类型转换问题!

[lixang000]

void CMyDoc::OnFileOpen()
{
......
if(dlg1.DoModal()==IDOK)
{
filename=dlg1.GetPathName();
}

std::wstring ws;
ws=filename.GetBuffer();
std::ofstream outFile("a.txt");
outFile<<filename.GetBuffer()<<std::endl;
outFile<<ws<<std::endl;//加上此话则出错!
outFile.close();
}
error C2679: 二进制“<<”: 没有找到接受“std::wstring”类型的右操作数的运算符(或没有可接受的转换)
估计是要重载<<
请高手指点改错!

要用std::wofstream

[珍惜生命远离CPP]

ofstream 改为
basic_ofstream<wchar_t>

[jingzhongrong]

typedef basic_ofstream<wchar_t, char_traits<wchar_t> > wofstream;
