属性值

A TimeSpan object that specifies how long the vacuum process is allowed to run.

备注

The interval specifies the length of the vacuuming period, and cannot exceed 24 hours.

Vacuuming schedules cannot overlap. If schedules overlap, Notification Services stops the earlier vacuuming process before the later one starts.

示例

The following examples show how to create a schedule for removing obsolete data and then add the schedule to the collection of vacuum schedules for the application:

VacuumSchedule vacuumSchedule1 = new VacuumSchedule(
    myApplication, "1");
vacuumSchedule1.StartTime = new TimeSpan(23, 0, 0);
myApplication.VacuumSchedules.Add(vacuumSchedule1);

Dim vacuumSchedule1 As VacuumSchedule = _
    New VacuumSchedule(myApplication, "1")
vacuumSchedule1.StartTime = New TimeSpan(23, 0, 0)
myApplication.VacuumSchedules.Add(vacuumSchedule1)
