部分資訊涉及發行前產品,在發行之前可能會有大幅修改。 Microsoft 對此處提供的資訊,不做任何明確或隱含的瑕疵擔保。
取得或設定值,指出在接收或窺視訊息時是否要擷取 HashAlgorithm 屬性資訊。
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
屬性值
true
表示接收 HashAlgorithm 資訊,否則為 false
。 預設為 false
。

範例
下列程式代碼範例示範 屬性的使用 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);
// 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);
備註
類別 HashAlgorithm 的 Message 屬性會識別驗證訊息時所使用的哈希演算法消息佇列。 建立訊息的數字簽名時,也會使用哈希演算法。
