示例

下面的代码示例演示如何使用 SenderId 属性。

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

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

注解

SenderId类的 Message 属性主要由接收队列管理器在对消息进行身份验证时使用。 属性由消息队列设置，队列管理器使用来验证发送消息的人员以及发送者是否有权访问接收队列。
