Question

我有一个Person，我希望使用属性初始值设定项初始化Name，使用构造函数初始化Age。

C＃版

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }

    public Person(int age)
    {
        Age = age
    }
}

var person = new Person(20) { Name = "Alex" };

我试过F＃：

尝试1：语法无效

type Person = {
    Name: string
    Age: int
} with 
    static member create (age: int): Person =
        { this with Age = age }: Person

尝试2：语法无效

type Person =
    member val Name: string
    member val Age: int

    new(age: int)
        this.Age = 13

Answer 1

应该像

一样简单

type Person(age:int) =
    member val Name = "" with get, set
    member val Age = age with get, set

let person = Person(20, Name = "Alex")

对象初始化器+属性初始化器（从C＃到F＃）
