This instance property specifies the correlation identifier of the message to be dequeued.

Declaration

// C#
public string Correlation {get;set;}

Property Value

A string.

Remarks

This property specifies the identification of the message to be dequeued. Special pattern matching characters, such as the percent sign (%) and the underscore (_) can be used. If more than one message satisfies the pattern, then the order of dequeuing is undetermined.

The maximum length of Correlation is 128.

MessageId and Correlation are two independent identifiers. While MessageId is unique for a message, a group of messages can be assigned the same Correlation. Also, pattern matching is possible only with Correlation.
