在win8中使用c#从开始菜单取消固定

我正在开发一个c#桌面应用程序。

我们需要根据条件数取消固定应用程序磁贴。这可能发生在应用程序生命周期的任何时间,而不仅仅是在安装过程中。

我看到了this关于如何在CPP中取消固定拼贴的问题。我也尝试在C#中做到这一点但没有成功。

任何帮助?

我能够编写一个C#代码,将AppUserModel_StartPinOption设置为APPUSERMODEL_STARTPINOPTION_NOPINONINSTALL,但它没有帮助:(

这是代码:

private static void InstallShortcut(string linkPath)
    {

        // Find the path to the current executable
        // String exePath = Process.GetCurrentProcess().MainModule.FileName;  //Path to the current exe file that is running.  C:\\...
        IShellLinkW newShortcut = (IShellLinkW)new CShellLink();

        // Create a shortcut to the exe
        ErrorHelper.VerifySucceeded(newShortcut.SetPath(targetPath));
       ErrorHelper.VerifySucceeded(newShortcut.SetArguments(""));

        // Open the shortcut property store, set the AppUserModelId property
        IPropertyStore newShortcutProperties = (IPropertyStore)newShortcut;


            var APPUSERMODEL_STARTPINOPTION_NOPINONINSTALL = new PropVariant(0);
            var StartPinOption = new PropertyKey(new Guid("{9F4C2855-9F79-4B39-A8D0-E1D42DE1D5F3}"), 12);
            ErrorHelper.VerifySucceeded(newShortcutProperties.SetValue(StartPinOption, APPUSERMODEL_STARTPINOPTION_NOPINONINSTALL));


            ErrorHelper.VerifySucceeded(newShortcutProperties.Commit());


        // Commit the shortcut to disk
        IPersistFile newShortcutSave = (IPersistFile)newShortcut;

        ErrorHelper.VerifySucceeded(newShortcutSave.Save(linkPath, true));
    }

我尝试了两种方法:删除磁贴,然后重新创建它,并更改现有磁贴的参数,但没有任何效果,磁贴仍然固定在开始菜单上。

您是在谈论主应用磁贴还是辅助磁贴?如果您指的是辅助磁贴,则可以在this article中找到取消固定的示例代码。它的核心是(为了简单起见我修改了一下;请参阅文章了解完整代码):

 // Check to see if this restaurant exists as a secondary tile and then unpin it
 string restaurantKey = this.m_ViewModel.Restaurant.Key;
 Button button = sender as Button;
 if (button != null)
 {
     if (Windows.UI.StartScreen.SecondaryTile.Exists(restaurantKey))
     {
         SecondaryTile secondaryTile = new SecondaryTile(restaurantKey);
         bool isUnpinned = await secondaryTile.RequestDeleteForSelectionAsync(GetElementRect((FrameworkElement)sender), Windows.UI.Popups.Placement.Above);

         if (!isUnpinned)
         {
             // Do error handling here
         }
     }
     else
     {
         // If we ever get to this point, something went wrong or the user manually 
         // removed the tile from their Start screen.  
         Debug.WriteLine(restaurantKey + " is not currently pinned.");
     }
 }

根据the MSDN article: System.AppUserModel.StartPinOption (Windows),No pin install选项应为(1)

var APPUSERMODEL_STARTPINOPTION_NOPINONINSTALL = new PropVariant(1);

我这样做了。
