Gets or sets a value that indicates whether the sender ID should be attached to the message.
Assembly: System.Messaging (in System.Messaging.dll)
The message queue is filtered to ignore the property.
The SenderId property is an array of bytes that represents the identifier of the sending user. The sender ID is set by Message Queuing and is used by the receiving Queue Manager to verify whether the sender has access rights to a queue.
The absence of the sender ID is an indication by the sending application that Message Queuing should not validate the message's sender nor verify the sender's access rights to the receiving queue. The SenderId is trustworthy only if the message was authenticated when it reached the destination queue. The message is rejected when it reaches the destination queue if the queue accepts only authenticated messages and either the UseAuthentication or the AttachSenderId property is false.
The following code example gets and sets the value of a message's property.
