目前我正在开发一个应用程序，并希望添加一个Windows (7) JumpList。我遵循了几个教程并研究了文档，但我不知道如何完成这项工作。简而言之:我需要最近一次选择文件的列表。所以在关闭应用程序后，用户可以很容易地用我的应用程序打开最近的文件。我已经实现了一些文件关联机制。
是否有可能分享一些代码/教程，我如何能解决上述问题?
提前感谢!
*我已经尝试了接下来的几个项目/教程:
- http://www.codeproject.com/Articles/103913/How-to-Create-a-Custom-Jumplist-with-Custom-Events
- http://channel9.msdn.com/coding4fun/articles/Windows-7-Jump-Lists
- http://csharp-tricks-en.blogspot.nl/2011/10/create-jumplist-using-c.html
* Coding 4 Fun的代码可以工作，但是我不知道如何开发一个最近的文件列表
您可以查看这篇文章。而不是在WPF中显示结果，您需要在jumplist中显示结果。
为什么不试着将最近打开的文件名存储在数据库或xml文件中，然后读取它来设置跳转列表呢?
private void ReportUsage()
{
XmlDocument myXml = new XmlDocument();
myXml.Load(historyXml);
string list = historyXml;
jumpList.ClearAllUserTasks();
foreach (XmlElement el in myXml.DocumentElement.ChildNodes)
{
string s = el.GetAttribute("url");
JumpListLink jll = new JumpListLink(Assembly.GetEntryAssembly().Location, s);
jll.IconReference = new IconReference(Path.Combine("C:\Program Files\ACS Digital Media\TOC WPF Browser\Icon1.ico"), 0);
jll.Arguments = el.GetAttribute("url");
jumpList.AddUserTasks(jll);
}
jumpList.Refresh();
}
或者初学者的解决方案是将所有文件路径保留到给定最大容量的Queue中，并在运行时将它们添加到menuItem中。对不起，我没有时间写完整的代码
正如第二篇文章中所描述的，您的应用程序必须注册为目标文件扩展名的处理程序，否则将不会显示您的Jumplist最近的类别。你可以在这里找到更多关于文件关联注册的详细信息。
您可以手动注册您的应用程序，但您需要管理员权限，所以不建议这样做，或者为您的应用程序创建一个安装项目，如编码4乐趣文章中所述，或者您可以让用户关联文件扩展名。
这是一个在Windows 7下工作的示例，无需注册，只需右键单击我想要加载的文本文件并选择"打开"并浏览到我的应用程序。
示例需要Windows API代码包public partial class Form1 : Form
{
[STAThread]
static void Main(string[] args)
{
var file = args != null && args.Length > 0 ? args[0] : string.Empty;
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1(file));
}
public Form1()
: this(string.Empty)
{
}
public Form1(string file)
{
InitializeComponent();
Open(file);
}
