Where can I find a simple example of creating a message to send?

SharpXMPP.XMPP.JID servjid = new SharpXMPP.XMPP.JID()
{
    User = user, Domain = server, Resource = Environment.MachineName
};

var xmppClient = new SharpXMPP.XmppClient(servjid, pass, false);

// Do I have to create the XML or is there methods to do it?
xmppClient.sxmppClient.Send(?????????);

xmppClient.sxmppClient.Send(new Message
                {
                    To = "[email protected]",
                    Text = "Hello!"
                });

Well, actually Message class is in wrong place: https://github.com/vitalyster/SharpXMPP/blob/master/SharpXMPP.WPF/Models/Message.cs - this should be moved to shared project

I used the nuget and only have the SharpXMPP.Shared. Do you plan to move to here?

Yes, but right now you can construct XMPPMessage to send the same way as it does in toXMPP method.

Hi, sry but..
Send method is failing, getting

Exception thrown: 'System.ArgumentNullException' in System.Xml.Linq.dll
System.ArgumentNullException: Value cannot be null.
Parameter name: writer
at System.Xml.Linq.XElement.WriteTo(XmlWriter writer)
at SharpXMPP.XmppTcpConnection.Send(XElement data)`

My code bellow

            var _xmppClient = new SharpXMPP.XmppClient(servjid, pass, false);

            XElement xmlSend = new XElement(
                "message",
                new XAttribute("from", servjid.FullJid),
                new XAttribute("to", tojid.FullJid),
                new XAttribute("type", "chat"),
                new XElement("body", message)
            );

            Log.Debug(xmlSend.ToString());
            /* returning: 
<message from="[email protected]/RUI-PC" to="[email protected]" type="chat">
  <body>Msg do c#</body>
</message>
             */

            var xmlXMsg = new XMPPMessage();
            xmlXMsg.SetAttributeValue(XNamespace.Get(Namespaces.JabberClient) + "type", "chat");
            xmlXMsg.SetAttributeValue(XNamespace.Get(Namespaces.JabberClient) + "id", servjid.FullJid);
            xmlXMsg.SetAttributeValue(XNamespace.Get(Namespaces.JabberClient) + "to", tojid.FullJid);
            var body = new XElement(XNamespace.Get(Namespaces.JabberClient) + "body");
            body.Value = message;
            xmlXMsg.Add(body);

            
            Log.Debug(xmlXMsg.ToString());
            /* returning: extra p1??
<message p1:type="chat" p1:id="[email protected]/RUI-PC" p1:to="[email protected]" xmlns:p1="jabber:client" xmlns="jabber:client">
  <p1:body>Msg do c#</p1:body>
</message>
 */

            _xmppClient.Send(xmlXMsg);
            /* Fatal Error:
Exception thrown: 'System.ArgumentNullException' in System.Xml.Linq.dll
System.ArgumentNullException: Value cannot be null.
Parameter name: writer
   at System.Xml.Linq.XElement.WriteTo(XmlWriter writer)
   at SharpXMPP.XmppTcpConnection.Send(XElement data)
            /*

Also strange is the XML using your method has a extra ´p1´ is that corect?

Thanks

I did a small code cleanup and do some tests and indeed, additional XML prefix was not correct. Now toXMPP method much simpler - https://github.com/vitalyster/SharpXMPP/blob/master/SharpXMPP.Shared/Messaging/Message.cs#L24

You can not send messages before you are signed in. Use SignedIn event handler to start messaging, check https://github.com/vitalyster/SharpXMPP/blob/master/SharpXMPP.Console/Program.cs
