我们正在合作的Java商店供应商需要我们（.NET商店）提供符合他们发送给我们的WSDL的RESTful服务。我们返回的XML与供应商的期望之间存在一些差异。我的过程从根本上是错误的，还是Java和.NET进行序列化的方式只是不同？
我的过程：
该合同第一个想法是新的给我，但在这样的职位上覆盖好这个。因此，只要具备一点知识，我就可以通过SvcUtil.exe运行WSDL和关联的.XSD来生成C＃（下面的一些相关摘录），并且我将这些类型用作服务的返回类型。
我也尝试过使用wsdl.exe和生成代码xsd.exe，但是都没有明显改变结果。
区别：
结果和代码摘录：
供应商希望该服务返回如下所示的消息：

在供应商的大量帮助下，我们最终使这项工作奏效。从那以后，我离开了组织-但我保留了代码的副本。
我们使用了它-https://msdn.microsoft.com/zh-cn/library/aa395223(v=vs.110).aspx-我们的完整实现如下。
我们用以下内容装饰了服务接口DispatchByBodyElementBehavior：
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.ServiceModel", "4.0.0.0")]
[ServiceContract(Namespace = "http://vendor.com/project/wsdl"), XmlSerializerFormat, DispatchByBodyElementBehavior]
public interface IContractFirstService
我们还必须修改SvcUtil.exe生成的代码，但不能进行大量修改。只有几个地方需要调整。与数组限制有关。对不起，我不记得了。我很确定从编译/运行时错误中可以做什么是很明显的。
这是我们的实现方式DispatchByBodyElementBehavior：
using System;
using System.Diagnostics;
using System.ServiceModel.Channels;
using System.Collections.Generic;
using System.ServiceModel.Description;
using System.ServiceModel.Dispatcher;
using System.Xml;
/*
* This code was written based on the sample provided at http://msdn.microsoft.com/en-us/library/aa395223(v=vs.110).aspx.
* The purpose of this is to allow dispatching of the incoming SOAP requests based on the payload XML element.
* This allows the more standard document/literal service contract design to be used and does not rely on SOAP actions.
