Prove that an infinite set is semidecidible

Pregunta
I have been asked to prove that:
Being C an infinite set. Prove that C is semidecidable if and only if exists a total computable function that is injective and whose image is C.
I've read the wikipedia articles of computable function and recursively enumerable set and I saw these properties are true. But I have no idea how to start the proof.
Could you please help me?
Thanks in advance.
