![]() | ToLookup<MessageHeaderInfo, TKey, TElement>(Func<MessageHeaderInfo, TKey>, Func<MessageHeaderInfo, TElement>) | Overloaded. Creates a Lookup<TKey, TElement> from an IEnumerable<T> according to specified key selector and element selector functions.(Defined by Enumerable.) |
![]() | ToLookup<MessageHeaderInfo, TKey, TElement>(Func<MessageHeaderInfo, TKey>, Func<MessageHeaderInfo, TElement>, IEqualityComparer<TKey>) | Overloaded. Creates a Lookup<TKey, TElement> from an IEnumerable<T> according to a specified key selector function, a comparer and an element selector function.(Defined by Enumerable.) |
![]() | Union<MessageHeaderInfo>(IEnumerable<MessageHeaderInfo>) | Overloaded. Produces the set union of two sequences by using the default equality comparer.(Defined by Enumerable.) |
![]() | Union<MessageHeaderInfo>(IEnumerable<MessageHeaderInfo>, IEqualityComparer<MessageHeaderInfo>) | Overloaded. Produces the set union of two sequences by using a specified IEqualityComparer<T>.(Defined by Enumerable.) |
![]() | Where<MessageHeaderInfo>(Func<MessageHeaderInfo, Boolean>) | Overloaded. Filters a sequence of values based on a predicate.(Defined by Enumerable.) |
![]() | Where<MessageHeaderInfo>(Func<MessageHeaderInfo, Int32, Boolean>) | Overloaded. Filters a sequence of values based on a predicate. Each element's index is used in the logic of the predicate function.(Defined by Enumerable.) |
![]() | Zip<MessageHeaderInfo, TSecond, TResult>(IEnumerable<TSecond>, Func<MessageHeaderInfo, TSecond, TResult>) | Applies a specified function to the corresponding elements of two sequences, producing a sequence of the results.(Defined by Enumerable.) |
A message header contains optional metadata that describe a message encapsulated by the Message class.
A Message can have zero or more headers that are used as an extension mechanism to pass information in messages that are application-specific. You can use Headers to add message headers to a message by calling the Add method.
Windows Communication Foundation (WCF) provides a number of predefined message headers:
Header Name | Description |
|---|---|
To | Contains the role that the message is targeting. |
Action | Provides a description of how the message should be processed. |
FaultTo | Contains the address of the node to which faults should be sent. |
From | Contains the address of the node that sent the message. |
Request | Indicates whether the message is a request. |
MessageID | Contains the unique ID of the message. |
RelatesTo | Contains the IDs of messages that are related to this message. |
ReplyTo | Contains the address of the node to which a reply should be sent for a request. |
The following code example demonstrates a basic client using the channel factory to send a message and read the action header from the reply.
using System; using System.Collections.Generic; using System.Text; using System.ServiceModel; using System.ServiceModel.Channels; using System.Runtime.Serialization; namespace ConsoleApplication1 { class client { static void RunClient() { //Step1: create a binding with just HTTP CustomBinding binding = new CustomBinding(); binding.Elements.Add(new HttpTransportBindingElement()); //Step2: use the binding to build the channel factory IChannelFactory<IRequestChannel> factory = binding.BuildChannelFactory<IRequestChannel>( new BindingParameterCollection()); //open the channel factory factory.Open(); //Step3: use the channel factory to create a channel IRequestChannel channel = factory.CreateChannel( new EndpointAddress("http://localhost:8080/channelapp")); channel.Open(); //Step4: create a message Message requestmessage = Message.CreateMessage( MessageVersion.Soap12WSAddressing10, "http://contoso.com/someaction", "This is the body data"); //send message Message replymessage = channel.Request(requestmessage); Console.WriteLine("Reply message received"); Console.WriteLine("Reply action: {0}", replymessage.Headers.Action); string data = replymessage.GetBody<string>(); Console.WriteLine("Reply content: {0}", data); //Step5: don't forget to close the message requestmessage.Close(); replymessage.Close(); //don't forget to close the channel channel.Close(); //don't forget to close the factory factory.Close(); } public static void Main() { Console.WriteLine("Press [ENTER] when service is ready"); Console.ReadLine(); RunClient(); Console.WriteLine("Press [ENTER] to exit"); Console.ReadLine(); } } }
