public class ConnectionStringBuilder

This class can be used to construct a connection string which can establish communication with ServiceBus entities. It can also be used to perform basic validation on an existing connection string.

Sample Code:

ConnectionStringBuilder connectionStringBuilder = new ConnectionStringBuilder(
                                          "ServiceBusNamespaceName", 
                                          "ServiceBusEntityName", // QueueName or TopicName or SubscriptionPath
                                          "SharedAccessSignatureKeyName", 
                                          "SharedAccessSignatureKey");
  
 String connectionString = connectionStringBuilder.toString();

A connection string is basically a string consisted of key-value pair separated by ";". Basic format is {=[;=]} where supported key name are as follow:

  • Endpoint - URL that points to the servicebus namespace
  • EntityPath - Path to the service bus entity (queue/topic/subscription/). For queues and topics, it is just the entity name. For subscriptions, path is /subscriptions/
  • SharedAccessKeyName - Key name to the corresponding shared access policy rule for the namespace, or entity.
  • SharedAccessKey - Key value for the corresponding shared access policy rule of the namespace or entity.
  • SharedAccessSignatureToken - Instead of a key name and key value, clients can provide an already generated SAS Token.
  • OperationTimeout - Default timeout to be used for all senders, receiver and clients created from this connection string.
  • RetryPolicy - Name of the retry policy.
