MessageFilter.Match Method (MessageBuffer)
When overridden in a derived class, tests whether a buffered message satisfies the criteria of a filter.
Assembly: System.ServiceModel (in System.ServiceModel.dll)
The message must be fully buffered if the body is to be inspected by the filter. The body of the MessageBuffer is fully buffered and therefore can be inspected by a filter. The body of a Message that has not been fully buffered may be consumed by the filter inspection. The header element of a Message is automatically buffered and therefore can be inspected without being consumed.
