QString string;int m;m=string.toInt(); QString转unsigned char QString string;bool ok;unsigned char uch = string.toInt(&ok, 16); 二、String的转换 String转QString QString string;std::string str;string = QString::fromStdString(str); 三、QByteArray的转换 QByteArray转char * char *ch; ...

1、QString转换为QByteArray QString str ="123456";QByteArraybyte= str.toUtf8();//转换为Utf8格式byte.toLocal8Bit();//转换为本机编码格式 2、QByteArray转换为char * QByteArraybyte = "123456";char*c;c =byte.data(); 3、char *转换为QString ...
QByteArray，QByteArray转char*，QString转string...。Qt的第⼀篇⽂章，就先来总结⼀下我⽤过的数据之间的转换。1、QString转QByteArray QByteArray byte;QString string;byte = string.toLatin1();2、QByteArray转QString QByteArray byte;QString string;string = QString(byte);3、QString转String...
port=(unsignedshort)ui->LE_port->text().toShort();//获取端口号 1.QString转char * 先将QString转换为QByteArray,再将QByteArray转换为char *。 注意:不能用下面的转换形式char *mm = str.toLatin1().data();。因为这样的话,str.toLatin1()得到的QByteArray类型结果就不能保存,最后转换,mm的值就...
