Simple use of C # quartz.net timed tasks

Recently made a software that performs tasks on a timed basis.

When the task is executed, the log is logged with log4net and if there is an exception to the execution of the task, the message is sent to the specified object.

What I do is to perform a task at 9 and 16 points per day to record this:

First, get quartz.net,

You can actually use the vs2015 nuget Manager to download.

I made a quartzhelper, but in the main program, I still need other code.

Here is the code for Quartzhelper:

The approximate process is this:
Instantiate a plan factory object through Ischedulerfactory, and use a factory to instantiate a scheduler plan object,

Then instantiate a Task object job, which is the object that defines the task content, and needs to pass in a class that implements the Ijob interface, where I use generics,

Next, you need an object that can trigger the task, there are two kinds of

One is the Itrigger, which is used for specification time interval, after the plan starts, will trigger the execution task according to the interval time value;

The other is Icrontrigger, which is the time that is executed through the CRON expression specification, which triggers the execution of a task after the scheduled start, if the time meets the specified time.

Finally, the job and trigger are passed into the Plan scheduler, the plan begins.

The bottom-most example of a task is an example,

The Ijob interface and the Execute method must be implemented.

If you need to invoke data outside of the class within the Execute method, I am calling the myjob by defining a method of the static class in the project.

Code for program start plan:

string cronexpression = "0 0 9,16 * *?"; = = This refers to 9 points and 16 points per day to perform tasks
quartzhelper.executebycron<myjob> (cronexpression); = = This is called cron scheduling method

Simply say the cron expression,

"0 0 9,16 * *? ",

Order from left to right

0: Seconds

0: minutes

9,16: Hours, comma-delimited
