Lists are used to create ordered collections whose capacity can increase (or reduce) dynamically. In the .NET type, List , this is achieved by starting with a default capacity of 4 and then doubling this to accomodate new elements as needed. Although arrays are also enumerable collections, their size cannot be changed once they have been created. Here's a simple example which illustrates how lists work: using System; using System.Collections.Generic; class Test { static void Main() { List list = new List {'A', 'B', 'C', 'D'}; Console.WriteLine(list.Capacity); // 4 // add another element list.Add('E'); Console.WriteLine(list.Capacity); // now 8 // remove 2nd element list.RemoveAt(1); // note that removing elements doesn't change capacity Console.WriteLine(list.Capacity); // still 8 // check if list contains 'D' Console.WriteLine(list.Contains('D')); // True // iterate through and print out remaining elements foreach(char c in list) Console.Write("{0} ", c); Console.ReadKey(); } }
