Send a Brokered Message to Azure Service Bus

Log into the Azure portal and navigate to the Service Bus as outlined below.

Now create a namespace (for example testnamespace), a topic (for example testtopic) and a subscription (for example testsubscription1) and verify the configuration elements as in the following:

1. Base Address: "sb://testnamespace.servicebus.windows.net/"
2. Key Name: "RootManageSharedAccessKey"
3. Access Key: "zjoqxtDex7Bx3qXIXuedOiErinCOcnTPQ7aoEUhmelA="
4. Topic Name: "testtopic"

Step 3: Create Sender

The code excerpt to create a sender is outlined below. A token provider is created using key name and access key values. A Messaging Factory object is created by providing a token provider and baseaddress. The sender is created using a messaging factory object.

Also, please note that the token can be created with expiry duration passing TimeSpan input. Feel free to explore the TokenProviderClass in additional detail in MSDN.

Step 4: Build an Object to Send

For this step, let's consider a simple employeeobject with three fields (EmpId, EmpName and Date Of Hire) to show the process and populate the object with sample values as in the following.

1. namespace AzureServiceBus.Model
2. {
3. [DataContract]
4. public class Employee
5. {
6. [DataMember(Name = "empId")]
7. public string EmpId { get; set; }
8. [DataMember(Name = "empName")]
9. public string EmpName { get; set; }
10. [DataMember(Name = "dateOfHire")]
11. public DateTime DateOfHire { get; set; }
12. }
13. }
15. // Prepare message
16. Model.Employee employee = new Employee();
17. employee.EmpId = "1001";
18. employee.EmpName = "David";
19. employee.DateOfHire = new DateTime(1973, 8, 5);
    

Step 5: Send Message

Send a brokered message using the sender object, in which the brokered message body is filled with a custom object. Calling the send()method will drop your message on the Azure Service Bus and can be verified on a subscription.

1. // Send
2. sender.Send(new BrokeredMessage(employee));
3. Console.WriteLine("Message sent successfully.");
4. Console.ReadLine();
