convert unsigned char* to String
提问by Cyril
I am little poor in type casting. I have a string in xmlChar*(which is unsigned char*), I want to convert this unsigned char to a std::stringtype.
我在类型转换方面有点差。我有一个字符串xmlChar*（它是无符号字符*），我想将此无符号字符转换为std::string类型。
xmlChar* name = "Some data";
I tried my best to type cast , but I couldn't a way to convert it.
我尽力输入 cast ，但我无法转换它。
回答by sasha.sochka
std::string sName(reinterpret_cast<char*>(name));
reinterpret_cast<char*>(name)casts from unsigned char*to char*in an unsafe way but that's the one which should be used here. Then you call the ordinary constructor of std::string.
reinterpret_cast<char*>(name)unsigned char*以char*一种不安全的方式从to转换，但这是应该在这里使用的方式。然后调用 的普通构造函数std::string。
You could also do it C-style (not recommended):
你也可以做 C 风格的（不推荐）：
std::string sName((char*) name);
