IQueryable: reuse query in a different context

Question

Probably a question with a silly answer but: is there a way to define an IQueryable and then reuse it in different contexts afterwards?

Somethink like (Pseudocode):

public IQueryable<myItem> MyQuery()
{
   using(MyContext context = new MyContext())
   {
        return (from myItem in context.MyItems
                select ...);
   }
}

That is going to be used in a 'some' way as below.

public void MyMethod()
{
    using(MyContext context = new MyContext())
    {
        context.ExecuteQueryUnderContext(MyQuery());
    }

    using(MyContext context2 = new MyContext())
    {
        context2.ExecuteQueryUnderContext(MyQuery());
    }
}

Thanks

I would pass the context as a parameter for your Query method

public IQueryable<myItem> MyQuery(MyContext context)
{

        return (from myItem in context.MyItems
                select ...);
}

public void MyMethod()
{
    using(MyContext context = new MyContext())
    {
      var query = MyQuery(context);
    }
}
