Sorting a List of objects in C#

Question

public class CarSpecs
{
  public String CarName { get; set; }

  public String CarMaker { get; set; }

  public DateTime CreationDate { get; set; }
}

Answer 1

I would just use the build in List.Sort method. It uses the QuickSort algorithm which on average runs in O(n log n).

This code should work for you, I change your properties to auto-properties, and defined a static CompareCarSpecs method that just uses the already existing DateTime.CompareTo method.

class Program
{
    static void Main(string[] args)
    {
        List cars = new List();
        cars.Sort(CarSpecs.CompareCarSpecs);
    }
}

public class CarSpecs
{
    public string CarName { get; set; }
    public string CarMaker { get; set; }
    public DateTime CreationDate { get; set; }

    public static int CompareCarSpecs(CarSpecs x, CarSpecs y)
    {
        return x.CreationDate.CompareTo(y.CreationDate);
    }
}

Hope this helps.
