什么是更好的设计？

Question

我手头有一个场景,正在进行一些设计讨论.用简单的话来区分它,考虑一个层次结构就像这样的公司----->客户------>订单(忽略订单如何产品的细节等)如果我要公开一个API与此合作,什么是更好的设计.

一个)

Dim comp As New Company
comp.GetInfo(123)
Dim cust As New Customer
cust.Name= "CustomerName"
comp.Add( cust)

b)

Dim custhand As Customerhandler
Dim cust As New Customer
cust.Name= "CustomerName"
custhand.AddCustomer(cust,123)  ''123 is CompanyID

Answer 1

我会和(A)一起去,但我会倾向于改变......

Dim comp As New Company
comp.GetInfo(123)

成...

Dim comp As Company = Company.Get(123)

(因此向Company类添加新的共享方法以返回Company的特定实例)
