有两种通道来使用最新的网络通讯组件Indigo:typeed 和untyped,typed channel是通过Server端的WSDL,即通过自动自动生成的interface,很明显，我们要遵守一个契约。另一个方面，我们可以使用untyped channel,在这个通道里，我们只是从一端到另一端传递最基本的Message(Indigo中的最基本单元)，没有协议需要遵守，通常基于一个action URI.
看一个sample:

using System;<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

using System.MessageBus;

The client:

class Client

{

[STAThread]

static void <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Main(string[] args)

{

Uri client = new Uri(String.Format("soap.tcp://{0}:6000/Client", System.Environment.MachineName));

Uri server = new Uri(String.Format("soap.tcp://{0}:6001/Server", System.Environment.MachineName));

Console.WriteLine("Client - {0}", client.ToString());

Uri action = new Uri("http://tempuri.org/action1");

Message message = new Message(action, "Hello");

message.Headers.Add(new PathHeader(server));

message.Headers.Add(new ToHeader(server));

message.Headers.Add(new ReplyInfoHeader(client));

Port port = new Port(client);

port.Open();

port.SendChannel.Send(message);

port.Close();

}

}

The Server:

class Server

{

[STAThread]

static void Main(string[] args)

{

Uri server = new Uri(String.Format("soap.tcp://{0}:6001/Server", System.Environment.MachineName));

Port port = new Port(server);

ServerMessageHandler handler = new ServerMessageHandler();

port.ReceiveChannel.Handler = handler;

port.CloseTimeout = new TimeSpan(1, 0, 0, 0);

port.Open();

Console.WriteLine("Server - {0}", server.ToString());

Console.ReadLine();

}

}

public class ServerMessageHandler : SyncMessageHandler

{

public override bool ProcessMessage(Message message)

{

string content = message.Content.GetObject(typeof(string)) as string;

Console.WriteLine(content);

Console.ReadLine();

return true;

}

}
看上去和remoting有点类似，其实编程方式更加简洁，更好理解。
