Question

您选择的数据存储存在问题。这可能是由无效的服务器名称或凭据或权限不足引起的。它也可能是由未启用角色管理器功能引起的。单击下面的按钮可重定向到可以选择新数据存储的页面。

以下消息可能有助于诊断问题：每个配置文件只能出现一次。有关例外，请参阅帮助主题。（C：\ Users \ berkay.bektas \ Desktop \ x \ Yalcomania_Project \ Yalcomania_APP \ YalcomaniaTours \ YalcomaniaTours.UI.WebApp \ web.config第20行）

猜测它必须到达：

<roleManager enabled="true" />

和

<roleManager>
  <providers>
    <clear/>
    <add name="AspNetSqlRoleProvider" connectionStringName="MembershipConn" applicationName="/" type="System.Web.Security.SqlRoleProvider, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
    <add name="AspNetWindowsTokenRoleProvider" applicationName="/" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
  </providers>
</roleManager>

请注意错误消息“章节必须只显示一次...”您有两个roleManager部分。尝试将其组合起来：

<roleManager enabled="true">
  <providers>
    <clear/>
    <add name="AspNetSqlRoleProvider" connectionStringName="MembershipConn" applicationName="/" type="System.Web.Security.SqlRoleProvider, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
    <add name="AspNetWindowsTokenRoleProvider" applicationName="/" type="System.Web.Security.WindowsTokenRoleProvider, System.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"/>
  </providers>
</roleManager>

此外，我想你想在你的roleManager部分提供defaultProvider。

每个配置文件只能出现一次。有关例外，请参阅帮助主题
