MessagePropertyFilter.TransactionId 属性

  • 参考

定义

命名空间:
System.Messaging
程序集:
System.Messaging.dll

获取或设置一个值，该值指示接收或查看消息时是否检索 TransactionId 属性信息。

public:
 property bool TransactionId { bool get(); void set(bool value); };
[System.Messaging.MessagingDescription("MsgTransactionId")]
public bool TransactionId { get; set; }
[<System.Messaging.MessagingDescription("MsgTransactionId")>]
member this.TransactionId : bool with get, set
Public Property TransactionId As Boolean

属性值

Boolean

如果接收 TransactionId 信息，则为 true；否则为 false。 默认值为 false。

属性
MessagingDescriptionAttribute

示例

下面的代码示例演示如何使用 TransactionId 属性。

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

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

注解

TransactionId类的 Message 属性标识发送消息的事务。 在接收应用程序中使用此属性来验证消息是否已作为特定事务的一部分发送。
