Question

我正在尝试使用datacontractjson序列化程序向azure服务总线发送消息。我经常收到以下错误消息

未处理的异常：System.InvalidOperationException：无法序列化邮件，因为它的正文流已被部分使用。

这是我的代码

[DataContract]
class flow
{
    [DataMember]
    public string srcip {get; set;}
    [DataMember]
    public string dstip {get; set;}
}

主要代码：

class Program
   {
        static void Main(string[] args)
       {
        string connectionString = "XXXXXX";

        MessagingFactory factory = MessagingFactory.CreateFromConnectionString(connectionString);

        flow f = new flow()
        {
            srcip = "10.1.1.1",
            dstip = "20.1.1.1"
        };


        //Sending a message

        MessageSender testQueueSender = factory.CreateMessageSender("XXXXX");

        MemoryStream stream1 = new MemoryStream();
        DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(flow));
        ser.WriteObject(stream1, f);

        BrokeredMessage message = new BrokeredMessage(stream1);

        testQueueSender.Send(message);

        Console.WriteLine("Message(s) sent.");





        Console.WriteLine("Done, press a key to continue...");

        Console.ReadKey();
    }
}

}

在尝试发送消息之前，看起来流位置并不总是重置为0。如果您尝试这样做，它应该可靠地发送：

MessageSender testQueueSender = factory.CreateMessageSender("testpath");

MemoryStream stream1 = new MemoryStream();
DataContractJsonSerializer ser = new DataContractJsonSerializer(typeof(flow));
ser.WriteObject(stream1, f);

stream1.Position = 0;

BrokeredMessage message = new BrokeredMessage(stream1);

testQueueSender.Send(message);

服务总线System.InvalidOperationException
