近日在使用企业库中的CAB的EventBroker对
LightweightCTI进行改造时碰到了一个另人预想不到的问题，我在其中一个Module中发布的事件通过其它的Module中出现无法接受此事件的情况。
事件发布的代码如下：
事件发布代码段
1 Channel Common Events#region Channel Common Events
2
3 [EventPublication(SwitchEventNames.ChannelStatusChangedEvent, PublicationScope.Global)]
4 public event EventHandler<EventArgs<ChannelStatus>> ChannelStatusChanged;
5 protected virtual void OnChannelStatusChanged(object sender, EventArgs<ChannelStatus> e)
6
{
7 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.ChannelStatusChanged))
8 {
9 RunScripts(ChannelEventHandlerName.ChannelStatusChanged);
10
}
11 else
12 if (this.ChannelStatusChanged != null)
13 {
14 this.ChannelStatusChanged(sender, e);
15 }
16 }
17
18 [EventPublication(SwitchEventNames.GetDTMFEvent, PublicationScope.Global)]
19 public event EventHandler<EventArgs<string>> GetDTMF;
20 protected virtual void OnGetDTMF(object sender, EventArgs<string> e)
21 {
22 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.GetDTMF))
23 {
24 RunScripts(ChannelEventHandlerName.GetDTMF);
25 }
26 else
27 if (this.GetDTMF != null)
28 {
29 this.GetDTMF(sender, e);
30 }
31 }

33 [EventPublication(SwitchEventNames.CallEvent, PublicationScope.Global)]
34 public event EventHandler<CallEventArgs> Call;
35 protected virtual void OnCall(object sender, CallEventArgs e)
36 {
37 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.Call))
38 {
39 RunScripts(ChannelEventHandlerName.Call);
40 }
41 else
42 if (this.Call != null)
43 {
44 this.Call(sender, e);
45 }
46 }

48 [EventPublication(SwitchEventNames.FaxingEvent, PublicationScope.Global)]
49 public event EventHandler<FaxEventArgs> Faxing;
50 protected virtual void OnFaxing(object sender, FaxEventArgs e)
51 {
52 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.Faxing))
53 {

64 {
65 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.LinkingToChannel))
66 {
67 RunScripts(ChannelEventHandlerName.LinkingToChannel);
68 }
69 else
70 if (this.LinkingToChannel != null)
71 {
72 this.LinkingToChannel(sender, e);
73 }
74 }
75
76 [EventPublication(SwitchEventNames.LinkedToChannelEvent, PublicationScope.Global)]
77 public event EventHandler<EventArgs<IChannel>> LinkedToChannel;
78 protected virtual void OnLinkedToChannel(object sender, EventArgs<IChannel> e)
79 {
80 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.LinkedToChannel))
81 {
82 RunScripts(ChannelEventHandlerName.LinkedToChannel);
83 }
84 else
85 if (this.LinkedToChannel != null)
86 {
87 this.LinkedToChannel(sender, e);
88 }
89 }
90
91 [EventPublication(SwitchEventNames.ResetedChannelEvent, PublicationScope.Global)]
92 public event EventHandler ResetedChannel;
93 protected virtual void OnResetedChannel(object sender, EventArgs e)
94 {
95 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.ResetedChannel))
96 {
97 RunScripts(ChannelEventHandlerName.ResetedChannel);
98 }
99 else
100 if (this.ResetedChannel != null)
101 {

103 }
104 }
105
106 [EventPublication(SwitchEventNames.ProcessTimeoutEvent, PublicationScope.Global)]
107 public event EventHandler ProcessTimeout;
108 protected virtual void OnProcessTimeout(object sender, EventArgs e)
109 {
110 if (scriptLoaders.ContainsKey(ChannelEventHandlerName.ProcessTimeout))
111 {
112 RunScripts(ChannelEventHandlerName.ProcessTimeout);
113 }
114 else
115 if (this.ProcessTimeout != null)
116 {
117 this.ProcessTimeout(sender, e);
118 }
119 }

#endregion 在另外一个Module中的一个SmartPart View进行事件订阅的代码段如下：
事件订阅代码
1
[EventSubscription(SwitchEventNames.ChannelStatusChangedEvent, ThreadOption.UserInterface)]
2 public void ChannelStatusChangedHandler(object sender, EventArgs<ChannelStatus> e)
3 {
4 IChannel chnl = (IChannel)sender;
5 ChannelsView.Items[chnl.ChannelID].SubItems[1].Text = Enum.GetName(typeof(ChannelStatus), e.Data);
6 }
7 其中，事件发布的对象是由类工厂进行创建的，类工厂的事件却可以成功订阅。几经查询终无所获，希望对MS企业库熟悉的朋友帮忙看一下，是否我在进行事件发布与订阅时有什么地方还没有需要注意一下，在此先行谢过各位啦。
