IAsyncResult實(shí)現(xiàn)

異步返回處理對(duì)象實(shí)現(xiàn)也很簡(jiǎn)單,實(shí)現(xiàn)一個(gè)Execute方法由隊(duì)列執(zhí)行,執(zhí)行完成后通過(guò)callBack方法來(lái)通知處理完成.

public class AspxAsyncResult : IAsyncResult

        bool m_IsCompleted = false;

        {
            mHandler = handler;

            m_Callback = cb;
        }
