C++ wstring to file instead of string

Question

I have a simple logger class which I tried to turn into accepting and outputting wstrings instead strings.

header:

#include <fstream>
using namespace std;

class CLog 
{
  public:
    CLog(wstring filename);
    ~CLog();
    void WriteString(string uString);
  private:
    fstream m_stream;
};

cpp:

#include "stdafx.h";
#include "log.h";

CLog::CLog(wstring uPath) 
{
  m_stream.open(uPath);
}
void CLog::WriteString(string uString)
{
  m_stream << uString.c_str() << endl;
}
CLog::~CLog()
{
  m_stream.close();
}

Can anybody suggest what I should use instead of fstream? I tried using wstringstream, but it did not even have .open to output it to file, so I thought that is the wrong approach.

I would like to keep the behaviour that it immediately writes to a file.

Answer 1

I use "wofstream" instead of "fstream" now, and it works perfectly.
