VS64位指定文件目录下的遍历

VS 32位上的文件遍历，在fileFolderPath下找fileExtension的文件。

vector<string> FindAllFile(const string fileFolderPath, const string fileExtension){struct _finddata_t fileInfo;    // 文件信息结构体  string fileFolder = fileFolderPath + "\\*." + fileExtension;vector<string> fileName;// 1. 第一次查找  long findResult = _findfirst(fileFolder.c_str(), &fileInfo);if (findResult == -1){_findclose(findResult);return fileName;}// 2. 循环查找  string temp1 = "\\";do{string temp;temp = fileFolderPath.c_str() + temp1 + fileInfo.name;//sprintf(fileName, "%s\\%s", fileFolderPath.c_str(), fileInfo.name);if (fileInfo.attrib == _A_ARCH)  // 是存档类型文件  {fileName.push_back(temp);}} while (!_findnext(findResult, &fileInfo));_findclose(findResult);return fileName;}

32位的资料很多，64位系统下的比较少，我用了这个在调用_findnext的时候容易报错。自己查了资料，写了个64位系统下的

#include <io.h>#include <AtlBase.h>std::string ws2s(const std::wstring& ws){std::string curLocale = setlocale(LC_ALL, NULL);        // curLocale = "C";setlocale(LC_ALL, "chs");const wchar_t* _Source = ws.c_str();size_t _Dsize = 2 * ws.size() + 1;char *_Dest = new char[_Dsize];memset(_Dest, 0, _Dsize);wcstombs(_Dest, _Source, _Dsize);std::string result = _Dest;delete[]_Dest;setlocale(LC_ALL, curLocale.c_str());return result;}std::wstring s2ws(const std::string& s){setlocale(LC_ALL, "chs");const char* _Source = s.c_str();size_t _Dsize = s.size() + 1;wchar_t *_Dest = new wchar_t[_Dsize];wmemset(_Dest, 0, _Dsize);mbstowcs(_Dest, _Source, _Dsize);std::wstring result = _Dest;delete[]_Dest;setlocale(LC_ALL, "C");return result;}vector<string> FindAllFile(const string path, const string fileExtension){wstring wpath = s2ws(path);LPCTSTR str = wpath.c_str();_tfinddata64_t c_file;intptr_t hFile;TCHAR root[MAX_PATH];_tcscpy(root, str);_tcscat(root, _T("\\*."));wstring wext = s2ws(fileExtension);LPCTSTR str2 = wext.c_str();_tcscat(root, str2);hFile = _tfindfirst64(root, &c_file);vector<string> filenames;if (hFile == -1)return filenames;do{TCHAR *fullPath = new TCHAR[MAX_PATH];_tcscpy(fullPath,str);_tcscat(fullPath, _T("\\"));_tcscat(fullPath, c_file.name);if (c_file.attrib == _A_ARCH){string file = ws2s(fullPath);filenames.push_back(file);}}while (_tfindnext64(hFile, &c_file) == 0);//close search handle_findclose(hFile);return filenames;}
