If you know the index in that case you can access it through it.

No ya...... Let us consider im having 5 elements in a list such as {3,6,8,2,9,1}.If i want 8 means,straight a way i have to take it,without using Linq and for loop...... Which means i need a minimum coding to get a specific item from a collection.

In that case you can define "indexer" on your collection. Accessing object by index should be more efficient than accessing it any other way.

Solution 2

XML

List<int> coll = new List<int> { 3, 6, 8, 2, 9, 1 };
          int searchNo = 8;
          int result = coll.Find(delegate(int item)
          {
              return searchNo == item;
          });
          Console.WriteLine(result);

let us consider im storing collection of objects in a list.Each and every object stores persons Information.These objects wil contain a member variable called name.while searching for the specific person,i just give a Person name ,the collection has to return the corresponding persons object. And this has to be done without using for loop and without using Linq........
