Are internal string states analogues of internal particle states?

it is something said that in string theory elementary practical correspond to mode of vibration of a string.
likewise in QFT , several particle field take their values in higher dimensional space, the basis elements of which or otherwise some, subrepresentation could be seen as distinct practice , e.g. the electron and the positron and may be even practices with different spin could be regarded as different particles.
are this situations analogous ? can string theory be seen as a QFT in which there is a quantum field with an infinite dimensional internal structure space ( rather than the4D of a Dirac spinor ) , the basis element of which can be imagined as vibrational modes of a spring ? or is that very far beside the mark?
I hope it help us
