c++中 打开一个文件夹下的所有特定格式的文件（如JPG）

//getFiles(filePath, "JPG", imageFilePathNames2);

//filePath   是 "F:\新建文件夹"  这样的

void getFiles(string path, string exd, vector<string> &files){//文件句柄long   hFile = 0;//文件信息struct _finddata_t fileinfo;string pathName, exdName;if (0 != strcmp(exd.c_str(), "")){exdName = "\\*." + exd;}else{exdName = "\\*";}if ((hFile = _findfirst(pathName.assign(path).append(exdName).c_str(), &fileinfo)) != -1){do{{if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0)files.push_back(pathName.assign(path).append("\\").append(fileinfo.name));}} while (_findnext(hFile, &fileinfo) == 0);_findclose(hFile);}}
