Re: [Boost-users] Converting an std::vector to std::wstring

Hi: 
I carn't use that approach, the string is already constructed.
The string is part of a structure. I could contruct a temporary string,
and then assign the temporary string to the string in the structure,
will this reset the length of the string in the structure?

I suspect 5. None of the above.

The quickest and most efficent way to switch between two containers
which contain the same type is:

new_container container(old_container.begin(), old_container.end() )

so in this case:

wstring my_string(v.begin(), e.end());
