发送带有新库（Microsoft.Azure.ServiceBus）的消息，该消息由具有BodyType-字符串的旧库（Microsoft.ServiceBus.Messaging）读取 [英] Send a message with a new library (Microsoft.Azure.ServiceBus) that is read by an old library (Microsoft.ServiceBus.Messaging) with BodyType - String

问题描述

我有一段时间以前写过一个使用旧库的客户端，并在接收消息时调用 GetBody< string>（）来读取正文。

I have a client written for some time ago that uses the old library and does call GetBody<string>() to read the body when receiving messages.

现在我有了新的客户端 Microsoft.Azure.ServiceBus （发送消息），据我了解，它始终使用 Stream 。

Now I have the new client Microsoft.Azure.ServiceBus (sends messages) that as far as I understand always uses Stream.

因此，旧客户端会因为期望的字符串体类型而崩溃。我在相反的情况下发现了很多信息（新读者，老作家），但无法弄清楚如何使新客户端以所需格式发送数据。

So the old client just crashes as it expects string body type. I have found a lot of information on the opposite scenario (new reader, old writer), but cannot figure out how to make the new client send the data in required format.

推荐答案

该方案在此处。
您将需要按照以下方法来序列化消息：

The scenario is described here. You will need to serialize the message following this approach:

 var serializer = DataContractBinarySerializer<string>.Instance; 
 using (MemoryStream stream = new MemoryStream()) 
 {
     serializer.WriteObject(stream, some_string);
     var msg = new Message(stream.ToArray());
     var client = new Microsoft.Azure.ServiceBus.QueueClient(ConnectionString, Queue);
     await client.SendAsync(msg);
     await client.CloseAsync(); 
 }
