Microsoft .Net Remoting系列专题之三：Remoting事件处理全接触

if (txtInfo.Text != string.Empty)

{

ServerForm.Obj.BroadCastingInfo(txtInfo.Text);

}

else

{

MessageBox.Show("请输入信息！");

}

但是很简单，就是调用远程对象的发送消息方法而已。

现在该实现客户端了。我们可以参照前面的例子，只是把服务端改为客户端而已。另外考虑到序列化安全级别的问题，所以代码会是这样：

private void ClientForm_Load(object sender, System.EventArgs e)

{

BinaryServerFormatterSinkProvider serverProvider = new

BinaryServerFormatterSinkProvider();

BinaryClientFormatterSinkProvider clientProvider = new

BinaryClientFormatterSinkProvider();

serverProvider.TypeFilterLevel = TypeFilterLevel.Full;

IDictionary props = new Hashtable();

props["port"] = 0;

HttpChannel channel = new HttpChannel(props,clientProvider,serverProvider);

ChannelServices.RegisterChannel(channel);

watch = (IBroadCast)Activator.GetObject(

typeof(IBroadCast),"http://localhost:8080/BroadCastMessage.soap");

watch.BroadCastEvent += new BroadCastEventHandler(BroadCastingMessage);

}

注意客户端通道的端口号应设置为0，这表示客户端自动选择可用的端口号。如果要设置为指定的端口号，则必须保证与服务端通道的端口号不相同。

然后是，BroadCastEventHandler委托的方法：

public void BroadCastingMessage(string message)

{

txtMessage.Text += "I got it:" + message;

txtMessage.Text += System.Environment.NewLine;

}

客户端界面如图：
