使用XmlSerializerFormat时WCF服务请求为空

我正在编写基于旧soap服务的WSDL的WCF服务。我使用svcutil来生成服务合同并做了一些更改以匹配我所托管的站点，但是当我从测试客户端调用服务时，请求对象将作为空值进入。使用XmlSerializerFormat时WCF服务请求为空

该服务正在返回的响应也正在序列化不正确，我敢肯定是相关的。但我不明白为什么它没有正确的序列化和反序列化。

这里的服务合同：

    public ApuService()

     _handler = EngineContext.Current.Resolve<IApuServiceHandler>(); 
     _settingService = EngineContext.Current.Resolve<ISettingService>(); 
    } 

    public Response check(Request request) 
    { 
     if (Authorized(request)) 
      return _handler.ProcessRequest(request); 
     return _handler.ErrorResponse("Invalid credentials"); 
    } 

    protected bool Authorized(Request request) 
    { 
     if (request == null || request.header == null) 
      return false; 

     var settings = _settingService.LoadSetting<ApuSettings>(0); 

     if (!string.Equals(request.header.account, settings.Username, StringComparison.InvariantCultureIgnoreCase)) 
      return false; 

     if (!string.Equals(request.header.id, settings.Password)) 
      return false; 

     return true; 
    } 
}

配置：

<configuration> 
    <system.web> 
    <compilation targetFramework="4.5.1" /> 
    </system.web> 

    <system.serviceModel> 
    <behaviors>

     <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" /> 
     </service> 
    </services> 
    </system.serviceModel> 
</configuration>

由服务接收（从OperationContext.Current.RequestContext请求.RequestMessage）：

    <s:Header xmlns:s="http://schemas.xmlsoap.org/soap/envelope/">

       </lookup>

当有人说'做了一些改变'时，我倾向于认为这是问题所在。 –

你检出了wsdl.exe吗？ https://msdn.microsoft.com/en-us/library/7h3ystb6(v=vs.100).aspx。旧的.asmx服务用于代理生成。取决于服务的年龄，您可能会得到不同的结果。 –

@JssDwt - 完全没有。我能够进一步修改服务以使用Data Contract序列化，并且它工作得很好。但是，我需要它来使用XML序列化。问题不在于修改。它知道修改它的正确方法。当我们开始说我们不能改变旧的（或在这种情况下是预生成的）代码来满足我们的需求时，对于编程世界来说这是一个糟糕的风景。 –

后续服务：原来我发布的服务合同就好了。这是请求的格式错误。而不是一个简单的内联XML结构，解串期待这样的：

它看起来像Response是一个局部类。有没有另一部分，也许在另一个文件？那个其他作品是可序列化的吗？ ResponseHeader和Part同样的问题？

我通常使用装饰者[Serializable]。

Part类中的public float list关键字列表可能存在问题。

任何部分都没有其他部分。数据对象已经被标记为Serializable（[System.SerializableAttribute（）]）。 C＃是一种区分大小写的语言，因此小写的“列表”不会与List类混淆。也不是“List”和“list”是c＃中的保留关键字。 –
