Ok, if you are dead set on doing it this way, you need an array of arrays. each element of the array is another array which holds all of the info.

Code:
    string[][] contacts = new string[20][];
    for ( int i = 0; i < contacts.Length; ++i )
    {
        contacts[ i ] = new string[ ] { "John Doe", "123 Fake Street", "Vista", "CA", "92084" };
    }
Now you have an array of arrays, and it is just terrible. So, each entry in the array is another array which has all of the information regarding a "contact".
