.net - 如何在F#中创建.NET兼容事件？

Question

我正在尝试发布F#类型的事件，但我希望将其视为C#或VB中的事件。似乎正确的方法曾经是IEvent.create_HandlerEvent，但是最新版本的F#中不存在此函数。那么现在正确的方法是什么？

Answer 1

事件不是我的专长，但是此示例似乎适用于F#1.9.6.16:

namespace EventExample
open System
type MyEventArgs(msg:string) =
    inherit EventArgs()
    member this.Message = msg

type MyEventDelegate = delegate of obj * MyEventArgs -> unit

type Foo() = 
    let ev = new Event<MyEventDelegate, MyEventArgs>()

    member this.Ping(msg) =
        ev.Trigger(this, new MyEventArgs(msg))

    [<CLIEvent>]
    member this.GotPinged = ev.Publish
