mscorlib異常

任何人都可以告訴我什麼是錯誤的基於以下異常我的web應用程序？當我嘗試從VS2008運行此項目時遇到此問題：mscorlib異常

System.Security.SecurityException was unhandled

你可以顯示異常時運行的線程的代碼嗎？我可以看到一些窗口正在顯示/調用這是一個WPF是否正確？由於某種原因，該窗口觸發了權限異常...還有該窗口的代碼以及請... – t0mm13b 2010-03-04 16:57:49

如何在異常時運行代碼？我看到的是：步驟爲：跨過非用戶代碼「XamlGeneratedNamespace.GeneratedApplication.InitializeComponent」步驟爲：步進比非用戶代碼「XamlGeneratedNamespace.GeneratedApplication.GeneratedApplication」步驟爲：步進比非用戶代碼「XamlGeneratedNamespace.GeneratedApplication.InitializeComponent」步驟爲：步進比非用戶代碼「XamlGeneratedNamespace.GeneratedApplication.GeneratedApplication」步驟爲：步進比非用戶code'XamlGeneratedNamespace.GeneratedApplication.InitializeComponent」 – salvationishere 2010-03-04 19:07:48

我很驚訝，這是在正常的Web應用程序的xaml附近。你確定這不是一個WPF/Silverlight應用程序嗎？ – 2010-03-04 21:39:14

查看是否有執行非託管代碼權限...如果沒有，授予它，然後再試一次...

我認爲這是要在您的規則arsed了對一些設置原因...

我該怎麼做？我發現一個鏈接描述如何使用以下代碼執行此操作，但我正在尋找更簡單的解決方案： http://msdn.microsoft.com/en-us/library/d0313z05.aspx – salvationishere 2010-03-04 19:00:37

開始>控制面板>管理工具> Microsoft .Net Framework配置。看看執行策略 - 似乎有一個「運行非託管代碼」部分 - 不知道如何編輯它 - 只是嘗試和失敗自己... – 2010-03-04 21:38:00

謝謝你的迴應！我在運行時安全策略的權限集下的多個位置找到了「執行」選項卡。但所有這些都是隻讀的。對於所有這些都設置爲「否」。如何編輯權限集？ – salvationishere 2010-03-04 21:50:08
