![]() ![]() Now open Program.cs class file and write a code in the Main method to call Fanoutmessages.cs class to get messages from rabbitmq. After that, we are publishing a message ( Message is of fanout Exchange type) to the queue by passing required parameters like an exchange, routing key, properties, and message to the BasicPublish method. ![]() If you observe the above code, to establish a connection with rabbitmq server we are passing the required credentials along with the HostName to ConnectionFactory() method. Model.BasicPublish("fanout.exchange", "", properties, messagebuffer) Ĭonsole.WriteLine("Message Sent From : fanout.exchange") Ĭonsole.WriteLine("Routing Key : Routing key is not required for fanout exchange") Var properties = model.CreateBasicProperties() īyte messagebuffer = ("Message is of fanout Exchange type") Var connection = connectionFactory.CreateConnection() Var connectionFactory = new ConnectionFactory() Private const string HName = "localhost" Now, open the Fanoutmessages.cs class file and write the code as shown below. To publish messages to the rabbitmq queue, add a class with the name “ Fanoutmessages.cs” in your application as shown below. Same way, bind the remaining queues ( Chennai, Hyderabad, Mumbai) also to an exchange ( fanout.exchange) in rabbitmq web admin console.Īfter the completion of binding queues ( Bangalore, Chennai, Hyderabad, Mumbai) to an exchange ( fanout.exchange), now we will publish messages from the c# application to rabbitmq queues using RabbitMQ.Client service. To bind a queue with an exchange, click on the queue ( Bangalore) name, then the Bindings panel will expand and enter details like exchange name as “ fanout.exchange” and click on the Bind button as shown below.Īfter binding a queue ( Bangalore) to exchange ( fanout.exchange), the binding will be as shown below. Similar way, add the remaining three queues ( Bangalore, Chennai, Hyderabad) in rabbitmq as shown below.Īfter adding all the queues, next we will bind all the queues to “ fanout.exchange” in rabbitmq web admin console. To create a queue in rabbitmq web management portal, open and then go to Add a new queue panel and enter details as shown below, and click on Add queue button to create a queue ( Mumbai). ![]() To create an exchange in rabbitmq web management portal, open and then go to Add a new exchange panel and enter details as shown below by selecting Type as “ fanout” and click on Add exchange button to create an exchange ( fanout.exchange).Īfter creating an exchange ( fanout.exchange), next, we will create 4 queues (Mumbai, Hyderabad, Bangalore, and Chennai) and bind them to the same exchange ( fanout.exchange) in the web management portal. Now search for RabbitMQ.Client package and install it in your application as shown below.įollowing is another way to install RabbitMQ.Client package by using Package Manager Console as shown below by entering the following command.Ĭommand to install - Install-Package RabbitMQ.Client -Version 5.1.0īefore we start writing a code in c# to publish messages to rabbitmq, we will create a fanout exchange, queue and will bind a queue to exchange using the web admin console. In c#, we can publish or consume messages from rabbitmq by using RabbitMQ.Client NuGet package for that, right-click on your application and select Manage NuGet Packages as shown below. Let’s create a simple console application with the Name “ RequestRabbitMQ” as shown below to publish messages to the rabbitmq queue using fanout exchange in c#.Īfter creating an application, now we will add the “ RabbitMQ.Client” NuGet package in our c# application to communicate with rabbitmq server to publish or consume messages from queues in rabbitmq. Now, we will learn how to use Fanout Exchange to push and read messages from rabbitmq in c# or. To know more about exchanges in rabbitmq, check this RabbitMQ Exchanges.įollowing is the pictorial representation of message flow in the rabbit fanout exchange. In rabbitmq, we have different types of exchanges available are Generally, in rabbitmq when the producer creates a message that will not directly send to the queue, instead first the message will be sent to exchanges, then after that, a routing agent reads and sends it to the appropriate queue with help of header attributes, bindings and routing keys. The fanout exchange is useful when we want to publish a common message to all the queues that are bound with a particular exchange and in the fanout exchange, the routing key is ignored.įor example, if the company has updated some guidelines and you want to push those guidelines to all the branches that time you can use fanout exchange. In rabbitmq, Fanout Exchange will route messages to all of the queues that are bound to it. ![]()
