Hello,

Is there any difference between ArrayList and List<object> ? Which
one should I use ?

Thanks.
 
ArrayList (donet 1.1) is obsolete in dotnet 2.0
You must use List<T>
more performant than ArrayList
access to element is done in constant time

LinkedList<T> : time to access an element depend of the number of elements
but add is done in constant time

ArrayList is not obsolete in .NET 2, but it is nearly always a poor choice.
List<T> is a superior alternative since you can specify exactly what your
list contains and not have to cast back from object when reading from the
list.

In any container with O(n) elements the most we can have is the
O(log(n)) access time.
