我有一个程序可以成功搜索特定驱动器中特定扩展名的文件(我正在使用 Windows),让我们说它是“C:\”,然后在控制台上打印这些文件。现在我想概括我的程序。我希望我的程序将在所有分区(驱动器)中搜索..我该怎么做..我应该使用哪个函数..这是我的代码示例
int SearchDirectory(std::vector<std::string> &refvecFiles,
const std::string &refcstrRootDirectory,
const std::string &refcstrExtension,
bool bSearchSubdirectories = true)
{
std::string strFilePath; // Filepath
std::string strPattern; // Pattern
std::string strExtension; // Extension
HANDLE hFile; // Handle to file
WIN32_FIND_DATA FileInformation; // File information
strPattern = refcstrRootDirectory + "\\*.*";
hFile = ::FindFirstFile(strPattern.c_str(), &FileInformation);
if(hFile != INVALID_HANDLE_VALUE)
{
do
{
if(FileInformation.cFileName[0] != '.')
{
strFilePath.erase();
strFilePath = refcstrRootDirectory + "\\" + FileInformation.cFileName;
if(FileInformation.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY)
{
if(bSearchSubdirectories)
{
// Search subdirectory
int iRC = SearchDirectory(refvecFiles,
strFilePath,
refcstrExtension,
bSearchSubdirectories);
if(iRC)
return iRC;
}
}
else
{
// Check extension
strExtension = FileInformation.cFileName;
strExtension = strExtension.substr(strExtension.rfind(".") + 1);
if(strExtension == refcstrExtension)
{
// Save filename
refvecFiles.push_back(strFilePath);
}
}
}
} while(::FindNextFile(hFile, &FileInformation) == TRUE);
// Close handle
::FindClose(hFile);
DWORD dwError = ::GetLastError();
if(dwError != ERROR_NO_MORE_FILES)
return dwError;
}
return 0;
}
int main()
{
int iRC = 0;
std::vector<std::string> vecAviFiles;
std::vector<std::string> vecTxtFiles;
// Search 'c:' for '.avi' files including subdirectories
iRC = SearchDirectory(vecAviFiles, "c:", "apk");
if(iRC)
{
std::cout << "Error " << iRC << std::endl;
return -1;
}
// Print results
for(std::vector<std::string>::iterator iterAvi = vecAviFiles.begin();
iterAvi != vecAviFiles.end();
++iterAvi)
std::cout << *iterAvi << std::endl;
// Search 'c:\textfiles' for '.txt' files excluding subdirectories
iRC = SearchDirectory(vecTxtFiles, "c:", "txt", false);
if(iRC)
{
std::cout << "Error " << iRC << std::endl;
return -1;
}
// Print results
for(std::vector<std::string>::iterator iterTxt = vecTxtFiles.begin();
iterTxt != vecTxtFiles.end();
++iterTxt)
std::cout << *iterTxt << std::endl;
// Wait for keystroke
_getch();
return 0;
}
