Getting OperationContract name in WCF MessageDispatcher

There may be times where you need to identify the OperationContract name in WCF MessageDispatcher and do some processing based on that. Here is how you can do that;

In case of WCF Endpoint

In the AfterReceiveRequest method, do the following to get the Operation name;

MessageBuffer buffer = request.CreateBufferedCopy(Int32.MaxValue);

Message originalMessage = buffer.CreateMessage();

XmlDictionaryReader xmlDict = orginialMessage.GetReaderAtBodyContents();

XmlDocument doc = new XmlDocument();

doc.LoadXml(xmlDict.ReadOuterXml());

string action = doc.DocumentElement.Name; //here you will get the OperationContract name

In case of WCF REST Endpoint

In the AfterReceiveRequest method, do the following to get the Operation name;

MessageProperties props = request.Properties;
string action = props["HttpOperationName"].ToString(); //here you will get the OperationContract name
