Using delegates

class Book

{

public Book(string id, string name, string author)

{

ID=id;

Name=name;

Author=author;

}

public string ID{ get; set;}

public string Name{get; set;}

public string Author{get; set;}

}

List listBook = new List();

listBook.Add(new Book("103","Code Complete","Steve MC"));

listBook.Add(new Book("101","Effective C++","Scott Meyers"));

listBook.Add(new Book("102","CLR Via C#","Jeff Prosise"));

 

listBook.Sort(

delegate(Book a, Book b)

{

return a.ID.CompareTo(b.ID);

});

 

Using Comparator

static in CompareBook(Book a, Book b)

{

return a.ID.CompareTo(b.ID);

}

 

listBook.Sort(CompareBook);

 

 

Using IComparable

class Book : IComparable

{

    public Book(string id, string name, string author)

    {

        ID = id;

        Name = name;

        Author = author;

    }

    public string ID { get; set; }

    public string Name { get; set; }

    public string Author { get; set; }

 

    public int CompareTo(object obj)

    {

        return ID.CompareTo(((Book)obj).ID);

    }

 

}
