三种向文件写入CString数据的方法

// use C to write into file FILE *pFile=fopen("1.txt","w"); CString strTemp = "hello world!"; fwrite(strTemp,1,strTemp.GetLength(),pFile); fflush(pFile); fclose(pFile); // use C++ to write into file ofstream ofs("2.txt"); CString str = "Use C++.Hello World !"; ofs.write(str,str.GetLength()); ofs.flush(); ofs.close(); // use MFC to write into file CString str = "Use CFile,Hello World !"; CFile file("3.txt",CFile::modeCreate | CFile::modeWrite); file.Write(str,str.GetLength()); file.Flush(); file.Close();
