3. Asp.Net 程序顯示錯誤如下: Server Error in '/' Application. Runtime Error Description: An application error occurred on the server. The current custom error settings for this application prevent the details of the application error from being viewed remotely (for security reasons). It could, however, be viewed by browsers running on the local server machine. Details: To enable the details of this specific error message to be viewable on remote machines, please create a <customErrors> tag within a "web.config" configuration file located in the root directory of the current web application. This <customErrors> tag should then have its "mode" attribute set to "Off". 原因1: web.config 文件不完整.不是合格的asp.net 配置文件. 解決: 您要檢查web.config 是否合格,有時候是粗心,xml文件不完整.導致的問題 原因2: asp.net版本問題.asp.net有asp.net 1.1和 asp.net2.0 兩個版本.
