Task management algorithm in C#

i am looking for efficient task management fo C#

what i mean by task management is executing pre-defined interval time of task.

Example: task a needs to be run every 1 mins task b needs to be run every 3 mins task c needs to be run every 5 mins

these tasks can be added and removed in arbitary time...

And the task that i mentioned can be 100000 or more... The task will be executed forever until it is removed...

Do u guys familiar with this kind 开发者_StackOverflowof algorithm? I am thinking to implement in either c# or php....

Thanks

I would suggest using the open-source Quartz.Net as it does everything you want. There is really no good reason to roll your own for something like this.
