那位可以帮忙？

你没有初始化啊。。。

你连接数据库的语句贴出来看看啊

好的！

又出现这个问题了！！！！



“/”应用程序中的服务器错误。

用户 'sa' 登录失败。
说明: 执行当前 Web 请求期间，出现未处理的异常。请检查堆栈跟踪信息，以了解有关该错误以及代码中导致错误的出处的详细信息。

异常详细信息: System.Data.SqlClient.SqlException: 用户 'sa' 登录失败。

源错误:

只有在调试模式下进行编译时，生成此未处理异常的源代码才会显示出来。若要启用此功能，请执行以下步骤之一，然后请求 URL:

1. 在产生错误的文件的顶部添加一条“Debug=true”指令。例如:

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

或:

2. 将以下的节添加到应用程序的配置文件中:

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

请注意，第二个步骤将使给定应用程序中的所有文件在调试模式下进行编译；第一个步骤仅使该特定文件在调试模式下进行编译。

重要事项: 以调试模式运行应用程序一定会产生内存/性能系统开销。在部署到生产方案之前，应确保应用程序调试已禁用。

这个是文奇小说系统！！！

有点不明白，没看过这个系统，按使用ConnectionString情况下，一般上就有ms推出的xxxDataSource这个控件来的，在其web.config中会出现类如
<connectionStrings>
        <add name="NorthwindConnectionString" connectionString="Data Source=localhost;Initial Catalog=Northwind;Integrated Security=True"
            providerName="System.Data.SqlClient" />
    </connectionStrings>
这样的xml，而使用ConfigurationSettings.AppSettings["xxx"]这种方式会在web.config下存在类如<appSettings>...</appSettings>中使用add key，value的形式保存连接字符串，你查查代码看
在web下进行跟c/s下还是小有区别，就是连接的字符串跟配置上有些许出入，详细的其实可以参考msdn

是因为你的数据库sa密码和配置文件的sa密码不一致。。。所以就出现sa登录失败。。。

是不是没有包括数据库的命名空间:
比如：using System.Data.SqlClient;
