In C# 3.0 for ,Removiing duplicates I can use
int[] ints={1,1,2,34,5,6,7,5,11,13};
List<int> integes = new List<int>();
List<int> filter = new List<int>();
integes.AddRange(ints);
filter = integes.Distinct().ToList();
filter.ForEach((i)=> { Console.WriteLine(i); });
Is similar shortcut method is available in ASP.NET 2.0 .
