XML序列化正确但不能反序列化数组对象

我有一个需要序列化XML的项目。我的XSD是Java库和C＃.NET 4.0库的目标。我的C＃库似乎在反序列化特定的XML时遇到了问题。

这是有问题的XML。

我正在使用此代码测试我的C＃库。

    {
        static void Main(string[] args)
        {
            testSODeserialize();
        }

        public static void testSODeserialize()
        {
            String XML = Resource1.SOXMLTEST001;
            FbiXml fbixml = new FbiXml();
            System.Xml.Serialization.XmlSerializer xml = new System.Xml.Serialization.XmlSerializer(fbixml.GetType());
            xml.UnknownAttribute += new XmlAttributeEventHandler(Serializer_UnknownAttribute);
            xml.UnknownElement += new XmlElementEventHandler(Serializer_UnknownElement);
            String rs = XML;
            rs = rs.Replace(@"<FbiXml>", @"<FbiXml xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns=""FishbowlSDK"">");
            StringReader sr = new StringReader(rs);
            XmlTextReader xtr = new XmlTextReader(sr);
            FbiXml Response = (FbiXml)xml.Deserialize(xtr);
            SaveSORsType loadsors = (SaveSORsType)Response.FbiMsgsRs.Items[0];
            SalesOrder so = loadsors.SalesOrder;
            if (so.Items.Count == 0)
            {
                throw new Exception("This XML has Sales Order Items, but it deserialized none!");
            }            
        }

        private static void Serializer_UnknownAttribute(object sender, XmlAttributeEventArgs e)
        {
            Console.WriteLine("Unknown Attribute");
            Console.WriteLine("\t" + e.Attr.Name + " " + e.Attr.InnerXml);
            Console.WriteLine("\t LineNumber: " + e.LineNumber);
            Console.WriteLine("\t LinePosition: " + e.LinePosition);
        }

        private static void Serializer_UnknownElement(object sender, XmlElementEventArgs e)
        {
            Console.WriteLine("Unknown Element");
            Console.WriteLine("\t" + e.Element.Name + " " + e.Element.InnerXml);
            Console.WriteLine("\t LineNumber: " + e.LineNumber);
            Console.WriteLine("\t LinePosition: " + e.LinePosition);
        }


    }
}

这是完整XSD的片段。只是销售订单对象。

这是C＃Library中的目标代码。它是用xsd2code生成的。

[System.Xml.Serialization.XmlArrayAttribute(Order = 35)]
[System.Xml.Serialization.XmlArrayItemAttribute("SalesOrderItem", IsNullable = false)]
public List<SalesOrderItem> Items
{
    get
    {
        return this.itemsField;
    }
    set
    {
        this.itemsField = value;
    }
}

这是我的测试代码输出的内容。

Unknown Element
    PriceIsHomeCurrency true
     LineNumber: 25
     LinePosition: 52

     LineNumber: 26

     LineNumber: 27
     LinePosition: 12

    Cost 0
     LineNumber: 28
     LinePosition: 19

    Items 
      <SalesOrderItem xmlns="FishbowlSDK">

        <TotalPrice>0.07</TotalPrice>
        <UOMCode>ea</UOMCode>
        <ItemType>11</ItemType>
        <Status>-1</Status>
        <Note />
        <QuickBooksClassName />
        <NewItemFlag>true</NewItemFlag>

        <QtyPicked>0</QtyPicked>
        <TotalCost>0</TotalCost>
        <TaxID>1</TaxID>
        <TaxRate>0.1</TaxRate>
        <TaxCode>None</TaxCode>
      </SalesOrderItem>

     LineNumber: 55
     LinePosition: 13

所以我的c＃知道有一个已知的元素。但为什么？因为我可以以编程方式生成销售订单对象，并且XML已正确序列化。

1 个答案:

答案 0 :(得分：0)

我发现了这个问题。它是“PriceIsHomeCurrency”的未知元素，因为对象的顺序现在与反序列化程序所期望的不同，因此认为Items元素是未知的。修复此未知元素解决了序列化问题。
