What is difference between ArrayList and List ?? Can you explain with example??

Answer 1

ArrayList is a deprecated version of List. With ArrayList it can contain objects of varying type, which is unsafe during iteration and therefore should not be used.

ArrayList Unsafe = new ArrayList();
List<int> Safe = new List<int>();

ArrayList.Add(666);
ArrayList.Add("beast"); // compiler WON'T complain
List.Add(666);
List.Add("beast"); // compiler error

foreach(int Value in Unsafe)... // runtime failure on "beast"
foreach(int Value in Safe)... // all good
