vs2008 c＃：为facebook winform应用程序添加事件到事件列表控件

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？以下代码无效

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


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

错误消息

错误1无法将类型'System.Collections.Generic.IList'隐式转换为'System.Collections.ObjectModel.Collection'。存在显式转换（您是否缺少转换？）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）吗？

    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);
    }
