将unsigned char *转换为String [英] convert unsigned char* to String

问题描述

我在铸造类型上有点差。我在 xmlChar * （这是unsigned char *）中有一个字符串，我想将这个unsigned char转换为 std :: string type。

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::string type.

xmlChar* name = "Some data";

我尽力键入cast，但我不能转换它。 p>

I tried my best to type cast , but I couldn't a way to convert it.

推荐答案

std::string sName(reinterpret_cast<char*>(name));

reinterpret_cast< char *>（name）以不安全的方式从 unsigned char * 转换为 char *，但这是应该在这里使用的那个。然后调用 std :: string 的普通构造函数。

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.

您也可以使用C风格，但不推荐的方式：

You could also do it with a C-style, not recommended way:

std::string sName((char*) name);
