cstring string CString QString char*之间的联系与区别 cstring 和string.h头文件等价,cstring是c++版本的头文件,string.h是c版本的头文件,可以理解为同一个东西,面向char*string 头文件定义了 c++标准库 中的一个类,包含各种字符串的操作,CString 是MFC定义的一个类...
In order to convert a QString to a char*, then you first need to get a latin1 representation of the string by calling toLatin1() on it which will return a QByteArray. Then call data() on the QByteArray to get a pointer to the data stored in the byte array. See the documentation...
#else typedefcharTCHAR; #endif 所以在工程中应该可以关闭对于Unicode的支持，从而可以直接转换。这个做法是右击工程名—〉Property—〉General中的characterset中选择notset，这样，本文开头的那段代码就可以正确的执行了。 QStringGB_To_Utf8(char*strText) { returnQString::fromLocal8Bit(strText); }

toStdString(); 将标准C++字符串转换为CString: 接下来,使用CString的构造函数或赋值操作将std::string转换为CString。注意,这里可能需要处理字符编码的转换,特别是如果你的QString包含非ASCII字符。 cpp CString cstr(stdStr.c_str()); // 使用std::string的c_str()方法获取C风格字符串 或者,如果你使用的...

To convert a char* to a QString you can use the QString constructor that takes a QLatin1String, e.g: QString string = QString(QLatin1String(c_str2)) ; 还有其他多种方法: 方法一 --- #define G2U(s) ( QTextCodec::codecForName("GBK")->...
