我想从发布的F＃类型的事件，但我希望它被看作是从C＃或VB的事件。看来，做正确的方式，它曾经是IEvent.create_HandlerEvent，但是这个功能不能在F＃的最新版本存在。那么，什么是现在就这样做了正确的方法是什么？

I am trying to publish an event from an F# type, but I want it to be seen as an event from C# or VB. It seems that the correct way to do it used to be IEvent.create_HandlerEvent, but this function doesn't exist in the newest version of F#. So what is the correct way to do it now?

推荐答案

事件是不是我的专长，但这个例子似乎工作在F＃1.9.6.16：

Events are not my forte, but this example seems to work on 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
