Dynamically build an array for web service

Question

I\'m using C# and asp.net to query a web service.

The user will enter the number of guests and then I need to add that number of guests to the web service call. Creati

Answer 1

All the other answers have suggested using List and normally I'd agree - but in this case there's really no need as it seems you know the size beforehand:

Guest[] guests = new Guest[numberOfGuests];
for (int i=0; i < numberOfGuests; i++)
{
    Guest guest = new Guest();
    // Fill in information about the guest here
    // based on the web form
    guests[i] = guest;
}

That's not to say you shouldn't use a List if that's more convenient in any way - it's just that the (probably) biggest benefit of using a List is that you don't need to know the size in advance. As that's not relevant here (unless I'm missing something) there's not as much reason to use a list.
