语法

HRESULT GetAdminSection(  
   [in,  
   string] BSTR bstrSectionName,  
   [in,  
   string] BSTR bstrPath,  
   [out,  
   retval] IAppHostElement** ppAdminSection  
);  

parameters

bstrSectionName
一个 ， BSTR 其中包含配置系统中有效节名称的路径。

bstrPath
包含 BSTR 配置系统路径的 。

ppAdminSection
指向 IAppHostElement 接口的指针的指针。

返回值

HRESULT。 可能的值包括（但并不限于）下表中的项。

备注

对于指定的配置路径，此方法的返回值表示分层合并配置集中的相应值。 若要设置配置路径，请使用 bstrPath 此方法的 参数。

示例

下面的代码示例使用 IAppHostAdminManager 接口获取 MACHINE/WEBROOT/APPHOST 配置路径中 system.webServer/asp 配置节的所有合并子元素。
