(1)
//目錄是否存在的檢查:
bool CheckFolderExist(const string &strPath)
{
WIN32_FIND_DATA wfd;
bool rValue = false;
HANDLE hFind = FindFirstFile(strPath.c_str(), &wfd);
if ((hFind != INVALID_HANDLE_VALUE) && (wfd.dwFileAttributes & FILE_ATTRIBUTE_DIRECTORY))
{
rValue = true;
}
FindClose(hFind);
return rValue;
}
(2)PathFileExists("yourfile") 但是使用時候需要 #include "Shlwapi.h"
(3)
bool FileExists(LPCTSTR lpszFileName, bool bIsDirCheck)
{
DWORD dwAttributes = GetFileAttributes(lpszFileName);
if(dwAttributes == 0xFFFFFFFF)
{
return false;
}
if((dwAttributes & FILE_ATTRIBUTE_DIRECTORY) == FILE_ATTRIBUTE_DIRECTORY)
{
return bIsDirCheck;
}
else
{
return !bIsDirCheck;
}
}
(4)使用boost的filesystem類庫的exists函數
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/path.hpp>
#include <boost/filesystem/convenience.hpp>
int GetFilePath(std::string &strFilePath)
{
string strPath;
int nRes = 0;
//指定路徑
strPath = "D:/myTest/Test1/Test2";
namespace fs = boost::filesystem;
//路徑的可移植
fs::path full_path( fs::initial_path() );
full_path = fs::system_complete( fs::path(strPath, fs::native ) );
//判斷各級子目錄是否存在,不存在則需要建立
if ( !fs::exists( full_path ) )
{
// 建立多層子目錄
bool bRet = fs::create_directories(full_path);
if (false == bRet)
{
return -1;
}
}
strFilePath = full_path.native_directory_string();
return 0;
}
