public static System.ServiceModel.Channels.Message CreateMessage (System.Xml.XmlDictionaryReader envelopeReader, int maxSizeOfHeaders, System.ServiceModel.Channels.MessageVersion version);
static member CreateMessage : System.Xml.XmlDictionaryReader * int * System.ServiceModel.Channels.MessageVersion -> System.ServiceModel.Channels.Message
Public Shared Function CreateMessage (envelopeReader As XmlDictionaryReader, maxSizeOfHeaders As Integer, version As MessageVersion) As Message

Parameters

envelopeReader
XmlDictionaryReader

The XmlDictionaryReader object to be used for reading the SOAP message.

maxSizeOfHeaders
Int32

The maximum size in bytes of a header.

version
MessageVersion

A valid MessageVersion value that specifies the SOAP version to use for the message.

Returns

Message

A Message object for the message created.

Exceptions

ArgumentNullException

Remarks

Message takes ownership of envelopeReader.

This method reads the envelope, buffers all the headers into the header collection, and reads up to but not including the Body start tag, and returns the message. If the method call throws an exception, it closes the reader.
