应该限制 TEventArgs 是参数也就是加上 where TEventArgs 是具体的什么
| { | ||
| public class EventInfomation<TEventArgs> | ||
| { | ||
| public object Sender { get; set; } |
|
|
||
| namespace lindexi.MVVM.Framework.ViewModel | ||
| { | ||
| public abstract class MapEventToCommandBase<TEventArgs>:TriggerAction<DependencyObject> where TEventArgs:EventArgs |
|
|
||
| protected override void Invoke(object parameter) | ||
| { | ||
| if (base.AssociatedObject!=null) |
| EventInfomation<TEventArgs> eventInfomation = new EventInfomation<TEventArgs>() | ||
| { | ||
| Sender=base.AssociatedObject, | ||

这里有要求 parameter 一定就是 TEventArgs 不让就应该给异常
| } | ||
| return command; | ||
| } | ||
|
|
| public Action<object> ViewModelAction | ||
| { | ||
| get { return _viewModelAction; } | ||
| set { _viewModelAction = value; } |
