是一个不好的做法重载的方法时，返回diferent类型？ [英] Is a bad practice to Return diferent types when overloading a method?

问题描述

由于这个例子：

Interface CustomersDao
    Function Get(ByVal Id As Integer) As Customer
    Function Get(ByVal Filter As Filter) As IList(Of Customer)
End Interface

Public Sub Main()
    Dim Customer As Customer = CustomersDao.Get(4)

    Dim Filter As New CustomersDao.Filter
    Filter.Category = 2
    Dim Customers As IList(Of Customer) = CustomersDao.Get(Filter)
End Sub

这是个不好的做法返回diferent类型相同的方法？

Is it a bad practice to return diferent types in the same method?

推荐答案

我会建议调用第二个 GETALL 。

现在，它并不明显，第二方法返回的集合。
你应该努力以确保您的类一样明显，尽可能不包含任何意想不到的惊喜。

Right now, it isn't obvious that the second method returns a collection.
You should strive to ensure that your classes are as obvious as possible and do not contain any unexpected surprises.
