MatriX XMPP - Connect and send message

Connect and send message

This basic example shows how to connect to a server and send a siple chat message to another user. The steps required are the following:

Create XmppClient and set username, password and XMPP domain properties
call connect to create the connection, authenticate etc…
Rquest the contact list from the server (optional)
Send our own presence to the server
Send a chat message from the logged in user1 to user2 on the same server which is example.com

Example

// setup XmppClient with some properties
var xmppClient = new XmppClient
{
    Username = "user1",
    Password = "secret",
    XmppDomain = "example.com",
    // setting the resolver to use the Srv resolver is optional, but recommended
    HostnameResolver = new SrvNameResolver()   
};

// connect so the server
await xmppClient.ConnectAsync();
 
// request roster (contact list). This is optional, 
// but most chat clients do this on startup
var roster = await xmppClient.RequestRosterAsync();
 
// send our own presence to the server. This is required for most scenarios
// but there are also use cases where you may not want to publish and send you own presence
await xmppClient.SendPresenceAsync(Show.Chat, "free for Chat");

// send a chat message to user2
await xmppClient.SendChatMessageAsync("user2@exmaple.com", "This is a test");

// Close connection again
await xmppClient.DisconnectAsync();
