@文心快码BaiduComateunsigned char数组转qstring 文心快码BaiduComate 要将unsigned char数组转换为QString,可以考虑以下几种方法: 方法一:通过QByteArray进行转换 这种方法利用了QByteArray和QString之间的转换功能,以及QByteArray对unsigned char数组的支持。 cpp #include <QByteArray> #include <QString>...
unsignedchar* str1 = (unsignedchar*)ba.data; 16进制QString和unsigned char数组互相转换 17位16进制mac字符串转为6位字节数组 demo: unsigned char* byteArr = hexStringToByteArray(QString("A1-B2-C3-D4-E5-F6")).data(); QVector<unsignedchar> hexStringToByteArray(constQString&strMac) { QVect...
//unsiged char *转QString unsigned char *str = "fdd" ; char *str1 = (char *)str; QString str2 = QString(QLatin1String(str1)); //QString 转化成char * QString str = "fdd"; QByteArray ba = str.toLatin1(); unsigned char * str1 = (unsigned char *)ba.data;...
//unsiged char *转QString unsigned char *str = "fdd" ; char *str1 = (char *)str; QString str2 = QString(QLatin1String(str1)); //QString 转化成char * QString str = "fdd"; QByteArray ba = str.toLatin1(); unsigned char * str1 = (unsigned char *)ba.data;分类: Qt 好...
unsigned char* 转qstring,unsignedchar*ch;std::stringstr=(char*)ch;QStringsstr=QString::fromStdString(str);
unsigned char* ch; QString str＝""； str=str.append(ch); 或者str+=ch; 你就这样用就可以了，没有问题的，要是真的还有问题就把ch先转成QChar
QByteArray byteArray;unsigned char * p = (unsigned char *)byteArray.data();
Qt下面，字符串都用QString，确实给开发者提供了方便，想想VC里面定义的各种变量类型，而且函数参数类型五花八门，经常需要今年新那个类型转换 Qt再使用第三方开源库时，由于库的类型基本上都是标准的类型，字符串遇的多的就是Char*类型 在Qt下...
extern static声明头.如果不加public ,函数默认为私有函数，调用就会出错。 [DllImport("CO ...
QString -> char: const QByteArray ba = string.toAscii(); // make ba const, because modifying this array might otherwise invalidate the pointer const char* sequence = ba.constData(); // now sequence will remain valid within the current scope. ...
