获取或设置应在其中提交更改的配置路径。

语法

HRESULT get_CommitPath(  
   [out,  
   retval,  
   string] BSTR* pbstrCommitPath  
);  
HRESULT put_CommitPath(  
   BSTR bstrCommitPath  
);  

parameters

pbstrCommitPath
指向 的 BSTR 指针，其中包含应在其中提交更改的配置路径。

bstrCommitPath
一个 BSTR 包含新提交路径的 。

返回值

HRESULT。 可能的值包括（但并不限于）下表中的项。

示例

下面的代码示例演示如何设置 CommitPath 属性、更改 IIS 7 配置，然后使用 IAppHostWritableAdminManager：：CommitChanges 方法将这些更改提交到 IIS 7 配置系统。
