    }
}

what this code should do, is take input from the user (the share's name and price), then store it in the array in the class and then retreive the info from the array.

Everything works, but the retrieving of multiple numbers from the array doesnt work well.

could you help me and tell me , why cant i store and retreive info from teh array in the class?

In your Add method, what do you think this code does, because it doesn't:

if ((size - index) == Delta) {
    shareName = new string[index + Increase_By];
    sharePrice = new int[index + Increase_By];
}

If this code ever executes you lose all the information you previously had.

ooh really!! i thought i was using dynamic arrays.

so should i remove that code completely?

edit.i tried it wont save even when i remove that code..

damn. why does it refuse to save"!!?!?
