vs2008 c＃：将事件添加到facebook的winform应用程序的eventlist控件

Question

这是一个桌面应用程序。如何将事件添加到事件列表控件？下面的代码是不工作

IList<user> friends = facebookService1.Friends.GetUserObjects(); 
    IList<facebookevent> events = facebookService1.Events.Get(); 


    friendList1.Friends = friends; 
    eventList1.FacebookEvents = events; 

错误信息

错误1无法隐式转换类型“System.Collections.Generic.IList”到“System.Collections.ObjectModel.Collection”。 C：\ Documents and Settings \ ZULFIQAR SYED \ Local Settings \ Application Data \ Temporary Projects \ WindowsFormsApplication1 \ Form1.cs 42 41 WindowsFormsApplication1

Answer 1

您的意思是受保护的Events成员（EventHandlerList）？

private static readonly object MyEventKey = new object(); 
    public event EventHandler MyEvent 
    { 
     add {Events.AddHandler(MyEventKey, value);} 
     remove {Events.RemoveHandler(MyEventKey, value);} 
    } 
    protected virtual void OnMyEvent() 
    { 
     EventHandler handler = (EventHandler)Events[MyEventKey]; 
     if (handler != null) handler(this, EventArgs.Empty); 
    }
