通过C#for CRM 2015中的插件或简单控制台应用程序删除或删除日历规则"Time Off Rule"

Question

我有以下问题:

我需要从属于"设备"的特定日历的日历规则中删除或删除"超时规则".需要这样做,以便设备可用于在服务日历上进行安排.

不知何故,我无法理解如何做到这一点.

我能够检索需要删除的日历规则对象,但下一步就是我.

请小心告诉我:

1. 可以通过C#(SDK)完成

2. 任何类似的Web资源或代码部分.

以下代码给出了错误

您尝试删除的对象与另一个对象关联,无法删除.

//equip is of Equipment type and is already initialized 
CrmEarlyBound.Calendar cal = (CrmEarlyBound.Calendar)svc.Retrieve("calendar", equip.CalendarId.Id, new ColumnSet(true));
Console.WriteLine("Got the user calendar");
List<CalendarRule> calendarRules = cal.CalendarRules.ToList();
Console.WriteLine("Got the calendar rules " +  cal.CalendarRules.ToList().Count);
foreach (CalendarRule cr in cal.CalendarRules)
{
   if (cr.Description == "Time Off Rule" && cr.StartTime.Value>=DateTime.Now)
   {
       Console.WriteLine(cr.StartTime);
       Calendar calI = (Calendar)svc.Retrieve(cr.InnerCalendarId.LogicalName, cr.InnerCalendarId.Id, new ColumnSet(true));
       //svc.Delete(cr.InnerCalendarId.LogicalName, cr.InnerCalendarId.Id);
    }
 }

你快到了。必须删除calendarrules集合并更新calendar实体。

public static void ClearCalenderRules(IOrganizationService service, Guid bookableResourceId, DateTime startDate, DateTime endDate)
{
    using (var context = new CrmServiceContext(service))
    {
        var bookableResource = context.BookableResourceSet.Where(b => b.Id == bookableResourceId).FirstOrDefault();

        if (bookableResource?.CalendarId != null)
        {

            Entity entity = service.Retrieve("calendar", bookableResource.CalendarId.Id, new ColumnSet(true));
            EntityCollection entityCollection = (EntityCollection)entity.Attributes["calendarrules"];

            int num = 0;
            List<int> list = new List<int>();
            foreach (Entity current in entityCollection.Entities)
            {
                DateTime dateTime2 = Convert.ToDateTime(current["starttime"]);
                if (dateTime2 >= startDate && dateTime2 <= endDate)
                {
                    list.Add(num);
                }

                num++;
            }

            list.Sort();
            list.Reverse();

            for (int i = 0; i < list.Count; i++)
            {
                entityCollection.Entities.Remove(entityCollection.Entities[list[i]]);
            }

            entity.Attributes["calendarrules"] = entityCollection;
            service.Update(entity);
        }
    }
}
