本文介绍了一种在Windows环境下批量展示文件属性的方法，通过解析分隔的文件路径，使用SHELLEXECUTEINFO结构和ShellExecuteEx函数实现单个文件属性展示；对于多个文件，则利用IShellFolder和IDataObject接口，结合SHGetSpecialFolderLocation和SHGetDesktopFolder函数获取文件的ITEMIDLIST，最终通过SHMultiFileProperties函数展示多个文件的属性。

代码如下：

1 // csFilePath 文件路径，以|分隔。 nPathes 路径数。
2 void CGetDirectoryDlg::ShowPropertiesByPath(CString csFilePath, int nPathes)
3 {
4      if(csFilePath.IsEmpty())
5     {
6          return;
7     }
8      // 单个文件属性
9      if(nPathes == 1)
10     {
11         SHELLEXECUTEINFO sei;
12         ZeroMemory(&sei, sizeof(sei));
13         sei.cbSize = sizeof(SHELLEXECUTEINFO);
14         sei.hwnd = m_hWnd;
15         sei.lpParameters = NULL;
16         sei.nShow = 0;
17         sei.lpIDList =  NULL;
18         sei.hInstApp = 0;
19         sei.lpFile = csFilePath; // 要显示属性的文件
20         sei.lpVerb = L " properties ";
21         sei.fMask = SEE_MASK_IDLIST | SEE_MASK_NOCLOSEPROCESS | SEE_MASK_INVOKEIDLIST |
22
23 SEE_MASK_FLAG_NO_UI;
24         ShellExecuteEx(&sei);
25          return;
26     }
