编程明确的Silverlight应用程序存储？ [英] Programmatically clear Silverlight Application Storage?

问题描述

我发表了一些客户的Silverlight应用程序。我有问题发布更新。

I have a Silverlight app published for some customers. I am having problems issuing updates.

我想，当一个用户加载的网页开始，如果他们的应用程序存储容量超过上一次的网站更新，那么<一个href="http://www.softcity.com/article/internet-networking/sneaky-silverlight-and-isolated-storage-another-bad-batch-of-cookies/wN2gTMwADN"相对=nofollow>这个发生。这将使我的申请工作。

I would like for when a user loads the webpage initially, if their Application Storage is older than the last time the site was updated, then this happens. This will make my application work.

于是，两个问题：

• 我如何检查是否用户存储的应用程序存储容量超过 最后更新Silverlight的网站？

• How can I check if the users stored Application Storage is older than the last update to the Silverlight site?

如何删除应用程序存储的网站？

How can I delete the Application Storage for the site ?

我已经打过电话：

using( var store = IsolatedStorageFile.GetUserStoreForApplication() ) {
  store.Remove();
}
using( var store = IsolatedStorageFile.GetUserStoreForSite()) {
  store.Remove();
}

在 App.xaml.cs 文件，但这些似乎都在显示的页面上没有任何影响 - 应用程序存储没有完全清除。

in the App.xaml.cs file, but these seem to have no effect on the displayed page - the Application Storage is not fully cleared.

推荐答案

•我如何检查是否存储了用户的应用程序存储早于上次更新Silverlight的网站？

•How can I check if the users stored Application Storage is older than the last update to the Silverlight site?

这code进去的应用程序，以检查是否有和更新您的SL应用程序，我不知道这是否帮助，但如果你只是想要做的事与IsolatedStorageFile当有更新它应该是你想要什么：

this code go in app to check if there's and update to your SL application I don't know if it help but if you just want to do something with that IsolatedStorageFile when there's update it should be what you want :

Application.Current.CheckAndDownloadUpdateAsync();
Application.Current.CheckAndDownloadUpdateCompleted += new CheckAndDownloadUpdateCompletedEventHandler(Current_CheckAndDownloadUpdateCompleted);

private void Current_CheckAndDownloadUpdateCompleted(object sender, CheckAndDownloadUpdateCompletedEventArgs e)
{   
   if (e.UpdateAvailable) 
   { 

   } 
}
