Constructor Injection to access service

Question

Is there a better way to consume a service in mvvmcross by constructor injection? For example, I have my object in a plugin implementation

public class MyObject : IMyObject
{
   public MyObject (int id) 
   {
      _id = id;
   }
}

and want to consume it somewhere the portable core (in the buisness layer) like this :

public void ConsumeTheService()
{
    int i = 50;
    var myObject = this.GetService<IMyObject>(i);
}

Actually, I only use a setter to get my id back in the implementation.

Following your update... if you are asking about how to get:

    var myObject = this.GetService<IMyObject>(50);

and for this to return an object which is initiaised as new MyObject(50)

then I would instead recommend that you implement an interface

public interface IMyObjectFactory
{
    IMyObject CreateMyObject(int i);
}

with an implementation:

public class MyObjectFactory : IMyObjectFactory
{
    public IMyObject CreateMyObject(int i)
    {
        return new MyObject(i);
    }
}

you can then register this IMyObjectFactory with IoC
