Question

我在使用Enterprise Library 5.0登录sql server 2008 Express时遇到问题它适用于我的开发环境（VS2010），但不适用于我的Server 2008 / SQL Server 2008 Express。

为确保它不是数据库，我还使用平面文件进行了测试。也没用。

这两个文件都存在于我的bin目录中。

Microsoft.Practices.EnterpriseLibrary.Logging.dll Microsoft.Practices.EnterpriseLibrary.Logging.Database.dll

我的web.config看起来像这样：

<configSections>
<section name="loggingConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Logging.Configuration.LoggingSettings, Microsoft.Practices.EnterpriseLibrary.Logging, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="true" />

我使用此用户手动连接（作为测试），我可以使用此用户在日志表中输入数据。

我收到此错误：例外：

您收到的错误表明Entlib尚未正确初始化。数据库是一个红色的鲱鱼 - 你现在还没有完成日志工作。

＆lt; configSections＆gt;中是否定义了日志记录部分？你的web.config文件的元素？

更新

您添加了configSections元素，但您发布的内容格式不正确：＆lt; configSections＆gt;＆lt; / sectionGroup＆gt;。如果这是准确的，那就是问题，配置错误。修复关闭标记，它应该开始工作。
