Question

使用Enterprise Library在多个文件之间共享配置信息时遇到了一些问题。我有三个配置文件（app.config，dataConfiguration.config和exceptionHandlingConfiguration.config）。我正在使用.NET 4.0框架中的Windows 7计算机上的Enterprise Library 5.0和Visual Studio 2012。

在App.config中，我有以下

<configuration>
  <configSections>
    <section name="enterpriseLibrary.ConfigurationSource" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.ConfigurationSourceSection, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" requirePermission="false" />
    <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    <section name="exceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"/>

    </sectionGroup>

  </configSections>
    <appSettings> 
    </appSettings>
    <enterpriseLibrary.ConfigurationSource selectedSource="SysConfig">
        <sources>
            <add name="SysConfig" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.SystemConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                 />
            <add name="DataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                filePath="dataConfiguration.config" />
            <add name="ExceptionHandling" type="Microsoft.Practices.EnterpriseLibrary.Common.Configuration.FileConfigurationSource, Microsoft.Practices.EnterpriseLibrary.Common, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
                filePath="exceptionHandlingConfiguration.config" />
        </sources>
        <redirectSections>
            <add sourceName="DataConfiguration" name="dataConfiguration" />
            <add sourceName="ExceptionHandling" name="exceptionHandling" />
        </redirectSections>
    </enterpriseLibrary.ConfigurationSource>
</configuration>

exceptionHandlingConfiguration.config包含

<?xml version="1.0" encoding="utf-8"?> 
<configuration>
  <exceptionHandling>
    <exceptionPolicies>
      <add name="Policy">
        <exceptionTypes>
          <add name="All Exceptions" type="System.Exception, mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089"
              postHandlingAction="NotifyRethrow" />
        </exceptionTypes>
      </add>
    </exceptionPolicies>
  </exceptionHandling>
  <validation />
  <policyInjection>
    <policies>
      <add name="Application Policy">
        <handlers>
           <add type="Microsoft.Practices.EnterpriseLibrary.Validation.PolicyInjection.ValidationCallHandler, Microsoft.Practices.EnterpriseLibrary.Validation, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              specificationSource="Both" name="Validation Call Handler" /> 

        </handlers>
      </add>
      <add name="Global Policy">
        <handlers>
          <add type="Microsoft.Practices.EnterpriseLibrary.ExceptionHandling.PolicyInjection.ExceptionCallHandler, Microsoft.Practices.EnterpriseLibrary.ExceptionHandling, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35"
              exceptionPolicyName="Policy" name="Exception Handling Call Handler" /> 

        </handlers>
      </add>
    </policies>
  </policyInjection>
</configuration>

虽然dataConfiguration.config包含

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <configSections>
      <section name="dataConfiguration" type="Microsoft.Practices.EnterpriseLibrary.Data.Configuration.DatabaseSettings, Microsoft.Practices.EnterpriseLibrary.Data, Version=5.0.414.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />
    </configSections>
  <dataConfiguration defaultDatabase="JDBDatabase" />
    <connectionStrings>
        <add name="JDBDatabase" connectionString="TestBookDB; server=Mononobe1423; Integrated Security=true;"
            providerName="System.Data.SqlClient" /> 
    </connectionStrings>
</configuration>

我遇到的问题是当我运行代码时，收到错误消息

配置文件dataConfiguration.config没有root标签

如上所示，所有三个文件都包含配置标记。所以我迷失了错误是什么以及为什么我无法使用

中的任何一个访问其他文件中定义的部分对象

var execonfig = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);
var db = execonfig.ConnectionStrings.ConnectionStrings["JDBDatabase"];

或

IConfigurationSource configSource = ConfigurationSourceFactory.Create();
var db =  configSource.GetSection(DatabaseSettings.SectionName);

任何人都知道我错了什么？

配置文件dataConfiguration.config没有root <配置>标记</configuration>
