In „[post id=“4996″]Strings alphabetisch sortieren mit LINQ[/post]“ habe ich gezeigt, wie man ganz leicht Zeichenketten sortieren kann. In diesem Beispiel möchte ich zeigen, wie man Objekte komplexerer Datentypen sortieren kann. Mit LINQ geht das auch wieder sehr leicht von der Hand.
Datentyp: Person.cs

public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
} |
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
public int Age { get; set; }
