四、将unsigned char数组转为QString表示的16进制 unsigned char数组转为QString unsignedcharun_char[]{0xff,0xee,0xdd,0xcc,0xaa}; QString ucTos = QString(QByteArray((char*)un_char,5).toHex());
QHostAddress address(string); 11、QString转unsigned char QString string; bool ok; unsigned char uch = string.toInt(&ok, 16); 12、unsigned char转QString unsigned char uch; QString string = QString::number(uch,16); 13、int转QString int m; QString string; string=QString::number(m); ...

在Qt中,将unsigned char数组转换为QString通常涉及将字节数据视为某种编码的字符串。最常见的是将字节数据视为UTF-8编码的字符串,因为QString内部使用Unicode编码,但它能够很好地处理UTF-8编码的字符串。 以下是一个分步骤的解决方案,包括代码示例: 1. 理解unsigned char数组和QString的数据结构 unsigned char数组是...
unsigned char *ret = (unsigned char *)ch; 1 2 6. const unsigned char * 转 QString const unsigned char str[5] = {'t', 'e', 's', 't'}; string s = (char *)str; qDebug() << QString::fromStdString(s); 1 2 3
