Constructors or Methods

Question

Hi there

I've got a question about C#. I've seen a lot of projects with the two examples:

• The first one get an existing Order with Order o = new Order(1);
• The other get an existing Order with Order o = OrderManager.GetOrderById(1);

The first used an constructor the other an method by an other class. Is that the "programming-style" of a programmer or a C# rule?

I hope you understand what I tried to ask...

Regards,
