配置部分'system.web / profile'已经定义

标签： c# asp.net

我之前的web.config文件显然遇到了问题：HTML button sending input text data to ASP side。我实际上通过installing the System.Web.Providers package解决了这个问题。但是，当我再次运行我的代码时，我得到this screen。它说：Config section 'system.web/profile' already defined. Sections must only appear once per config file. See the help topic <location> for exceptions

这是我的web.config：

显然，问题在于第50行：<profile defaultProvider="DefaultProfileProvider">。然而，当我发表评论时，它会抱怨它之前的第一个标签。

我该如何解决这个问题？

1 个答案:

答案 0 :(得分：0)

您有两个<profile ...>和两个<sessionState ...>部分。

删除它们，看看它是怎么回事。

<profile defaultProvider="AspNetSqlProfileProvider">
     <providers>
           <clear />
           <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="LocalSqlServer" applicationName="/" />
     </providers>
</profile>

再向下

<sessionState mode="Custom" customProvider="DefaultSessionProvider">
     <providers>
          <add name="DefaultSessionProvider" type="System.Web.Providers.DefaultSessionStateProvider, System.Web.Providers, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="LocalSqlServer" />
     </providers>
</sessionState>
