复制代码代码如下: #include Windows.h #include tchar.h #include list #include set #include cassert #include string typedef std::basic_stringTCHAR _tstring; //宽字符串 typedef std::list_tst

复制代码代码如下:

#include <Windows.h>
#include <tchar.h>
#include <list>
#include <set>
#include <cassert>
#include <string>
typedef std::basic_string<TCHAR> _tstring; //宽字符串
typedef std::list<_tstring> _tslist; //字符串链表
/*

返回文件名的链表。

filepath 目录的完整路径，不带//

filefilterlist 文件扩展名列表，可以是多种类型的组合，比如说.txt;.xls;.doc

isordered 是否对文件名排序

_tslist SearchFile(LPCTSTR filepath, LPCTSTR filefilterlist = _T(".*" ), bool isordered = true)

{

assert(filepath != NULL);

TCHAR buffer[MAX_PATH];

#if _MSC_VER > 1310

/* 1310 for Microsoft Visual C++ .NET 2003. 1310 represents /version 13 and a 1.0 point release. The Visual C++ 2005 compiler version is 1400, the number.

_tcscpy_s(buffer, filepath); //_tcscpy_s is a micro for strcpy_s and strwcpy_s

#else

_tcscpy(buffer,filepath); //

#endif

_tslist filenamelist; // initial length is 100

WIN32_FIND_DATA finddata;

HANDLE searchhandle = INVALID_HANDLE_VALUE;

size_t length= _tcslen(filepath);

if (buffer[length-1] != _T('//'))
{

        _tcscat_s(buffer,_T("//*")); // 向字符串结尾添加/*, 用来查找所有文件
    }
    if ( (searchhandle = ::FindFirstFile(buffer, &finddata)) != INVALID_HANDLE_VALUE )
    {

while (::FindNextFile(searchhandle, &finddata) != 0)
{

        if ( !(finddata.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY) )   // 为文件
       {
          if ( !_tcsicmp(filefilterlist, _T(".*")))   // 将所有文件输出到链表

             filenamelist.push_back(finddata.cFileName);
          else
         {
            //get file filter list string, a example, file filter may be ".txt;.xls;.doc"
            _tstring filterstring = filefilterlist;
            _tstring filename(finddata.cFileName);
            _tstring::size_type index = filename.find_last_of(_T('.'));
            if (index == _tstring::npos) // 文件没有扩展名，跳过
               continue;
            else
           {
                 _tstring extname = filename.substr(index+1); //取得文件的扩展名
                _tstring::size_type exist;
                exist = filterstring.find(extname);
                if (exist != _tstring::npos) //判断文件的扩展名是否在扩展名列表里
                 filenamelist.push_back(finddata.cFileName);
              }
            }
         }
      }
    }
    ::FindClose( searchhandle );
