1. Your class has to inherit IComparable
2. Implement IComparable's CompareTo method
3. After your generic list of objects is built, then call the lists .Sort method.
In this code I needed the LmrMed's serviceDate sorted in descending order. The Sort method does not create a new list, it changes the order of the nodes in the current list.
I found this article helpful in learning about c# generic list sorting: http://www.codedigest.com/Articles/CSHARP/84_Sorting_in_Generic_List.aspx
public class LmrMed : IComparable<LmrMed>
{
public int recId { get; set; }
public string medText { get; set; }
public DateTime? startDate { get; set; }
public DateTime? endDate { get; set; }
public DateTime serviceDate { get; set; }
public LmrMed(int recId, string medText, DateTime startDate, DateTime endDate, DateTime serviceDate)
{
this.recId = recId;
this.medText = medText;
this.startDate = startDate;
this.endDate = endDate;
this.serviceDate = serviceDate;
}
public int CompareTo(LmrMed lm)
{
return lm.serviceDate.CompareTo(this.serviceDate);
}
List<LmrMed> lmrMeds = GetMeds(_mrn);
lmrMeds.Sort();
