MessageFilterTable<TFilterData>.GetMatchingFilters Method (MessageBuffer, ICollection<MessageFilter>)

Returns a value that indicates whether the match criterion of at least one filter in the table is satisfied by the specified buffered message and adds the matching filters from the highest priority set of filters in which at least one match is found to a collection.

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

public bool GetMatchingFilters(
	MessageBuffer buffer,
	ICollection<MessageFilter> results
)

Parameters

buffer
Type: System.ServiceModel.Channels.MessageBuffer
The MessageBuffer to test.
results
Type: System.Collections.Generic.ICollection<MessageFilter>
The reference parameter that stores the MessageFilter objects that match in ICollection<T><Filter>.

Return Value

Implements

IMessageFilterTable<TFilterData>.GetMatchingFilters(MessageBuffer, ICollection<MessageFilter>)

ExceptionCondition
ArgumentNullException

results is null.

Use this method when more than one filter is expected to match the buffered message and the matching filters are required.

The filters in the table are allowed to inspect the message body.

The matching MessageFilter objects are stored in the results parameter of ICollection<T>. The FilterData can then be recovered from the filter table using these filters as keys with the methods provided by IDictionary<TKey, TValue>.

This method implements GetMatchingFilters.
