每个配置文件中的节只能出现一次 [英] Sections must only appear once per config file

问题描述

因此，昨天该代码工作正常，而今天，当我们去运行站点时，遇到此配置错误。我浏览了所问的其他问题，尽管它们很有帮助，但我无法查明我在哪里重复一节。

so yesterday this code was working just fine and today as we went to run the site we are getting this configuration error. I have looked through the other questions asked and although they were helpful I have not been able to pinpoint where I am repeating a section.

这是我的错误：

和我的web.config中的代码：

and the code in my web.config:

在此先感谢大家的帮助，我确定这是我所缺少的东西。盯着代码太久了。

Thank you all in advance for the help, I'm sure it's something small I'm missing. Been staring at the code for too long maybe.

推荐答案

您有多个分别定义的成员资格提供程序：

You have multiple membership providers defined separately:

<membership defaultProvider="DefaultProvider">
  <providers>
    <add name="DefaultProvider" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
  </providers>
</membership>
...
<membership defaultProvider="DefaultMembershipProvider">
  <providers>
    <add name="DefaultMembershipProvider" type="System.Web.Providers.DefaultMembershipProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
  </providers>
</membership>

删除其中一个应该摆脱该错误。但是，如果您需要两个提供商都进行以下更新：

Removing one of them should get rid of that error. But if you need to have both providers then update as follows:

<membership defaultProvider="MembershipProvider2">
  <providers>
    <add name="MembershipProvider1" type="WebMatrix.WebData.SimpleMembershipProvider, WebMatrix.WebData" />
    <add name="MembershipProvider2" type="System.Web.Providers.DefaultMembershipProvider, System.Web.Providers, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" connectionStringName="DefaultConnection" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/" />
  </providers>
</membership>

此处 MembershipProvider2 设置为<$ c例如，$ c> defaultProvider 。您将使用需要用作默认值的提供程序来更新它。

Here MembershipProvider2 is set as defaultProvider just for example. You would update this with whichever providers you need to use as default.
