return a CStringList

My program is as follows:
CStringList CMyClass::Func() const
{
      CStringList aStringList;
                  CString aString = "Hello";
                  aStringList.AddTail(aString);
                  return aStringList;
}

But the following error occured:
error C2664: 'CStringList::CStringList' : cannot convert parameter 1 from 'class CStringList' to 'int'

why? Can I return a CStringList? Thank you very much!

No, the CStringList does not have a copy constructor so you can not return a copy from the function. You need to pass in a reference to the list you want to manipulate to the function:

void CMyClass::Func(CStringList& aStringList) const
{
  aStringList.AddTail("Hello");
}
