Qt 文件 字符转码

void ConvertCode(){QFile srcFile,dstFile;QTextStream in,out;QString fileName,dstFileName,tmpstr;srcFile.setFileName("Version.xml");srcFile.open(QFile::ReadWrite);in.setDevice(&srcFile);in.setAutoDetectUnicode(false);in.setCodec(srcCodec);tmpstr = in.readAll();dstFile.setFileName("VersionU.xml");dstFile.open(QFile::ReadWrite |QFile::Truncate);out.setDevice(&dstFile);out.setCodec(desCodec);out<<tmpstr;srcFile.close();dstFile.close();}

经常用到的！
