MessagePropertyFilter.HashAlgorithm Property

Definition

Namespace:

System.Messaging

Assembly:

System.Messaging.dll

Gets or sets a value that indicates whether to retrieve HashAlgorithm property information when receiving or peeking a message.

public:
 property bool HashAlgorithm { bool get(); void set(bool value); };

[System.Messaging.MessagingDescription("MsgHashAlgorithm")]
public bool HashAlgorithm { get; set; }

[<System.Messaging.MessagingDescription("MsgHashAlgorithm")>]
member this.HashAlgorithm : bool with get, set

Public Property HashAlgorithm As Boolean

Property Value

Boolean

true to receive HashAlgorithm information; otherwise, false. The default is false.

Examples

The following code example demonstrates the use of the HashAlgorithm property.

// Set the queue's MessageReadPropertyFilter property 
// to enable the message's HashAlgorithm property.
queue->MessageReadPropertyFilter->HashAlgorithm = true;

// Peek at the message. Time out after ten seconds 
// in case the message was not delivered.
orderMessage = queue->Peek(TimeSpan::FromSeconds(10.0));

// Display the value of the message's 
// HashAlgorithm property.
Console::WriteLine("Message.HashAlgorithm: {0}", 
    orderMessage->HashAlgorithm);

// Set the queue's MessageReadPropertyFilter property to enable the
// message's HashAlgorithm property.
queue.MessageReadPropertyFilter.HashAlgorithm = true;

// Peek at the message. Time out after ten seconds in case the message
// was not delivered.
orderMessage = queue.Peek(TimeSpan.FromSeconds(10.0));

// Display the value of the message's HashAlgorithm property.
Console.WriteLine("Message.HashAlgorithm: {0}",
    orderMessage.HashAlgorithm);

Remarks

The HashAlgorithm property of the Message class identifies the hashing algorithm Message Queuing uses when authenticating messages. The hashing algorithm is also used when creating a digital signature for a message.
