Label Property

MessageQueue.Label Property

Gets or sets the queue description.

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

public string Label { get; set; }
/** @property */
public String get_Label ()

/** @property */
public void set_Label (String value)

public function get Label () : String

public function set Label (value : String)

Property Value

The label for the message queue. The default is an empty string ("").

Exception typeCondition

ArgumentException

The label was set to an invalid value.

MessageQueueException

An error occurred when accessing a Message Queuing method.

The maximum length of a message queue label is 124 characters.

The Label property does not need to be unique across all queues. However, if multiple queues share the same Label, you cannot use the Send(Object) method to broadcast a message to all of them. If you use the label syntax for the Path property when you send the message, an exception will be thrown if the Label is not unique.

The following table shows whether this property is available in various Workgroup modes.

    queue.Label);

// Set the queue's Label property value.
