StackExchange.Redis Publish Subscribe Complex Data (JSON)

Example

You can broadcast more complex messages by serializing the payload before you publish it:

// definition of a message
public class ChatMessage
{
    public Guid Id { get; set; }
    public string User { get; set; }
    public string Text { get; set; }
}

// grab an instance of an ISubscriber
var subscriber = connection.GetSubscriber();

var message = new ChatMessage
{
    Id = Guid.NewGuid(), 
    User = "User 1234", 
    Text = "Hello World!"
};

// serialize a ChatMessage
// this uses JIL to serialize to JSON
var json = JSON.Serialize(message);

// publish the message to the 'chat' channel
subscriber.Publish("chat", json)

The subscriber then needs to deserialize the message:

// grab an instance of an ISubscriber
var subscriber = connection.GetSubscriber();

// subscribe to messages over the 'chat' channel
subscriber.Subscribe("chat", (channel, json) => {
    var message = JSON.Deserialize<ChatMessage>(json);

    // do something with the message
    Console.WriteLine($"{message.User} said {message.Text}");
});
