所以昨天这段代码工作正常，今天我们去运行网站时遇到了这个配置错误。我已经查看了其他问题，虽然它们很有用，但我无法确定我在重复某个部分的位置。

这是我的错误： http://img.photobucket.com/albums/v506/Himaro/Programming/ConfigurationError.jpg enter image description here

和我的web.config中的代码：

先谢谢大家的帮助，我相信这是我失踪的小事。可能已经盯着代码太久了。

您有多个单独定义的成员资格提供程序：

<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，那么更新如下：

<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仅设置为defaultProvider。您可以使用默认情况下需要使用的提供程序更新此项。

Web中的多个成员标记。配置，然后就会出现这个错误。
