“/”应用程序中的服务器错误。

Unknown database 'zhaomingr'

说明: 执行当前 Web 请求期间,出现未经处理的异常。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: MySql.Data.MySqlClient.MySqlException: Unknown database 'zhaomingr'

源错误:

只有在调试模式下进行编译时,生成此未经处理的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。
