How I can convert wstring to String? I want convert wstring to stringThe first thing you need to get straight is that "string" and "String" are not the same. "string" is (usually) std::string from the C++ library, while "String" is typically System::String from the .NET framework.M...
std::wstring_convert<std::codecvt_utf8<wchar_t>> conv; std::string narrowStr = conv.to_bytes(str); { std::ofstream ofs ("c:\\test.txt"); ofs << narrowStr; } std::wstring wideStr = conv.from_bytes(narrowStr); { std::locale::global(std::locale("Chinese-simplified")); ...
If you're using VC++ 2010, another option is to use the newwstring_convertclass: #include <locale> #include <cvt/wstring> ... typedef std::codecvt<wchar_t, char, std::mbstate_t> cvt_t; CString str = L"Testing."; std::string s = stdext...
GetString(); // wsrStd = L"Test" // std::string to CString / std::wstring strStd = "Test 2"; strMfc = strStd.c_str(); // strMfc = L"Test 2" wstrStd = A2W(strStd.c_str()); // ** Conversion Macro: wstrStd = L"Test 2" ** // std::wstring to CString / ...

您好,这个问题也是我当时的一个疑惑,根据我个人的理解以及查看其转换代码,在 std::u16string 与 std::u8string 之间转化时并没有用到 std::locale,所以理论上来说,std::locale 确实并不是必须的。 但是由于 std::codecvt 类将析构设计成 protected,所以 std::codecvt 类的对象,只能由 std::locale 来管理资...
error: cannot convert 'std::string' {aka 'std::__cxx11::basic_string<char>'} to 'String' 出现原因: Boards Manager 中将 Arduino ESP32 板软件更改为版本 3.x 则会出现该问题。这是新版本(C++ STL) 转换为 (Arduino WString)出现的问题。
