Writes the entire content of this buffer to the specified IO stream.

public:
 virtual void WriteMessage(System::IO::Stream ^ stream);

public virtual void WriteMessage (System.IO.Stream stream);

abstract member WriteMessage : System.IO.Stream -> unit
override this.WriteMessage : System.IO.Stream -> unit

Public Overridable Sub WriteMessage (stream As Stream)

Parameters

stream: Stream

An IO stream that the entire content of this buffer is written to.

Examples

private byte[] ConvertMessageToByteArray(ref Message message)   
{  
    // Memory stream that contains the message.
    var stream = new MemoryStream();  
    // Create an XmlWriter to serialize the message into a byte array.
    var settings = new XmlWriterSettings();
    settings.Encoding = System.Text.Encoding.UTF8;
    XmlWriter writer = XmlWriter.Create(stream, settings);
    // Copy the message into a buffer.
    // Note: This call changes the original message's state.
    MessageBuffer buffer = message.CreateBufferedCopy(int.MaxValue);  
    // Create a copy of the message.
    message = buffer.CreateMessage();  
    // Serialize the message to the XmlWriter.
    message.WriteMessage(writer);  
    // Recreate the message.
    message = buffer.CreateMessage();
    // Flush the contents of the writer so that the stream gets updated.
    writer.Flush();  
    stream.Flush();  
    // Convert the stream to an array.
    byte[] retval = stream.ToArray();
    return retval;
}

Remarks

This function uses a binary encoder instead of a UTF-8 encoder. Therefore, you cannot directly convert from a MessageBuffer to a Message. The code in the example section shows how to work around this problem.
