Conversion of wchar_t* to string [duplicate]

Question

How can I convert an wchar_t* array to an std::string varStr in win32 console.

Answer 1

Use wstring, see this code:

// Your wchar_t*
wchar_t* txt = L"Hello World";
wstring ws(txt);
// your new String
string str(ws.begin(), ws.end());
// Show String
cout << str << endl;

Answer 2

You should use the wstring class belonging to the namespace std. It has a constructor which accepts a parameter of the type wchar_t*.

Here is a full example of using this class.

wchar_t* characters=L"Test";
std::wstring string(characters);

You do not have to use a constructor containing String.begin() and String.end() because the constructor of std::wstring automatically allocates memory for storing the array of wchar_t and copies the array to the allocated memory.
