【问题描述】：

首先我想说我知道这项古老的技术，如果由我来决定，生活会有所不同。我对这项旧技术比较陌生，我正在扩展工作中的现有服务，我遇到了一个奇怪的问题。我有 3 个服务端点，其中 2 个按预期工作，但我对第三个的问题是“框架”无法反序列化 xml 请求。

<?xml version="1.0" encoding="UTF-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <soap:Body>
      <UpdateSale xmlns="http://tokenws.netgen.co.za/">
         <p_objrequest>
            <transactionTypeId>1</transactionTypeId>
            <tenderTypeId>1</tenderTypeId>
            <standardHeader>
               <requestId xmlns="">1_8</requestId>
               <localeId xmlns="" />
               <systemId xmlns="">asdf</systemId>
               <batchReference xmlns="">11</batchReference>
            </standardHeader>
            <account>
               <accountId xmlns="">123</accountId>
               <pin xmlns="" >123</pin>
            </account>
            <amount>
               <valueCode xmlns="">ZAR</valueCode>
               <enteredAmount xmlns="">30</enteredAmount>
               <nsfAllowed xmlns="">N</nsfAllowed>
            </amount>
            <lineItems>
               <LineItem>
                  <productCode>1</productCode>
                  <categoryCode>1</categoryCode>
                  <qty>1</qty>
                  <price>50</price>
                  <discountedPrice>0</discountedPrice>
                  <description>Buffet Breakfast</description>
               </LineItem>
            </lineItems>
         </p_objrequest>
         <netCredentials>
            <UserName xmlns="http://tempuri.org/">123</UserName>
            <Password xmlns="http://tempuri.org/">123</Password>
         </netCredentials>
      </UpdateSale>
   </soap:Body>
</soap:Envelope>

上面是 xml，netCredentials 被正确反序列化，但 p_objrequest 为空。

如果您遇到过这个问题并解决了它，如果您能引导我走向正确的方向，我将不胜感激。

提前致谢。

【问题讨论】：

这可能没什么，但你试过切换顺序吗？将Password 放在UserName 之前？
我需要去上课。要么 a 属性不公开，要么缺少其中一个命名空间：xmlns="tokenws.netgen.co.za" 或 "tempuri.org"
@jdweng 我已经通过放置类更新了帖子
@christophano 我有，它没有影响，仍然正确反序列化它但 p_objrequest 失败。

标签： c# xml web-services wcf asmx

【解决方案1】：

标签名称和类/属性名称必须匹配，包括大小写。见下文：

    [XmlRoot(ElementName= "UpdateSale", Namespace="http://tokenws.netgen.co.za/")]
    public class Sale
    {
    }
    [XmlRoot(ElementName= "netCredentials")]
    public class NetCredentials
    {
        [XmlElement(ElementName="UserName",Namespace="http://tempuri.org/")]
        public Name userName { get; set;} 
        [XmlElement(ElementName="Password",Namespace="http://tempuri.org/")]
        public Name password { get; set;} 
    }
    public class Name
    {
        [XmlText]
        public string name { get; set;}
    }
