如何在F＃中创建与.NET兼容的事件？

Question

我想从F＃类型发布事件，但我希望它被视为来自C＃或VB的事件。看来正确的方法是IEvent.create_HandlerEvent，但是这个函数并不存在于最新版本的F＃中。那么现在做什么是正确的方法呢？

Answer 1

事件是不是我的专长，但这个例子似乎在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
