Come interrogare una lista calendario di SharePoint

Un esempio di come interrogare una lista di tipo calendario di SharePoint 2010 in C#

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      using (SPSite site = new SPSite("http://sharepoint2010.sgart.local"))
      {
        using (SPWeb web = site.OpenWeb())
        {
          SPList list = web.GetList(web.ServerRelativeUrl.TrimEnd('/') + "/Lists/Calendar");
          SPListItemCollection items = list.Items;
          foreach (SPListItem item in items)
          {
            Console.WriteLine("ID: " + item.ID.ToString());
            Console.WriteLine("ContentType: " + item[SPBuiltInFieldId.ContentType].ToString());
            Console.WriteLine("Title: " + item.Title);
            Console.WriteLine("StartTime: " + item[SPBuiltInFieldId.StartDate].ToString());
            Console.WriteLine("EndTime: " + item[SPBuiltInFieldId.EndDate].ToString());
            Console.WriteLine("AllDayEvent: " + item[SPBuiltInFieldId.fAllDayEvent].ToString());
            Console.WriteLine("Recurrence: " + item[SPBuiltInFieldId.fRecurrence].ToString());
            Console.WriteLine("RecurrenceData: " + (item[SPBuiltInFieldId.RecurrenceData] == null ? "" : item[SPBuiltInFieldId.RecurrenceData].ToString()));
            Console.WriteLine("EventType: " + item[SPBuiltInFieldId.EventType].ToString());
            Console.WriteLine("UID: " + (item[SPBuiltInFieldId.UID] == null ? "" : item[SPBuiltInFieldId.UID].ToString()));
            Console.WriteLine("RecurrenceID: " + (item[SPBuiltInFieldId.RecurrenceID] == null ? "" : item[SPBuiltInFieldId.RecurrenceID].ToString()));
            Console.WriteLine("EventCanceled: " + (item[SPBuiltInFieldId.EventCanceled] == null ? "" : item[SPBuiltInFieldId.EventCanceled].ToString()));
            Console.WriteLine("Duration: " + item[SPBuiltInFieldId.Duration].ToString());

            Console.WriteLine("Location: " + (item[SPBuiltInFieldId.Location] == null ? "" : item[SPBuiltInFieldId.Location].ToString()));
            Console.WriteLine("------------------------------------");
          }

        }
      }
      Console.ReadKey();
    }
  }
}
da un risultato simile al seguente

in questo caso l'ho trattata come una normale lista e come puoi vedere gli eventi ricorrenti non vengono spittati, ma compaiono come unico evento dove tutti i dettagli si trovano in altri campi, come ad esempio RecurrenceData.

Per elencare tutti gli eventi di un calendario, comproso quelli ricorrenti, bisogna costruire una query CAML utilizzando l'oggetto SPQuery impostando le proprietà ExpandRecurrence e CalendarDate:

C#

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;

namespace ConsoleApplication1
{
  class Program
  {
    static void Main(string[] args)
    {
      using (SPSite site = new SPSite("http://intranet.contoso.com"))
      {
        using (SPWeb web = site.OpenWeb())
        {
          SPList list = web.GetList(web.ServerRelativeUrl.TrimEnd('/') + "/Lists/Calendar");
          SPQuery query = new SPQuery();
          query.Query = @"<Where>
            <DateRangesOverlap>
              <FieldRef Name='EventDate' />
              <FieldRef Name='EndDate' />
              <FieldRef Name='RecurrenceID' />
              <Value Type='DateTime' IncludeTimeValue='TRUE'>
                <Month />
              </Value>
            </DateRangesOverlap>
          </Where>";  // sintassi caml per interrogare una lista di tipo calendario ed ottenere tutti gli eventi di un mese
          query.CalendarDate = DateTime.Today; // passo la data corrente per selezionare il mese
          query.ExpandRecurrence = true;  //faccio in modo che gli eventi ricorrenti vengano espansi
          SPListItemCollection items = list.GetItems(query);
          foreach (SPListItem item in items)
          {
            Console.WriteLine("ID: " + item.ID.ToString());
            Console.WriteLine("ContentType: " + item[SPBuiltInFieldId.ContentType].ToString());
            Console.WriteLine("Title: " + item.Title);
            Console.WriteLine("StartTime: " + item[SPBuiltInFieldId.StartDate].ToString());
            Console.WriteLine("EndTime: " + item[SPBuiltInFieldId.EndDate].ToString());
            Console.WriteLine("AllDayEvent: " + item[SPBuiltInFieldId.fAllDayEvent].ToString());
            Console.WriteLine("Recurrence: " + item[SPBuiltInFieldId.fRecurrence].ToString());
            Console.WriteLine("RecurrenceData: " + (item[SPBuiltInFieldId.RecurrenceData] == null ? "" : item[SPBuiltInFieldId.RecurrenceData].ToString()));
            Console.WriteLine("EventType: " + item[SPBuiltInFieldId.EventType].ToString());
            Console.WriteLine("UID: " + (item[SPBuiltInFieldId.UID] == null ? "" : item[SPBuiltInFieldId.UID].ToString()));
            Console.WriteLine("RecurrenceID: " + (item[SPBuiltInFieldId.RecurrenceID] == null ? "" : item[SPBuiltInFieldId.RecurrenceID].ToString()));
            Console.WriteLine("EventCanceled: " + (item[SPBuiltInFieldId.EventCanceled] == null ? "" : item[SPBuiltInFieldId.EventCanceled].ToString()));
            Console.WriteLine("Duration: " + item[SPBuiltInFieldId.Duration].ToString());

            Console.WriteLine("Location: " + (item[SPBuiltInFieldId.Location] == null ? "" : item[SPBuiltInFieldId.Location].ToString()));
            Console.WriteLine("------------------------------------");
          }
        }
      }
      Console.ReadKey();
    }
  }
}
in questo caso gli eventi ricorrenti vengono espansi, compaiono come singoli item e le date di inizio e fine vengono settate correttamente:

Nella query CAML oltre al tag Month c'è anche il tag Year, Week, Day e Today.

Vedi anche DateRangesOverlap Element (Query).
