How to read Organisation Business Closure in MS CRM Using C#

Some time in CRM one needs to read Organisation Business Closure in code  to know whether any organisation level holiday is defined there or not.

For Ex: In scheduler services which needs to only run on  the days business is ON.

Below is the C# code snippet that can be utilise to achieve such functionality:

/////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

  public static Boolean ISTodayOrgHolidayInOrgBusinessClosure(DateTime datetime, IOrganizationService service)

        {

            Guid orgId = ((WhoAmIResponse)service.Execute(new WhoAmIRequest())).OrganizationId;

            Entity org = service.Retrieve("organization", orgId, new Microsoft.Xrm.Sdk.Query.ColumnSet("businessclosurecalendarid"));

            QueryExpression query = new QueryExpression("calendar");

            query.ColumnSet = new ColumnSet(true);

            query.Criteria = new FilterExpression();

            query.Criteria.AddCondition(new ConditionExpression("calendarid", ConditionOperator.Equal, org["businessclosurecalendarid"].ToString()));

            EntityCollection OrgBusinessClosureCalendarCollection = service.RetrieveMultiple(query);

            if (OrgBusinessClosureCalendarCollection.Entities.Count> 0)

            {

                Entity BusinessClosureCalendar = OrgBusinessClosureCalendarCollection.Entities[0];

                if (BusinessClosureCalendar != null)

                {

                  foreach (Entity closure in BusinessClosureCalendar.GetAttributeValue<EntityCollection>("calendarrules").Entities)

                    {

                        DateTime intervalStart = closure.GetAttributeValue<DateTime>("effectiveintervalstart");

                        DateTime intervalEnd = closure.GetAttributeValue<DateTime>("effectiveintervalend");

                        if ((DateTime.Now >= intervalStart) && (datetime <= intervalEnd))

                        {

                            return true;   //return is holiday

                        }

                    }

                }

            }

            return false;

        }
