XML正確序列化但無法反序列化數組對象

Question

我有一個需要序列化XML的項目。 Java庫和C＃.NET 4.0庫均以我的XSD為目標。 我的C＃庫似乎在反序列化特定XML時遇到問題。

這是有問題的XML。

我正在用此代碼測試C＃庫。

using FishbowlSDK;

using System.Collections.Generic;
using System.Diagnostics;
using System.IO;
using System.Linq;
using System.Text;
using System.Text.RegularExpressions;

{
    class Program
    {
        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);
        }


    }
}

這是完整XSD的片段。 只是銷售訂單對象。

    </xs:complexType>
</xs:element>

這是C＃庫中的目標代碼。 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;
    }
}

這就是我的測試代碼輸出的內容。

Unknown Element
    PriceIsHomeCurrency true
     LineNumber: 25
     LinePosition: 52
Unknown Element
    BillTo 
     LineNumber: 26
     LinePosition: 14
Unknown Element
    Ship 
     LineNumber: 27
     LinePosition: 12
Unknown Element
    Cost 0
     LineNumber: 28
     LinePosition: 19
Unknown Element
    Items 
      <SalesOrderItem xmlns="FishbowlSDK">
        <ID>3725</ID>
        <ProductNumber />
        <SOID>-1</SOID>
        <Description>Adjustment Amount</Description>
        <Taxable>false</Taxable>
        <Quantity>1</Quantity>
        <ProductPrice>0.07</ProductPrice>
        <TotalPrice>0.07</TotalPrice>
        <UOMCode>ea</UOMCode>
        <ItemType>11</ItemType>
        <Status>-1</Status>
        <Note />
        <QuickBooksClassName />
        <NewItemFlag>true</NewItemFlag>
        <LineNumber>1</LineNumber>
        <AdjustmentAmount>0</AdjustmentAmount>
        <AdjustPercentage>0</AdjustPercentage>
        <QtyFulfilled>0</QtyFulfilled>
        <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＃知道有一個已知元素。 但為什么？ 因為我可以以編程方式生成銷售訂單對象，並且XML已正確序列化。

Answer 1

我發現了問題。 它是“ PriceIsHomeCurrency”的Unknown元素，因為該對象的順序現在不同於反序列化程序預期的順序，因此認為Items元素是未知的。 修復此未知元素可解決序列化問題。
