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)


public class ActionMessageFilter : MessageFilter


Initializes a new instance of this class with the set of actions for which it tests.


Gets a read-only copy of action strings for which this ActionMessageFilter tests.


Creates a new filter table that tests efficiently on message actions.(Overrides MessageFilter.CreateFilterTable<FilterData>().)


Determines whether the specified object is equal to the current object.(Inherited from Object.)


Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)


Serves as the default hash function. (Inherited from Object.)


Gets the Type of the current instance.(Inherited from Object.)


Tests whether a message's action matches one of the actions specified in this ActionMessageFilter.(Overrides MessageFilter.Match(Message).)


Tests whether a buffered message's action header matches one of the actions specified in this ActionMessageFilter.(Overrides MessageFilter.Match(MessageBuffer).)


Creates a shallow copy of the current Object.(Inherited from Object.)


Returns a string that represents the current object.(Inherited from Object.)

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.

    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)

            // 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);
