If only I had known about your arrival, I would have come to the station to receive you.
But I think there should be could have instead of would have. We use that kind of conditional when we have regret about past.
If only he could have explained( but he wasn't able to) not If only he would have explained. and
If only I had passes the exam, I would have got the car.( but he didn't get the car)
In this sentence i think use of would have is correct.
But i am confused about 1 sentence. Don't know if i should use could have or would have.
