[英]F# - creating 100 objects into a List - most functional and idiomatic way
In F# what is the most functional and idiomatic way of creating or "newing up" 100 new objects into a List. 在F#中,创建或“新建”100个新对象到List中的最有用和最常用的方法是什么。
I guess for an example we could use DateTime as an example object. 我猜一个例子我们可以使用DateTime作为示例对象。
List.init 100 (fun x -> x * 2)
Alternatively, as a list expression: 或者,作为列表表达式:
[for i in 1..100 -> new System.DateTime()]
But I think this is less idiomatic. 但我认为这不太习惯。
I would consider using 我会考虑使用
[|for i in 1..100 -> new System.DateTime() |]
since you are working with mutable data. 因为您正在使用可变数据。
