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，该类创建了一个名为HelpTopic的附加属性。这使您可以将HelpTopic属性附加到任何FrameworkElement上。该类还使用静态构造函数将内置的F1帮助命令挂钩到命令处理程序上，以从源中检索附加属性并打开帮助文档。

有了这个设置，你可以像这样从代码中调用帮助文档:
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Windows或任何元素上按F1时，他们将获得上下文相关的帮助。
我有类似的需求，但我只需要将F1键与我们现有的帮助代码连接起来。
最终我从大约5个不同的StackOverflow页面中提取了一些混合内容，因此我在这里发布以便其他人有类似的需求时能够使用。
在我的MainWindow.xaml中，我添加了一个KeyBinding到inputBindings中，将F1键连接到一个ICommand：
<Window.InputBindings>
(other bindings here...)
<KeyBinding Key="F1" Command="{Binding Path=ShowHelpCommand}"/>
</Window.InputBindings>
然后在我的MainWindowViewModel.cs中，我添加了这个ICommand，它调用了我现有的Help代码。
private ICommand _showHelpCommand;
public ICommand ShowHelpCommand
{
get
{
return _showHelpCommand ??
(_showHelpCommand = new RelayCommand(p => DisplayCREHelp(), p => true));
}
}
RelayCommand()和DisplayCREHelp()是什么？ - InteXX
