Message.IsLastInTransaction Property


Gets a value that indicates whether the message was the last message sent in a transaction.

Namespace:   System.Messaging
Assembly:  System.Messaging (in System.Messaging.dll)

public bool IsLastInTransaction { get; }

Property Value

Type: System.Boolean

true if the message was the last message sent in a single transaction; otherwise, false.

Exception Condition

The message has not been sent. This property can only be read on messages retrieved from a queue.


The message queue is filtered to ignore the IsLastInTransaction property.

Receiving applications use the IsLastInTransaction property to verify that a message was the last message sent in a single transaction to a single queue.

This property is available only with Message Queuing version 2.0 and later.

To verify transaction boundaries, you can use the IsLastInTransaction property along with two other properties: IsFirstInTransaction and TransactionId. Use the former to check whether a message was the first message sent in the transaction, and use the latter to retrieve the identifier of the transaction.

If only one message is sent in a transaction, the IsFirstInTransaction and IsLastInTransaction properties are both set to true.

The following code example displays the value of a message's IsLastInTransaction property.
