Question

我从Web服务中获取了一些XML。我建立了一些反序列化的类。它正在部分工作；我得到了任何SavingType对象的原始成员的期望值。

正如代码所示，我得到了一个Saving对象，该对象应该有多个，并且其字段为null。我在Savings成员上有一些评论属性（也许我应该更改这些名称）。这些属性似乎应该比我在上面没有注释的XmlElement更正确，但是当我使用它们时，反序列化对象的Savings成员始终是一个空数组。我的错误在哪里？

<Product xmlns="http://schemas.datacontract.org/2004/07/mInitechService" xmlns:i="http://www.w3.org/2001/XMLSchema-instance">
    ...
    <AdvSaving>
        <SavingType>...</SavingType>
        <SavingType>...</SavingType>
        <SavingType>
            <Savings>
                <Saving>
                    <apy>0.06</apy>
                    <dailyBalance>0.01</dailyBalance>
                    <divRate>0.06</divRate>
                    <name>Ultimate Checking </name>
                </Saving>
                <Saving>
                    <apy>0.10</apy>
                    <dailyBalance>10,000.00</dailyBalance>
                    <divRate>0.10</divRate>
                    <name>Ultimate Checking</name>
                </Saving>
                <Saving>
                    <apy>0.06</apy>
                    <dailyBalance>0.01</dailyBalance>
                    <divRate>0.06</divRate>
                    <name>Business Rewards Checking</name>
                </Saving>
            </Savings>

    </AdvSaving>
    <effectiveDate>Rates effective from 11/01/2018 through 11/30/2018</effectiveDate>

和类：

namespace InitechServiceEntities
{
    [XmlType(AnonymousType = true, Namespace = "http://schemas.datacontract.org/2004/07/mInitechService")]
    [XmlRoot(Namespace = "http://schemas.datacontract.org/2004/07/mInitechService", IsNullable = false)]
    public class Product
    {
        //...
        [XmlArrayItem("SavingType", typeof(SavingType), IsNullable = false)]
        public SavingType[] AdvSaving;
        [XmlElement("effectiveDate")]
        public string effectiveDate;
    }

    [XmlType("SavingType")]
    public class SavingType
    {
        [XmlElement("savingsTypeName")]
        public string savingsTypeName;
        [XmlElement("savingsMinBal")]
        public string savingsMinBal;
        [XmlElement("savingNote")]
        public string savingNote;
        [XmlElement("Savings")]
        //[XmlArray(ElementName = "Savings")]
        //[XmlArrayItem(Type = typeof(Saving))]
        public Saving[] Savings;
    }

    [XmlType("Saving")]
    public class Saving
    {
        [XmlElement("name")]
        public string name;
        [XmlElement("dailyBalance")]
        public decimal dailyBalance;
        [XmlElement("divRate")]
        public decimal divRate;
        [XmlElement("apy")]
        public decimal apy;
    }
}

您的数据模型有两个问题：

在SavingType中，Savings数组必须标记为[XmlArray("Savings")]，以指示该集合已由外部容器元素<Savings>和内部元素{ {1}}：
```
<Saving>
```
您最初是用这种方式标记数组的，然后将其注释掉并用[XmlArray(ElementName = "Savings")]替换，这表明该集合应该在没有外部元素的情况下进行序列化-这不能反映实际的XML。
固定为＃1，您将遇到第二个问题，即由于逗号的存在，// FIXED [XmlArray("Savings")] public Saving[] Savings;的值10,000.00无法解析为decimal ，因此反序列化期间会引发异常。

要解决此问题，您需要将<dailyBalance>10,000.00</dailyBalance>更改为Saving.dailyBalance，或引入一个代理属性来手动进行解析：
```
string
```

因此，修改后的固定类型如下：

// FIXED
[XmlElement("dailyBalance")]
public string dailyBalance;

顺便说一句，通过在内存中构造模型实例，然后序列化为XML，这些问题通常很容易诊断。当将生成的XML与要反序列化的XML进行比较时，结构上的任何差异都将表明反序列化代码在哪里存在bug。
