C# Console Application phonebook arrays

I am told to design a phonebook which will use 2D array to store Name and Phone numbers in type : string . It should have the functions like add, remove, print methods.

I am yet struggling in this array. I do not know how to fill the whole of array members with "none" whenever a record for name is not present and "000" for its number.

by default, i need it to have this printed: (20 records of none 000) none 000 none 000 none 000 ... none 000 none 000 none 000

I came up with:

string[,] db = new db[20,2];

I am not sure though if its the right, but I just want a 2D array which has 20 rows and 2 columns.

Then I wanna use for or foreach loop to fill the elements by none and 000:

for (int i=0; i<db.Length/2; i++)
     for (int j=0; j<db.Length/20; j++)

Could you help me with filling that? Thanks

The loop you're looking for to initialize the array would be:

for (int i = 0; i < 20; ++i)
{
    db[i,0] = "none";
    db[i,1] = "000";
}

class Address {
    public string Name {get; set; }
    public string Phone {get; set; }
}

List<Address> addressBook = new List<Address>();

// Do stuff with your list

No need to use an array.
