QUARTZ. NET is a scheduled task framework and the quartz.net task framework.

QUARTZ. NET is a scheduled task framework and the quartz.net task framework.

Quartz. NET-1.0.3 file (this is an old version and now has a new version. The usage seems different)

First, add the Common. Logging. dll file and the Quartz. dll file under the bin/1.0.3/Release/Quartz/directory under the Quartz. NET-3.5 file and then add references. Introduce connected files into the project

NET is a concept of a scheduled task framework: planner: ischedjob; Work IJob; Trigger: Trigger; we first get an isched and then create a job (IJob ), throw the task to the planner and tell it under what conditions (Trigger) the code of the task to be scheduled to be executed can be written to the Execute method of the IJob interface, when the time comes, the Execute method will be called. CrondTrigger is a trigger set through the Crond expression, and simple triggers such as SimpleTrigger.
