WCF Datacontract，部分字段不反序列化 [英] WCF Datacontract, some fields do not deserialize

问题描述

问题:

我将 WCF 服务设置为来自外部系统的调用的端点.该调用正在发送纯 xml.我正在通过使用 RequestBuilder 从 Fiddler 向服务发送调用来测试系统.

I have a WCF service setup to be an endpoint for a call from an external system. The call is sending plain xml. I am testing the system by sending calls into the service from Fiddler using the RequestBuilder.

问题是我的所有字段都被反序列化，除了两个字段.price_retail 和 price_wholesale.

The issue is that all of my fields are being deserialized with the exception of two fields. price_retail and price_wholesale.

我错过了什么?所有其他字段反序列化都没有问题 - 服务响应.只是这些领域.

What am I missing? All of the other fields deserialize without an issue - the service responds. It is just these fields.

XML 消息:

<widget_conclusion>
    <list_criteria_id>123</list_criteria_id>
    <list_type>consumer</list_type>
    <qty>500</qty>
    <price_retail>50.00</price_retail>
    <price_wholesale>40.00</price_wholesale>
    <session_id>123456789</session_id>
</widget_conclusion>

服务方式:

public string WidgetConclusion(ConclusionMessage message)
{
    var priceRetail = message.PriceRetail;
}

消息类:

[DataContract(Name = "widget_conclusion", Namespace = "")]
public class ConclusionMessage  
{
    [DataMember(Name = "list_criteria_id")]
    public int CriteriaId  { get; set;}
    [DataMember(Name = "list_type")]
    public string ListType { get; set; }
    [DataMember(Name = "qty")]
    public int ListQuantity { get; set; }
    [DataMember(Name = "price_retail")]
    public decimal PriceRetail { get; set; }
    [DataMember(Name = "price_wholesale")]
    public decimal PriceWholesale { get; set; }
    [DataMember(Name = "session_id")]
    public string SessionId { get; set; }
}

推荐答案

字段在您的消息中的顺序错误.DataContracts 默认按字母顺序排列，不是 声明顺序；并期望 XML 元素按该顺序到达；乱序元素通常会被丢弃.

Fields are in the wrong order for your message. DataContracts default to Alphabetical ordering and not order of declaration; and expects XML elements to arrive in that order; Out of order elements are discarded usually.

修复您的合同​​以明确指定正确的顺序(使用 DataMemberAttribute 的 Order 属性)或确保您的客户以正确的顺序发送它们.

Either fix your contract to specify the right order explicitly (using the Order property of the DataMemberAttribute) or make sure your client sends them in the right one.
