递归文件搜索使用C ++ MFC？ [英] Recursive file search using C++ MFC?

问题描述

使用C ++和MFC递归搜索文件的最简洁的方法是什么？

What is the cleanest way to recursively search for files using C++ and MFC?

编辑：任何这些解决方案都能够通过一遍使用多个过滤器？我想用CFileFind我可以过滤*。*然后写自定义代码进一步过滤到不同的文件类型。是否有提供内置的多个过滤器（即* .exe，*。dll）？

Do any of these solutions offer the ability to use multiple filters through one pass? I guess with CFileFind I could filter on *.* and then write custom code to further filter into different file types. Does anything offer built-in multiple filters (ie. *.exe,*.dll)?

EDIT2：刚刚实现了一个明显的假设， EDIT无效。如果我想用CFileFind进行递归搜索，我必须使用*。*作为我的通配符，因为否则子目录将不会匹配，并且不会发生递归。因此，不同文件范围的过滤都必须单独处理。

Just realized an obvious assumption that I was making that makes my previous EDIT invalid. If I am trying to do a recursive search with CFileFind, I have to use *.* as my wildcard because otherwise subdirectories won't be matched and no recursion will take place. So filtering on different file-extentions will have to be handled separately regardless.

推荐答案

使用 CFileFind 。

请查看此示例从MSDN：

void Recurse(LPCTSTR pstr)
{
   CFileFind finder;

   // build a string with wildcards
   CString strWildcard(pstr);
   strWildcard += _T("\\*.*");

   // start working for files
   BOOL bWorking = finder.FindFile(strWildcard);

   while (bWorking)
   {
      bWorking = finder.FindNextFile();

      // skip . and .. files; otherwise, we'd
      // recur infinitely!

      if (finder.IsDots())
         continue;

      // if it's a directory, recursively search it

      if (finder.IsDirectory())
      {
         CString str = finder.GetFilePath();
         cout << (LPCTSTR) str << endl;
         Recurse(str);
      }
   }

   finder.Close();
}
