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.

Constructor Details

ConnectionStringBuilder

public ConnectionStringBuilder(String connectionString)

Creates a new instance from the given connection string. ConnectionString format: Endpoint=sb://namespace_DNS_Name;EntityPath=EVENT_HUB_NAME;SharedAccessKeyName=SHARED_ACCESS_KEY_NAME;SharedAccessKey=SHARED_ACCESS_KEY or Endpoint=sb://namespace_DNS_Name;EntityPath=EVENT_HUB_NAME;SharedAccessSignatureToken=SHARED_ACCESS_SIGNATURE_TOKEN

Parameters:

connectionString - ServiceBus ConnectionString

ConnectionStringBuilder

public ConnectionStringBuilder(String namespaceConnectionString, String entityPath)

Creates a new instance from the given connection string and entity path. A connection string may or may not include the entity path. ConnectionString format: Endpoint=sb://namespace_DNS_Name;EntityPath=EVENT_HUB_NAME;SharedAccessKeyName=SHARED_ACCESS_KEY_NAME;SharedAccessKey=SHARED_ACCESS_KEY or Endpoint=sb://namespace_DNS_Name;EntityPath=EVENT_HUB_NAME;SharedAccessSignatureToken=SHARED_ACCESS_SIGNATURE_TOKEN

Parameters:

namespaceConnectionString - connections string of the ServiceBus namespace. This doesn't include the entity path.

entityPath - path to the entity within the namespace

ConnectionStringBuilder

public ConnectionStringBuilder(String namespaceName, String entityPath, String sharedAccessSingature)

Creates a new instance from namespace, entity path and already generated SAS token.

Parameters:

namespaceName - Namespace name (dns suffix - ex: .servicebus.windows.net is not required)

entityPath - Entity path. For queue or topic, use name. For subscription use <topicName>/subscriptions/<subscriptionName>
