從Silverlight 4升級到導致AccessViolationException的Silverlight 5

Question

我們已將項目從Silverlight 4升級到Silverlight 5，現在我們不時在代碼中的不同位置遇到 AccessViolationException，此異常還會導致瀏覽器崩潰。

有沒有任何指導方針如何防止這種情況發生？

我加入其中AccessViolationException被彈出堆棧跟蹤：

Answer 1

我的猜測是它要麼是一個錯誤的運行時安裝，或瀏覽器插件或殺毒軟件。

疑難解答這樣說：

1. 是什麼DrWatson日誌顯示？苔絲費蘭德斯有很多關於如何閱讀崩潰日誌的信息。或者在這裏發佈你的崩潰日誌。
2. 這是否發生在不同的瀏覽器？
3. 你可以關閉任何插件嗎？
4. 這是否發生在所有計算機上？
5. 您的應用程序是否使用任何COM自動化或PInvoke？

Answer 2

我發現問題的一個來源（我不確定它解決了所有這些AccessViolationException問題），但我的系統現在更加穩定。

顯然使用局黑色主題，從最新的工具包，與文本框的組合，導致出現此問題。

我做了什麼來解決這個問題是重新編譯這個主題沒有文本框和AccessViolation問題的方式已經消失，在這個階段，我們沒有做對整個系統的測試深，但是這是解決了我可以快速複製的問題，所以我認爲這可能會解決更多問題。

希望它幫助了某人。

問候，

Answer 3

好吧，我已經找到了解決辦法。之前，我在Mainpage.xaml文件中設置了整體應用程序樣式/主題，並且主題在運行時反映到所有子導航頁面。這是以某種方式造成問題的原因。

如果我在頁面上明確設置樣式 - 一切正常！

因此：（使用BureauBlue工具箱主題）

xmlns:SystemColors="clr-namespace:System.Windows.Controls.Theming;  assembly=System.Windows.Controls.Theming.BureauBlue" 

<SystemColors:BureauBlueTheme> 
    <Grid x:Name="LayoutRoot"> 

。 。 。

Answer 4

使用Bureau Blue在更新綁定到文本框的屬性時也會導致相同的System.AccessViolationException異常。

對我而言，解決方法是將TextBox樣式從Theme dll複製到合併到App.xaml資源字典中的ResourceDictionary中。這樣做避免了必須在每個視圖上指定主題。

我使用的主題來自2010年4月的工具包。我不知道以後的工具包版本是否可以解決問題。
