只要使用到两个类一个用来发送一个用来接收。
可以有多个发送端，但只能有一个接收端。
来段demo
public partial class localcoon : UserControl {
public localcoon() {
InitializeComponent();
//
_sender = new LocalMessageSender("InAction", LocalMessageSender.Global);
textBox1.TextChanged += (s, e) => {
{
_sender.SendAsync(textBox1.Text);
}
};
}
private LocalMessageSender _sender;
private void button1_Click(object sender, RoutedEventArgs e1) {
//表示两个基于 Silverlight 的应用程序之间的本地消息传递通道的接收端。
LocalMessageReceiver _receive;
_receive = new LocalMessageReceiver("InAction",
ReceiverNameScope.Global, LocalMessageReceiver.AnyDomain);
_receive.Listen();
_receive.MessageReceived += (s, e) => {
textBlock3.Text =
"Message: " + e.Message + Environment.NewLine +
"NameScope " + e.NameScope +
" completed." + Environment.NewLine +
"Response: " + e.Response + Environment.NewLine +
"ReceiverName: " + e.ReceiverName + Environment.NewLine +
//获取此发送方会将消息发送到的 LocalMessageReceiver 的名称。
"SenderDomain: " + e.SenderDomain;//获取此发送方会将消息发送到的 LocalMessageReceiver 的域
};
}
}
public localcoon() {
InitializeComponent();
//
_sender = new LocalMessageSender("InAction", LocalMessageSender.Global);
textBox1.TextChanged += (s, e) => {
{
_sender.SendAsync(textBox1.Text);
}
};
}
private LocalMessageSender _sender;
private void button1_Click(object sender, RoutedEventArgs e1) {
//表示两个基于 Silverlight 的应用程序之间的本地消息传递通道的接收端。
LocalMessageReceiver _receive;
_receive = new LocalMessageReceiver("InAction",
ReceiverNameScope.Global, LocalMessageReceiver.AnyDomain);
_receive.Listen();
_receive.MessageReceived += (s, e) => {
textBlock3.Text =
"Message: " + e.Message + Environment.NewLine +
"NameScope " + e.NameScope +
" completed." + Environment.NewLine +
"Response: " + e.Response + Environment.NewLine +
"ReceiverName: " + e.ReceiverName + Environment.NewLine +
//获取此发送方会将消息发送到的 LocalMessageReceiver 的名称。
"SenderDomain: " + e.SenderDomain;//获取此发送方会将消息发送到的 LocalMessageReceiver 的域
};
}
}
其中一个是IE9 一个是 opera浏览器。
一些模糊的概念
1域
详见扩展阅读
“域（Domain）”和“应用程序域（AppDomain）”不是一回事。域表明了Silverlight应用程序的位置信息，诸如：“www.myuniversity.edu.cn”之类，而应用程序域则代表了Silverlight应用程序的运行环境，Silverlight插件在装载一个Silverlight应用程序时，会为其创建一个应用程序域作为其运行环境。
假设某网页使用多个<object>元素承载了多个Silverlight应用程序，则Silverlight插件会为每个Silverlight应用程序创建相互独立的应用程序域，这些Silverlight应用程序的“域”可以相同（只要来源于同一个网站），也可以不同（如果来源于不同的网站）

自定义的时候可以是
Receiver = new LocalMessageReceiver("InAction",
ReceiverNameScope.Global,
new string[] {"www.baidu.com",www.xxx.com});
如果想指定任意可以是*
4其最终是调用下面函数发送的
[DllImport("agcore", EntryPoint="LocalMessageSend")]
private static extern uint LocalMessageSendNative
(IntPtr nativePeerPtr, uint cMessage, [MarshalAs(UnmanagedType.LPWStr)] string message,
uint cReceiverName, [MarshalAs(UnmanagedType.LPWStr)] string receiverName,
uint cReceiverDomain, [MarshalAs(UnmanagedType.LPWStr)] string receiverDomain, uint managedKey);
应用
本地程序通讯可以用于，只启动一个程序或者，同一个浏览器中多个关联Silverlight程序之间的信息共享。
