Message.GetBody();序列化循环
我在序列化来自 Windows Azure ServiceBus 的消息时遇到问题。
当我调用“message.GetBody();”时方法它最终会进入某种循环，这使得我的azure模拟器分配机器上的所有可用内存。
我的代码：
Microsoft.ServiceBus.Messaging.BrokeredMessage message;
while (true)
{
// SB is an instance of a class which let me receive a BrokeredMessage through its ReceiveMessage method.
message = SB.ReceiveMessage("orders");
if (message == null)
{
break;
}
// This ends up allocating lots of memory until the debugger crashes.
Procurement.TestOrder torder = message.GetBody<Procurement.TestOrder>();
}
使用的类：
[MessageContract(IsWrapped=false)]
public class TestOrder
{
[MessageBodyMember]
public int companyId { get; set; }
}
我还尝试使用 TestOrder-Class 上的 [DataContract] 和 [DataMember] 属性。
顺便说一句，该消息是一个非常简单的 XML 文件，没有任何命名空间从 BizTalk 进入 azure 中的队列。
这可能存在一些小缺陷，但我没有看到序列化器陷入循环的任何原因。
提前致谢！
I have a problem with serializing a message from Windows Azure ServiceBus.
When i Call the "message.GetBody();" method it ends up in some kind of loop which makes my azure-emulator allocate all memory available on the machine.
My code:
Microsoft.ServiceBus.Messaging.BrokeredMessage message;
while (true)
{
// SB is an instance of a class which let me receive a BrokeredMessage through its ReceiveMessage method.
message = SB.ReceiveMessage("orders");
if (message == null)
{
break;
}
// This ends up allocating lots of memory until the debugger crashes.
Procurement.TestOrder torder = message.GetBody<Procurement.TestOrder>();
}
The Used Class:
[MessageContract(IsWrapped=false)]
public class TestOrder
{
[MessageBodyMember]
public int companyId { get; set; }
}
I have also tried using the [DataContract] and [DataMember] attributes on the TestOrder-Class.
By the way, the message is a pretty simple XML-File without any namespaces coming from BizTalk into a queue in azure.
There might be some small flaws with this but i dont see any reason for the serializer to get stuck in a loop.
Thanks in advance!

使用
[DataContract]和[DataMember]尝试反序列化时收到什么错误？如果您只是执行Stream s = message.GetBody(); s包含什么？如果字符串的有效负载是文本/XML，而不是二进制序列化 XML，您可能需要传入 DataContractSerializer，如下所示：
What error do you receive when using
[DataContract]and[DataMember]to attempt to deserialize? If you just doStream s = message.GetBody<Stream>();what doesscontain?If the payload of the string is text/XML as opposed to binary serialized XML you'll probably need to pass in a DataContractSerializer like this:
要进行快速测试，请尝试在 message.GetBody 之后添加 Thread.Sleep(10)。我在本地 Azure 模拟器上遇到了类似的问题，这个简单的技巧解决了它。
To make a quick test try to add a Thread.Sleep(10) after the message.GetBody. I had a similar problem with the local Azure emulator, and this simple trick solved it.
