在System.Data.Linq.dll中發生類型爲「System.Data.SqlServerCe.SqlCeException」的未處理的異常

我收到以下錯誤，我不知道爲什麼，因爲我的應用程序在4小時前正常運行，但現在不工作，我並沒有改變任何東西..在System.Data.Linq.dll中發生類型爲「System.Data.SqlServerCe.SqlCeException」的未處理的異常

的類型「System.Data.SqlServerCe.SqlCeException」未處理的異常出現在 System.Data.Linq.dll

我得到錯誤在行db.SubmitChanges(); ..我離開下面的完整代碼。

通常，例外情況也包括消息。是否有任何其他信息與錯誤一起提供？ – 2015-02-07 00:04:44

沒有消息和/或內部異常，任何人都很難幫助你。 – 2015-02-07 00:17:16

其實沒有其他信息。我可以顯示問題的圖像，但我不知道如何在此處添加圖像。 – 2015-02-07 00:41:36

好吧，我不知道爲什麼，但現在我的應用程序正在工作。我認爲這個錯誤是Visual Studio中的一種錯誤，因此，爲了解決我的問題，我重新啓動了我的電腦。

難道你不打電話給技術支持？你有沒有嘗試重新啓動你的電腦？ – THBBFT 2015-02-17 14:40:42

要去上肢體這裏根據以往的經驗。 SqlServerCE驅動程序有兩種風格，x86和x64。通常，只有一個可以安裝在機器上，安裝程序會在第二個上失敗。但是，如果首先安裝x86驅動程序然後安裝x64，則可以在命令行上使用/ force開關。

這可能會幫助你的問題，或者它可能很難從所提供的細節中分辨出來。

這是Windows Phone，運行ARM操作系統，沒有任何可安裝的驅動程序。 – 2015-02-07 03:04:01

所以它沒有讀取代碼。 – THBBFT 2015-02-07 03:06:11
