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

[<System.Messaging.MessagingDescription("MsgDestinationSymmetricKey")>]

示例

下面的代码示例演示如何使用 DestinationSymmetricKey 属性。

// Set the queue's MessageReadPropertyFilter property 
// to enable the message's 
// DestinationSymmetricKey property.
queue->MessageReadPropertyFilter->
    DestinationSymmetricKey = 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 
// DestinationSymmetricKey property.
Console::WriteLine(
    "Message.DestinationSymmetricKey: {0}", 
    orderMessage->DestinationSymmetricKey);

// Set the queue's MessageReadPropertyFilter property to enable the
// message's DestinationSymmetricKey property.
queue.MessageReadPropertyFilter.DestinationSymmetricKey = 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 DestinationSymmetricKey property.
Console.WriteLine("Message.DestinationSymmetricKey: {0}",
    orderMessage.DestinationSymmetricKey);

注解

DestinationSymmetricKey类的 Message 属性指定用于加密消息的对称密钥。 在发送应用程序加密的消息或将加密消息发送到外部队列时，这是必需的。

队列系统中存在外部队列，而不是Microsoft消息队列。 Microsoft消息队列通过连接器应用程序与此类队列通信。
