Search a 1D array in a 2D array

Hi would like to search all rows in a 2D array to find whether the particular row I'm searching for is in the 2-D array and return the row index of the 1-D array. How do I do it?

For example from a CSV file consisting of Name and contact of several people, I want to search if the name and contact keyed in by me is there in the list. 

Thanks
