求救高手:Server Error in '/aaa' Application.解决立即给分!

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-------------------- 配置文件改为
<configuration>
    <system.web>
        <customErrors mode="Off"/>
    </system.web>
</configuration> --------------------编程问答-------------------- 把 customErrors mode="RemoteOnly"
设为 customErrors mode="Off" 看看错误是什么 --------------------编程问答-------------------- 学习 --------------------编程问答-------------------- 先看详细错误,再对症下药.
--------------------编程问答-------------------- 把 customErrors mode="RemoteOnly"
改为 customErrors mode="Off"
允许调试信息
<compilation
         defaultLanguage="c#"
         debug="true"
    />

编译程序使用Debug --------------------编程问答-------------------- 按net_lover(【孟子E章】)的方法设置后出现:

--------------------编程问答-------------------- 调用com组件是出错.
--------------------编程问答-------------------- Web.config 问题

我刚刚也遇到这个问题了，用一个新的Web.config替换就没有问题了。

我后来仔细对了对没有发现太大的差别。注意下面的权限问题

    <authorization>
        <allow users="*" /> 
            
    </authorization>
