ActionMessageFilter Class

Represents a query that tests whether the action of a message is one of a specified set of actions.

Namespace:  System.ServiceModel.Dispatcher
Assembly:  System.ServiceModel (in System.ServiceModel.dll)

[DataContractAttribute]
public class ActionMessageFilter : MessageFilter

It is invalid to construct an ActionMessageFilter with no actions.

This type is serializable as a DataContractAttribute.

The following example creates two ActionMessageFilters, gets the action string out of one of the filters using the Actions property, tests a message against the action filters directly, and displays the result of applying the filter.

using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Dispatcher;

namespace UE.Wfc.Samples
{
    public static class ActionMessageFilterMatching
    {
        public static void Main()
        {
            // Create several action filters.
            ActionMessageFilter myActFltr = new ActionMessageFilter("1st Action", "2nd Action");
            ActionMessageFilter yourActFltr = new ActionMessageFilter("Your Action");

            // Display the ActionMessageFilter actions.
            ReadOnlyCollection<string> results = myActFltr.Actions;

            foreach (string result in results)
            {
                System.Console.WriteLine(result);
            }

            // Create a message.
            Message message = Message.CreateMessage(MessageVersion.Soap12WSAddressing10, "myBody");

            // Test the message action against a single action filter. 
            bool test1 = myActFltr.Match(message);
            bool test2 = yourActFltr.Match(message);
            System.Console.WriteLine("The result of test1 is {0}", test1);
            System.Console.WriteLine("The result of test2 is {0}", test2);
        }
    }
}
