You have to build the string and execute it:

:exec 'e ' . foobar

Alternatively, you can use the expression-register and type:

:e ^R=foobar<cr>

where "^R" is control+R and <cr> is hitting <Enter> which works
for any evaluation, so you can do crazy things like

:e ^R=32*8<cr>.txt

would edit "256.txt".

You can read more at

:help :exec
:help c_CTRL-R_=
