Question

我有一个ASP.NET Web应用程序，并尝试为某些配置引用外部配置（使用企业应用程序块配置），但它并没有完全正常工作。

我以前拥有web.config中的所有配置信息（并且它正在运行），但我们希望在多个应用程序之间共享一些配置信息。当我将configurationSource标记放在web.config中，并通过WebConfigurationManager对象读取配置时，它会加载一些外部配置信息（Logging），但不会加载connectionStrings而不是我创建的自定义部分。所以它正在读取它（日志记录正在工作），但有些点没有被连接，我的连接字符串也没有通过。

同样，它在web.config中完全有效。我正在运行.NET 3.5。

知道需要更改什么才能引用外部配置源并让它们全部通过？

Configuration webConfig =
    System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
ConnectionStringSettingsCollection connectionStrings =
    System.Web.Configuration.WebConfigurationManager.ConnectionStrings;

配置Xml是否形成良好？前几天我遇到了Wcf配置部分的问题，我没有正确关闭标签，但除了没有响应的服务之外没有明显的错误。

您是否考虑过使用System.Configuration.SectionInformation.ConfigSource属性的原生外化行为？它的用法如下：

<pages configSource="pages.config"/>

有关详细信息，请参阅SectionInformation.ConfigSource topic。

应该注意，由于安全问题，它仅支持相对路径名。哦，它只能应用于ConfigurationSection，而不是ConfigurationElement。

ASP.NET应用程序仅部分读取外部配置
