Question

我希望在序列化后获取xml如下

<?xml version="1.0" encoding="windows-1252"?>
<OpenShipments xmlns="x-schema:C:\UPSLabel\OpenShipments.xdr">
<OpenShipment ShipmentOption="" ProcessStatus="">
    <ShipTo>
        <CompanyOrName>DARMOT Sp. z o.o</CompanyOrName>
        <Attention>DARMOT Sp. z o.o</Attention>
        <Address1>Ojca Damiana Tynieckiego 46</Address1>
        <Address2></Address2>
        <Address3>DarÂ3owo</Address3>
        <CountryTerritory>PL</CountryTerritory>
        <PostalCode>76-150</PostalCode>
        <CityOrTown>DarÂ3owo</CityOrTown>
        <StateProvinceCounty></StateProvinceCounty>
        <Telephone>943143185</Telephone>
    </ShipTo>
    <ShipmentInformation>
        <ServiceType>UPS Standard</ServiceType>
        <NumberOfPackages>1</NumberOfPackages>
        <DescriptionOfGoods>Remanufactured auto parts</DescriptionOfGoods>
        <BillingOption>PP</BillingOption>
    </ShipmentInformation>
    <Package>
        <PackageType>CP</PackageType>
        <Weight>1</Weight>
        <Reference1>OUR:AWP0021</Reference1>
        <Reference2>Job # 41149</Reference2>
        <DeclaredValue>
            <Amount>999</Amount>
        </DeclaredValue>
    </Package>
</OpenShipment>

为了从我的类中获取xml序列化后的上述xml，我写了几个类来完成工作。

我的完整c＃代码是：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;
using System.Xml;
using System.Xml.Serialization;

namespace XML2List
{
public partial class ShipMain : Form
{
    public ShipMain()
    {
        InitializeComponent();
    }

    public string Serialize<T>(T obj)
    {
        string xmlString = null;

        try
        {
            MemoryStream memoryStream = new MemoryStream();
            XmlSerializer xs = new XmlSerializer(typeof(T));
            XmlTextWriter xmlTextWriter = new XmlTextWriter(memoryStream, Encoding.UTF8);
            xs.Serialize(xmlTextWriter, obj);
            memoryStream = (MemoryStream)xmlTextWriter.BaseStream;
            xmlString = UTF8ByteArrayToString(memoryStream.ToArray()); return xmlString;
        }
        catch (Exception ex)
        {
            string xx = ex.Message.ToString();
        }
        return xmlString;
    }

    public string UTF8ByteArrayToString(byte[] characters)
    {
        UTF8Encoding encoding = new UTF8Encoding();
        string constructedString = encoding.GetString(characters);
        return (constructedString);
    }

    private void ShipMain_Load(object sender, EventArgs e)
    {
        OpenShipments op = new OpenShipments();
        op.xmlns=@"C:\UPSLabel\OpenShipments.xdr";
        op.OpenShipment.ShipmentOption = "";

        op.OpenShipment.ShipTo.Address2 = "";
        op.OpenShipment.ShipTo.Address3 = "DarÂ³owo";
        op.OpenShipment.ShipTo.CountryTerritory = "PL";
        op.OpenShipment.ShipTo.PostalCode = "76-150";
        op.OpenShipment.ShipTo.CityOrTown = "DarÂ³owo";
        op.OpenShipment.ShipTo.StateProvinceCounty = "DarÂ³owo";
        op.OpenShipment.ShipTo.Telephone = "943143185";
        op.OpenShipment.ShipmentInformation.ServiceType = "UPS Standard";
        op.OpenShipment.ShipmentInformation.NumberOfPackages = "1";
        op.OpenShipment.ShipmentInformation.DescriptionOfGoods = "Remanufactured auto parts";

        op.OpenShipment.Package.Weight = "1";
        op.OpenShipment.Package.Reference1 = "OUR:AWP0021";
        op.OpenShipment.Package.Reference2 = "Job # 41149";
        op.OpenShipment.Package.DeclaredValue.Amount = "999";
        string strRetXML=Serialize(op);
    }
}

}

public class DeclaredValue
{
    [XmlText]
    public string Amount { get; set; }
}
}

上面的代码我写的是获取我在顶部给出的xml输出。当我试图序列化课程，然后我得到。当XmlSerializer xs = new XmlSerializer（typeof（T））;行执行然后发生异常。错误是 - “有一个错误反映了类型'XML2List.OpenShipments'。”

我无法检测xml序列化时出错的原因。事件我不确定我写这个类的方式，它会生成我在顶部显示的所需xml。

所以请有人告诉我如何修复错误并在序列化后获取xml。还告诉我，在编写代码之后，我将获得所需的xml输出。

请详细讨论。

您需要检查内部异常。

xmlns是保留字，不应在OpenShipments上声明为属性。

根据documentation：

只有一个实例可以应用XmlTextAttribute类在课堂上。

您已将XmlText定义为ShipTo的所有属性，因此无法序列化。您只需要在一个属性上定义它。
