IAppHostAdminManager：：ConfigManager 属性

获取 一个 IAppHostConfigManager 接口，该接口提供对 IIS 7 配置系统中的物理文件的访问权限。

语法

HRESULT get_ConfigManager(  
   [out,  
   retval] IAppHostConfigManager** ppConfigManager  
);  

parameters

ppConfigManager
指向接口的指针的 IAppHostConfigManager 指针。

返回值

HRESULT。 可能的值包括（但并不限于）下表中的项。
