三种向文件写入CString数据的方法

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