把web.config中的<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
改成false又运行正常!
但过不知道多久又会出现这种情况,这是怎么回事呀?

[真相重于对错]

ArgumentException: Column 'url' does not belong to table preschoolList.]
列名不对

[casoon]

但是改下把web.config中的<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>把<compilation debug="true"/>改成false又可以运行正常呀!

url列不够长

[casoon]

url(nvarchar(100))内容不会超过100个字符!
如果不改web.config,而是刷新错误页面的话,又会提示别的错误信息:
Server Error in '/' Application.

DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'loginid'.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'loginid'.

Source Error:

The source code that generated this unhandled exception can only be shown when compiled in debug mode. To enable this, please follow one of the below steps, then request the URL:

1. Add a "Debug=true" directive at the top of the file that generated the error. Example:

<%@ Page Language="C#" Debug="true" %>

or:

2) Add the following section to the configuration file of your application:

<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>

Note that this second technique will cause all files within a given application to be compiled in debug mode. The first technique will cause only that particular file to be compiled in debug mode.

Important: Running applications in debug mode does incur a memory/performance overhead. You should make sure that an application has debugging disabled before deploying into production scenario.

感觉是数据库突然中断,所以页面上的有关显示数据的都出错了!
但为什么但是改下把web.config中的<configuration>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>改成false又可以了!

(1)重新上传一下你的 dll 文件
(2)检测你的 Web.config 里面数据库路径是否设置正确
