为什么删除上传的文件时出错？

错误提示如下：
Server Error in '/Recruitment' 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".



<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.



<configuration>
    <system.web>
        <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
    </system.web>
</configuration>

--------------------编程问答-------------------- 程序有问题,是那里有问题,现暂看不出来
现你只有按错误的提示来做:
到web.config文件,把 <customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>
改为<customErrors mode="Off"/>
然后再run,这时错误应该显示出来了.到时再看看是什么错误,而做出相应的修正.
