I want to order object in List<> alphabetically.
How do I order this list alphabetically according to FamilyName? The result should be (2,1,3)

List<User>uList=new List<User>;
User u1=new User;
u1.FirstName="John";
u1.FamilyName="Johnson";
uList.add(u1);
User u2=new User;
u2.FirstName="Howard";
u2.FamilyName="Anderson";
uList.add(u2);
User u3=new User;
u3.FirstName="Jim";
u3.FamilyName="Reagan";
uList.add(u3);

You can use linq to sort a list of objects

var orderedList = uList
           .OrderBy(x => x.FamilyName) .ToList();

Another possibility:

The following code helps in sorting list of objects based on some propertys value.
Source: http://cherupally.blogspot.com/2009/04/how-to-sort-list-of-objects-in-c.html

Console.WriteLine(Sorted list, by name);
uList.Sort(delegate(Person p1, Person p2) { return p1.FamilyName.CompareTo(p2.FamilyName); });
uList.ForEach(delegate(User p) { Console.WriteLine(String.Format({0} {1}, p.FamilyName, p.FirstName)); });
