How to pass Dbset object as a parameter to any user define function in entity framework code first?

I want to pass Dbset Object to my method.

This is my Method:

public static class MyClass
    {
       public static Floor ReturnObject(this DbSet<Floor> floor, int Id)
        {
           var context = floor.passContext() as MyDBContext;
           var data = context.floors.Where(a =>a.Id == Id).FirstOrDefault();
           return ad;
        }
     }

   public class MyDBContext: DbContext
    {
          public DbSet<Floor> floors { get; set; }
    }

public static DbContext passContext<TEntity>(this DbSet<TEntity> dbSet)
            where TEntity : class
        {
                 //code....
        }

Now i want to use my method of static class MyClass that is ReturnObject.

I want to use ReturnObject method in my Controller.

I know i can declare it as private member like this in my controller:

This is my controller:

public class MyController
{
       private DbSet<Floor> floor;//but is this a good way???
         public ActionResult Index(int Id)
            {
              var data=MyClass.ReturnObject(????,Id)//what should come in place of question mark??
            }
}

How should i pass my First Parameter to ReturnObject Method???

Change your ReturnObject method. It should only take Id as parameter and filter data than return object of Floor.

public static Floor ReturnObject(int Id)
{
  using(MyDBContext context = new  MyDBContext())
  {
       var data = context.floors.Where(a =>a.Id == Id).FirstOrDefault();
       return ad;
   }
}

And when you call it than only pass id as paramter

var data=MyClass.ReturnObject(Id);

This will return object of floor which will be stored in data.
