我正在构建一个使用隔离存储的 Windows Phone 7 应用程序。该代码大部分时间都有效,但我不断随机收到 IsolatedStorageExceptions:
{"An error occurred while accessing IsolatedStorage."}
There are no further details about the reason for the exception. Here is the stack trace:
at System.IO.IsolatedStorage.IsolatedStorageFile.DeleteFile(String file)
at MyApp.Core.Data.WindowsPhoneFileRepository.DeleteFile(String name)
at MyApp.Core.Domain.ThingService.SaveThing(Thing Thing)
at MyApp.Core.Domain.TrackedThingService.PersistThingLocally(TrackedThing Thing)

at System.Windows.Interactivity.EventTriggerBase.OnEvent(EventArgs eventArgs)
at System.Windows.Interactivity.EventTriggerBase.OnEventImpl(Object sender, EventArgs eventArgs)
at System.Windows.Controls.Primitives.ButtonBase.OnClick()
at System.Windows.Controls.Button.OnClick()
at System.Windows.Controls.Primitives.ButtonBase.OnMouseLeftButtonUp(MouseButtonEventArgs e)
at System.Windows.Controls.Control.OnMouseLeftButtonUp(Control ctrl, EventArgs e)
at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)
该文件存在。我将所有的 IsolatedStorage 使用都放在 using 块中,所以我不应该在任何地方打开文件。
这可能是什么原因造成的?
如何获得有关异常原因的更多详细信息?
