• May 22, 2020

1. An appointment recurs every 2 weeks, on Monday and Wednesday. It occurs 15 times.

   C#

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly;
   apt.RecurrenceInfo.Start = apt.Start;
   apt.RecurrenceInfo.Periodicity = 2;
   apt.RecurrenceInfo.WeekDays = WeekDays.Monday | WeekDays.Wednesday;
   apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount;
   apt.RecurrenceInfo.OccurrenceCount = 15;
   

   VB.NET

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly
   apt.RecurrenceInfo.Start = apt.Start
   apt.RecurrenceInfo.Periodicity = 2
   apt.RecurrenceInfo.WeekDays = WeekDays.Monday Or WeekDays.Wednesday
   apt.RecurrenceInfo.Range = RecurrenceRange.OccurrenceCount
   apt.RecurrenceInfo.OccurrenceCount = 15
   

2. An appointment occurs every fourth week on weekends. Infinite (no end date).

   C#

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly;
   apt.RecurrenceInfo.Start = apt.Start;
   apt.RecurrenceInfo.Periodicity = 4;
   apt.RecurrenceInfo.WeekDays = WeekDays.WeekendDays;
   apt.RecurrenceInfo.Range = RecurrenceRange.NoEndDate;           
   

   VB.NET

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly
   apt.RecurrenceInfo.Start = apt.Start
   apt.RecurrenceInfo.Periodicity = 4
   apt.RecurrenceInfo.WeekDays = WeekDays.WeekendDays
   apt.RecurrenceInfo.Range = RecurrenceRange.NoEndDate
   

3. An appointment occurs every Friday for 24 days.

   C#

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly;
   apt.RecurrenceInfo.Start = apt.Start;
   apt.RecurrenceInfo.Periodicity = 1;
   apt.RecurrenceInfo.WeekDays = WeekDays.Friday;
   apt.RecurrenceInfo.Range = RecurrenceRange.EndByDate;
   apt.RecurrenceInfo.End = apt.RecurrenceInfo.Start.AddDays(24);
   

   VB.NET

   
   apt.RecurrenceInfo.Type = RecurrenceType.Weekly
   apt.RecurrenceInfo.Start = apt.Start
   apt.RecurrenceInfo.Periodicity = 1
   apt.RecurrenceInfo.WeekDays = WeekDays.Friday
   apt.RecurrenceInfo.Range = RecurrenceRange.EndByDate
