Question

How do i programatically pass in arguments to OnStart method of a Service, which I further need to propagate to the Elapsed event of the Timer inside the service?

Answer 1

At the simplest level: when you call ServiceBase.Run, you get to give it the service instances to execute. Simply declare this as a public property on your service, and assign prior to calling Run:

        Service1 myService = new Service1();         myService.SomeProp = 1;         ServiceBase.Run(myService); 

Then read SomeProp in your service:

    public int SomeProp { get; set;}     protected override void OnStart(string[] args)     {         int prop = SomeProp;     } 

You can also use the service args, but that is from the external caller (service registration) – not programatically (per the question).
