MFC获取文件操作

MFC文件操作大全

1.创建文件夹 CreateDirectory(%%1,NULL);
2.创建文件 CFile file;
file.Open(%%1,CFile::modeCreate|CFile::modeWrite);
3.删除文件 DeleteFile(%%1);
4.删除文件夹 RemoveDirectory(%%1);
5.删除一个目录下所有的文件夹 CFileFind finder; CString path; path.Format("%s\*.*",%%1); BOOL bWorking = finder.FindFile(path);
while (bWorking) {      bWorking = finder.FindNextFile();      if (finder.IsDirectory())      {          RemoveDirectory(finder.GetFilePath());      } }
6.清空文件夹 RemoveDirectory(%%1); CreateDirectory(%%1,NULL);
7.读取文件 char sRead[5120]; CFile mFile(_T(%%1),CFile::modeRead); while (sRead!=NULL) {      mFile.Read(sRead,5120);      CString %%2(sRead);      %%3 } mFile.Close();

8.写入文件 CFile mFile(_T(%%1), CFile::modeWrite|CFile::modeCreate); mFile.Write(%%2,sizeof(%%2)); mFile.Flush(); mFile.Close();

10.读取文件属性 DWORD dwAttrs = GetFileAttributes(%%1); if(dwAttrs & FILE_ATTRIBUTE_READONLY)      {            %%2 }      if(dwAttrs & FILE_ATTRIBUTE_NORMAL){            %%3 }

12.枚举一个目录下所有文件夹 CFileFind finder; CString path; path.Format("%s\*.*",%%1); BOOL bWorking = finder.FindFile(path);
while (bWorking) {      bWorking = finder.FindNextFile();      if(finder.IsDirectory()){          CString %%1=finder.GetFilePath();          %%2      } }

  //#include

  using std::string;

  char sep='/';

  #ifdef _WIN32

  sep='\';

  #endif

  CFileFind finder;

  CString path;

  path.Format("%s\*.*",%%1);

  BOOL bWorking = finder.FindFile(path);

  while (bWorking)

  {

       bWorking = finder.FindNextFile();

       if(!finder.IsDirectory() || finder.IsDots()){

           string s(finder.GetFileName());

           CString sourcefile(%%1);

           if(s.rfind(sep,s.length())!=string::npos)

           {

               sourcefile=sourcefile+"//"+s.substr(i+1,s.length()-i);

               CString targetfile(s.substr(i+1,s.length()-i));

               targetfile=%%2+"//"+targetfile/;

               CopyFile(sourcefile.GetBuffer(0),targetfile.GetBuffer(0),true);

           }

       }

  }

  20.提取扩展名

  CString path(%%1);

  CString %%2=path.Mid(path.ReverseFind('.'));

  21.提取文件名

  CString path(%%1);

  CString %%2=path.Mid(path.ReverseFind('\')+1);

  22.提取文件路径

  char appName[MAX_PATH];

  GetModualFileName(NULL,appName,MAX_PATH);

  //#include

  using std::string;

  string s(%%1);

  string newExt(%%2);

  string::size_type i=s.rfind('.',s.length());

  if(i!=string::npos)

  s.replace(i+1,newExt.length(),newExt);

  CString %%3(s);

   

  33.读取ini文件属性 CStdioFile inifile(%%1,CFile::modeRead); CString path = inifile.GetFilePath(); inifile.
