如何在F＃中創建與.NET兼容的事件？

Question

我想從F＃類型發佈事件，但我希望它被視爲來自C＃或VB的事件。看來正確的方法是IEvent.create_HandlerEvent，但是這個函數並不存在於最新版本的F＃中。那麼現在做什麼是正確的方法呢？

Answer 1

事件是不是我的專長，但這個例子似乎在F＃1.9.6.16工作：

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
