c>有一个转换构造函数接受 const char * （ CStringT :: CStringT ）将 std :: string 转换为 CString 的过程非常简单：

CString has a conversion constructor taking a const char* (CStringT::CStringT). Converting a std::string to a CString is as simple as:

std::string stdstr("foo");
CString cstr(stdstr.c_str());

这适用于UNICODE和MBCS项目。如果 std :: string 包含嵌入的 NUL 字符，那么必须使用具有长度参数的转换构造函数： p>

This works for both UNICODE and MBCS projects. If your std::string contains embedded NUL characters you have to use a conversion constructor with a length argument:

std::string stdstr("foo");
stdstr += '\0';
stdstr += "bar";
CString cstr(stdstr.c_str(), stdstr.length());
