Base class from Windows Service

I'm trying to create a base class for a Windows Service. When creating, this is created automatically:

     public partial class Service1 : ServiceBase
     {
     public class Base    //added this to become a Base class
     {
        protected override void OnStart(string[] args)//generated code for Service
        {
          //a bunch of code here that I create
         }
     }
     }

And I Want to derive this class :

     public class Derived : Base
      {

       void Call(string[] args)
         {
            Call test = new Call();
            test.OnStart(args);///error says no suitable method found to override
         }
      }

The reason I want to do this is because this service will interact with multiple types of Databases and I want to have as much code reusable as possible, each one will have the same OnStart, OnStop etc... I've tried to use virtual, protected, public in the derived class. I can't change the generated code also.

How can I call the protected override OnStart? I will also have private members eventually and so I don't have to ask another question, if theres anything I need to know when calling those that would be helpful too..

After your edit: You have to inherit from ServiceBase. Simply creating a public class inside the scope of Service1 does not create inheritance. The correct definition is:

public class Derived : ServiceBase
{
    protected override void OnStart(string[] args)
    {
        //example
        int x = 1;

        //call the base OnStart with the arguments
        base.OnStart(args);
    }
}

Then, inside of your Program class, you would create such harness to run it:

var servicesToRun = new[]
{
    new Derived()
};
ServiceBase.Run(servicesToRun);

MSDN Reference here

The protected OnStart method requires the argument string[] args, based on your code above. You need to pass an array of arguments.
