Runtime Error 问题

[yanxiang23]

小弟维护一个网站，最近突然出现一个问题，在网站上传一些更新内容之后，偶尔几次还好，多上传几次之后网站页面就出现了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>



求教各位大虾该如何解决啊？？？到底问题出在何处呢

没有调试环境，没有上下文，...............................................

从你提供的东西没法分析，是那个页面，有哪些代码？

[symbol_bc]

呵呵，说的很明白了，这是一个运行时的错误，而且你肯定不是开发人员，基于安全原因，在远端把错误信息屏蔽了，所以你看不到具体是哪里出错了。
如果这个系统有日志的话，就看日志，没有日志的话，看你可不可以控制服务器，可以的话把
<customErrors mode="RemoteOnly" defaultRedirect="mycustompage.htm"/>这里改为
<customErrors mode="Off" defaultRedirect="mycustompage.htm"/>,就可以看到到底是哪里出的错，可是然后你怎么改啊。难道还要反编译源代码吗？这种时候最好联系写代码的人，要不然你不好搞啊

我也遇到过这样的问题，估计是哪个页面不符合服务器的要求。
如DLL文件引用，最常见的问题就是你没在.CS文件中引用DLL文件的命名空间

2楼果然是高手啊。。。我真不是开发人员，只是负责维护更新网站内容的
我看了下日志，连续有很多警告之后，就报错了。警告如下：

根据你在4楼的回复，这句
at SXFJ.DAL.main_News.SearchColumnID(String newsID) in d:/xxweb\App_Code\DAL\main_News.cs:line 1397
应该是在main_News.cs这个文件的1397行处错了，方法名是SearchColumnID，显然是要搜索列的id，而且写在DAL层，是一个访问数据库的错误，是这种错误经常出现的地方。
我的建议还是，如果你不是开发人员，不好搞。如果你的系统跑了好长时间了，最近才出错，那很可能你动了数据库的结构，造成的错误，建议你可以想想最近动了什么结构，改回去就好了。
否则如果系统是刚刚跑起来，那就联系开发人员吧，这属于bug了。

找到代码了。。。。
2楼的大哥能否再指点一二啊
/// <summary>
/// 根据新闻ID查询栏目ID
/// </summary>
/// <param name="newsID">新闻ID</param>
/// <returns></returns>
public static int SearchColumnID(string newsID)
{
string select_all_str = "select columnID from main_News where newsID=?newsID";
MySqlCommand com = new MySqlCommand();
com.CommandText = select_all_str;
com.Connection = my_con;
MySqlParameter p_newsID = new MySqlParameter();
p_newsID.ParameterName = "?newsID";
p_newsID.Value = newsID;
p_newsID.MySqlDbType = MySqlDbType.VarChar;
com.Parameters.Add(p_newsID);

int rowEffect = 0;
try
{
my_con.Open();
rowEffect = int.Parse(com.ExecuteScalar().ToString());
}
finally
{
my_con.Close();
}
return rowEffect;
}


其中my_con.Close();
是1397行
