F#:使用INotifyPropertyChanged进行数据绑定

Question

如何实现INotifyPropertyChanged以用于F#类型？谢谢!

Answer 1

它与任何其他语言基本相同:

open System.ComponentModel
type MyType() =
  let ev = new Event<_,_>()
  let mutable str = ""
  member x.StringProp
    with get() = str
     and set(str') =
       str <- str'
       ev.Trigger(x, PropertyChangedEventArgs("StringProp"))
  interface INotifyPropertyChanged with
    [<CLIEvent>]
    member x.PropertyChanged = ev.Publish
