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

'Declaration
<DataContractAttribute> _
Public Class ActionMessageFilter _
	Inherits MessageFilter
'Usage
Dim instance As ActionMessageFilter

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.

            Dim myActFltr As ActionMessageFilter = New ActionMessageFilter("1st Action", "2nd Action")
            Dim yourACtFltr As ActionMessageFilter = New ActionMessageFilter("Your Action")

            ' Display the ActionMessageFilter actions.
