C# ASP.NET中的Web配置出错

ASP.NET WebForms和我正在对用户进行身份验证，但我在web.config文件中遇到此错误：

<?xml version="1.0"?>

谢谢大家

您的位置部分应该在

标记外指定，在

部分内指定，您需要添加

标记。请参考下面修改的配置文件

<?xml version="1.0"?>

<configuration>
  <configSections>
    <section name="entityFramework" type="System.Data.Entity.Internal.ConfigFile.EntityFrameworkSection, EntityFramework, Version=5.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false"/>
    <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
      <section name="webapp1.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
    </sectionGroup>
  </configSections>
  <connectionStrings>
    <add name="constr" providerName="System.Data.SqlClient" connectionString="Data Source=localhost;Initial Catalog=Gy;Integrated Security=SSPI;"/>
  </connectionStrings>

在关闭配置标记之前放置位置标记，如下所示

<location path="Admin">
<system.web>
  <authorization>
    <allow roles="admin"/>
    <deny users="*"/>
  </authorization>
</system.web>

希望这对…有帮助
