MessagePropertyFilter.HashAlgorithm 属性

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 HashAlgorithm 属性信息。

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

属性值

Boolean

如果接收 HashAlgorithm 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 HashAlgorithm 属性。

// 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);

注解

HashAlgorithm类的 Message 属性标识消息队列在对消息进行身份验证时使用的哈希算法。 为消息创建数字签名时，也使用哈希算法。
