抽象声明中没有参数名称？ [英] No argument names in abstract declaration?

问题描述

这是F＃中抽象成员的典型声明：

This is the typical declaration of an abstract member in F#:

abstract member createEmployee : string -> string -> Employee

您可以定义参数类型，但不能定义其名称。如果没有名称，在实现接口时如何分辨每个参数是什么？换句话说，您如何知道该接口是否希望实现为1-或2-？

You define the argument types but not their names. Without names, how do you tell what each parameter is when you implement the interface? In other words, how do you know if the interface expects to be implemented as 1- or 2-?

1-   member this.createEmployee firstName lastName = ...
2-   member this.createEmployee lastName firstName = ...

我是从错误的角度看问题的（习惯于C＃）吗？

Am I looking the problem from a wrong perspective (being used to C#)?

推荐答案

那是什么：

abstract member createEmployee : firstName:string -> lastName:string -> Employee

？
