ASP.NET應用程序只部分讀取外部配置

Question

我有一個ASP.NET Web應用程序，並試圖引用外部配置（使用企業應用程序塊配置）的一些配置，但它不完全正常工作。

我以前擁有web.config中的所有配置信息（它正在工作），但我們希望在多個應用程序之間共享這些配置信息。當我將configurationSource標籤放入web.config中，並通過WebConfigurationManager對象讀取配置時，它會加載一些外部配置信息（日誌記錄），但不會加載connectionStrings，也不會加載我創建的自定義部分。所以它正在閱讀（日誌記錄工作），但有些點沒有連接，我的連接字符串沒有通過。

再一次，它在web.config中全部運行。我正在運行.NET 3.5。

任何想法是什麼需要改變，以便能夠引用一個外部配置源，並讓它都通過？

Answer 1

是良好形成的XML配置？前幾天我遇到了一個Wcf配置部分的問題，我沒有正確關閉標籤，但除了服務沒有響應之外，沒有明顯的錯誤。

您是否考慮過使用System.Configuration.SectionInformation.ConfigSource屬性的本機外化行爲？它的用法如下：

<pages configSource="pages.config"/> 

更多信息，請參見SectionInformation.ConfigSource topic。

應該注意的是，由於安全考慮，它只支持相對路徑名。哦，它只能應用於ConfigurationSection，而不是ConfigurationElement。
