- TChannel
聽眾能接受的頻道類型。
參數
- context
- BindingContext
BindingContext那就為綁定元素提供了背景。
傳回
由 初始化的 IChannelListener<TChannel>型別IChannel。context
例外狀況
context 是 null。
範例
CustomBinding binding = new CustomBinding();
HttpTransportBindingElement element = new HttpTransportBindingElement();
BindingParameterCollection parameters = new BindingParameterCollection();
Uri baseAddress = new Uri("http://localhost:8000/ChannelApp");
String relAddress = "http://localhost:8000/ChannelApp/service";
BindingContext context = new BindingContext(binding, parameters, baseAddress, relAddress, ListenUriMode.Explicit);
IChannelListener<IReplyChannel> listener = element.BuildChannelListener<IReplyChannel>(context);
listener.Open();
IReplyChannel channel = listener.AcceptChannel();
channel.Open();
RequestContext request = channel.ReceiveRequest();
Message msg = request.RequestMessage;
Console.WriteLine("Message Received");
Console.WriteLine("Message Action: {0}", msg.Headers.Action);
if (msg.Headers.Action == "hello")
{
Message reply = Message.CreateMessage(MessageVersion.Default, "wcf");
request.Reply(reply);
}
msg.Close();
channel.Close();
listener.Close();
