## MqttClient Please find examples and the documentation at the Wiki of this repository (https://github.com/chkr1011/MQTTnet/wiki).
```csharp
var options = new MqttClientOptions
{
Server = "localhost"
};
var client = new MqttClientFactory().CreateMqttClient(options);
client.ApplicationMessageReceived += (s, e) =>
{
Console.WriteLine("### RECEIVED APPLICATION MESSAGE ###");

Console.WriteLine($"+ Payload = {Encoding.UTF8.GetString(e.ApplicationMessage.Payload)}");
Console.WriteLine($"+ QoS = {e.ApplicationMessage.QualityOfServiceLevel}");
Console.WriteLine($"+ Retain = {e.ApplicationMessage.Retain}");
Console.WriteLine();
};
client.Connected += async (s, e) =>
{
Console.WriteLine("### CONNECTED WITH SERVER, SUBSCRIBING ###");
await client.SubscribeAsync(new List<TopicFilter>
{
new TopicFilter("#", MqttQualityOfServiceLevel.AtMostOnce)
});
};
client.Disconnected += async (s, e) =>
{
Console.WriteLine("### DISCONNECTED FROM SERVER ###");
await Task.Delay(TimeSpan.FromSeconds(5));
try
{
await client.ConnectAsync();
}
catch
{
Console.WriteLine("### RECONNECTING FAILED ###");
}
};
try
{
await client.ConnectAsync();
}
catch
{
Console.WriteLine("### CONNECTING FAILED ###");
}
Console.WriteLine("### WAITING FOR APPLICATION MESSAGES ###");
var messageFactory = new MqttApplicationMessageFactory();
while (true)
{
Console.ReadLine();
var applicationMessage = messageFactory.CreateApplicationMessage("myTopic", "Hello World", MqttQualityOfServiceLevel.AtLeastOnce);
await client.PublishAsync(applicationMessage);
}
```
## MqttServer
```csharp
var options = new MqttServerOptions
{
ConnectionValidator = p =>
{
if (p.ClientId == "SpecialClient")
{
if (p.Username != "USER" || p.Password != "PASS")
{
return MqttConnectReturnCode.ConnectionRefusedBadUsernameOrPassword;
}
}
return MqttConnectReturnCode.ConnectionAccepted;
}
};
var mqttServer = new MqttServerFactory().CreateMqttServer(options);
mqttServer.Start();
Console.WriteLine("Press any key to exit.");
Console.ReadLine();
mqttServer.Stop();
```
