事件日誌有錯誤。「發生了未處理的異常」

我正在使用Visual Studio 2005和IIS 6.0 ..我在事件日誌中有此警告。我試圖找到它是什麼。當我工作時，我從來沒有經歷過這個例外。可以做些什麼以及在哪裏可以做到不再發生異常警告。提前感謝！事件日誌有錯誤。「發生了未處理的異常」

您可以粘貼UserTownPage.Page_Load的代碼嗎？ – 2010-10-19 15:18:32

在web.config中啓用調試編譯，這將確保您會看到在什麼行上引發異常 – Onkelborg 2010-10-19 15:22:19

謝謝所有人的關注！我用Pageload（）和函數調用了它的問題。如果您需要其他信息，請告訴我。 – Ram 2010-10-19 15:56:43

這個問題似乎是NullReferenceException被拋出insed的UserTownPage類型的Page_Load方法。不止如此，不能從所提供的信息中確定。

你需要做的是調試到該方法，並確切地看到空引用發生的位置。
