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 ".
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode= "Off "/>
</system.web>
</configuration>
Notes: The current error page you are seeing can be replaced by a custom error page by modifying the "defaultRedirect " attribute of the application 's <customErrors> configuration tag to point to a custom error page URL.
<!-- Web.Config Configuration File -->
<configuration>
<system.web>
<customErrors mode= "RemoteOnly " defaultRedirect= "mycustompage.htm "/>
</system.web>
</configuration>
我把服务器修改好的问题覆盖了一下（覆盖的不是config文件，是一个普通的cs文件）以上是错误信息~~ 求高手看
------解决方案--------------------------------------------------------
修改为 customErrors mode= "Off "这样可看到详细信息.
