Declaring a arrays of objects dynamically

[winpoorni]

Hi all, I need to create arrays of object dynamically. for example class Pesron; Person[] p=new Person[10]; it creates 10 objects ob type person. I don't know the exact number of objects. i have to specify it in run time Thanks n Regards, Ramya.R

Try the ArrayList class.

Hello Ramya, Do you know link list data structure. It will allow you to insert any number of object.

Person[] p = new Person[n] Where n is a varible with the number that you need. Alternatively if it's the case that even at runtime you don't know how many you will need then use the ArrayList class.

A few others have replied here saying to use ArrayList. That is fine. If you're using .NET 2.0, you can use the System.Collections.Generic.List object to store your Person objects in a strongly-typed fashion (which ArrayList will not do). For example:

using System.Collections.Generic;
...
List< Person > persons = new List< Person >();
persons.Add(somePerson);
persons.Add(5); // compile-time error: persons can only contain Person objects. This is something ArrayList will NOT give you, hence the benefit of using List

Thanks Judah Himango .. Your coding was very useful to me. Thanks a lot Thanks n Regards, Ramya.R

Do you know that when u declare any object it will just declare reference not allocate memory for that. Now you can use this concept for link list.
