1 获取文件夹中所有文件名，包含子文件夹中的文件名

void getFiles(string path, vector <string> & files)
{long hFile = 0;struct _finddata_t fileinfo;string pathp;if ((hFile = _findfirst(pathp.assign(path).append("\\*").c_str(), &fileinfo)) != -1){do{if ((fileinfo.attrib &  _A_SUBDIR)){if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0){					getFiles(pathp.assign(path).append("/").append(fileinfo.name), files);}}else{string filestr = fileinfo.name;files.push_back(filestr);}} while (_findnext(hFile, &fileinfo) == 0);_findclose(hFile);}
}

2 获取文件夹中所有文件路径，包含子文件夹中的文件路径

void getFiles(string path, vector <string> & files)
{long hFile = 0;struct _finddata_t fileinfo;string pathp;if ((hFile = _findfirst(pathp.assign(path).append("\\*").c_str(), &fileinfo)) != -1){do{if ((fileinfo.attrib &  _A_SUBDIR)){if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0){					getFiles(pathp.assign(path).append("//").append(fileinfo.name), files);}}else{string filestr = fileinfo.name;files.push_back(pathp.assign(path).append("//").append(filestr));}} while (_findnext(hFile, &fileinfo) == 0);_findclose(hFile);}
}

3 获取母文件夹中所有文件名，不包含子文件夹中的文件名

void getFiles(string path, vector <string> & files)
{long hFile = 0;struct _finddata_t fileinfo;string pathp;if ((hFile = _findfirst(pathp.assign(path).append("\\*").c_str(), &fileinfo)) != -1){do{if ((fileinfo.attrib &  _A_SUBDIR)){if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0){					continue;}}else{string filestr = fileinfo.name;files.push_back(filestr);}} while (_findnext(hFile, &fileinfo) == 0);_findclose(hFile);}
}

4 只获取母文件夹中的文件路径，不包含子文件夹中的文件

void getFiles(string path, vector <string> & files)
{long hFile = 0;struct _finddata_t fileinfo;string pathp;if ((hFile = _findfirst(pathp.assign(path).append("\\*").c_str(), &fileinfo)) != -1){do{if ((fileinfo.attrib &  _A_SUBDIR)){if (strcmp(fileinfo.name, ".") != 0 && strcmp(fileinfo.name, "..") != 0){					continue;}}else{string filestr = fileinfo.name;files.push_back(pathp.assign(path).append("//").append(filestr));}} while (_findnext(hFile, &fileinfo) == 0);_findclose(hFile);}
}

5 主函数以及文件夹情况

int main()
{string basedir = "data";vector <string> files;getFiles(basedir, files);int filenum = files.size();for (int i = 0; i < filenum; i++){cout << files[i] << endl;}system("pause");return 0;
}
