[C#]记一次解析XML转对象的笔记
项目中调用第三方API，返回格式是XML字符串，需要将XML反序列化为对象，格式如下：
<?xml version="1.0"?>
<Response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" totalCount="" resultCode="ABC" resultMessage="测试">
<profile lastName="李" firstName="爽" dateOfBirth="XX0816" age="" gender="" address="浙江省 杭州富阳市 东州工业园区3号路1号杭州龙盛工贸有限公" email="htlslll@163.com" cellEmail="" socialMedia="" homePhone="" cellPhone="" contactabiltyMail="" contactabiltyEmail="" contactabiltyCellEmail="" contactabiltyHomePhone="" contactabiltyCellPhone="" contactabiltyText="" contactabiltySocialMedia="" vipLevel="" memberId="OC540C00016824" saAccount="" classa="小姐" homeStoreCode="OC54" />
<purchaseHistory>
<departmentPurchase totalLifeTimeSale="" totalTYAmount="" lastTxn="" totalTYUnitCnt="" firstTxn="">
<department categoryName="D08" tyAmount="" tyUnitCnt="" />
<department categoryName="D01" tyAmount="" tyUnitCnt="" />
<department categoryName="D02" tyAmount="" tyUnitCnt="" />
</departmentPurchase>
<ratePurchase totalLyAmount="" totalLyRate="" totalTyAmount="" totalTyRate="" totalLifeTimeAmount="" totalLifeTimeRate="">
<rate categoryName="Retail" lyAmount="" lyRate="" lyToDate="" tyAmount="" tyRate="" tyToDate="" lifeTimeAmount="" lifeTimeRate="" lyTyChange="" />
</ratePurchase>
<storeRatePurchase>
<storeRate />
</storeRatePurchase>
</purchaseHistory>
<vipStatus issueDate="" issueShop="OC54" ptsToUpgrade="" expiryDate="" upgradeShop="" ptsToRenew="" />
<comments comment="第一场雪" />
</Response>
按照这个格式我需要定义相应的对象来接收，定义如下：

解析代码如下
private static System.Xml.Serialization.XmlSerializer Serializer;
/// <summary>
/// 指定XML字符串序列化成对象
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="xml"></param>
/// <returns></returns>
public static T DeserializeForXml<T>(string xml) where T : class, new()
{
System.IO.StringReader stringReader = null;
try
{
Serializer = Serializer ?? new XmlSerializer(typeof(T));
stringReader = new StringReader(xml);
T result = Serializer.Deserialize(stringReader) as T;
return result;
}
finally
{
if ((stringReader != null))
{
stringReader.Dispose();
}
}
}
调用方式：
var rpXML = AcxiomXMLHelper.DeserializeForXml<CustomerDetails.Response>(returnXML);
好了，接下来就出现了问题
departmentPurchase 下面的department始终是没有数据，调试好久都找不到问题出现在哪里。
尝试找解决的办法，先实例化一个Response对象序列化后写入文件，再将文件内容读出来反序列化出来
Response response = new Response
{
totalCount = "",
resultCode = "ABC",
resultMessage = "测试",
profile = new profile { lastName = "李", firstName = "爽", dateOfBirth = "XX0816", age = "", gender = "", address = "浙江省 杭州富阳市 东州工业园区3号路1号杭州龙盛工贸有限公", email = "htlslll@163.com", cellEmail = "", socialMedia = "", homePhone = "", cellPhone = "", contactabiltyMail = "", contactabiltyEmail = "", contactabiltyCellEmail = "", contactabiltyHomePhone = "", contactabiltyCellPhone = "", contactabiltyText = "", contactabiltySocialMedia = "", vipLevel = "", memberId = "OC540C00016824", saAccount = "", classa = "小姐", homeStoreCode = "OC54" },
comments = new comments { comment = "第一场雪" },
purchaseHistory = new purchaseHistory
{
departmentPurchase = new departmentPurchase
{
totalTYAmount = "",
totalTYUnitCnt = "",
firstTxn = "",
lastTxn = "",
totalLifeTimeSale = "",
department = new List<department> {
new department { categoryName = "D08", tyAmount = "", tyUnitCnt = "" },
new department { categoryName = "D01", tyAmount = "", tyUnitCnt = "" },
new department { categoryName = "D02", tyAmount = "", tyUnitCnt = "" }
}
},
ratePurchase = new ratePurchase
{
totalLyAmount = "",
totalLyRate = "",
totalTyAmount = "",
totalTyRate = "",
totalLifeTimeAmount = "",
totalLifeTimeRate = "",
rate = new rate { categoryName = "Retail", lyAmount = "", lyRate = "", lyToDate = "", tyAmount = "", tyRate = "", tyToDate = "", lifeTimeAmount = "", lifeTimeRate = "", lyTyChange = "" }
},
storeRatePurchase = new storeRatePurchase { storeRate = string.Empty }
},
vipStatus = new vipStatus { issueDate = "", issueShop = "OC54", ptsToUpgrade = "", expiryDate = "", upgradeShop = "", ptsToRenew = "" }
}; FileStream stream = new FileStream(@"d:\xmlFormat.xml", FileMode.Create);
XmlSerializer xmlserilize = new XmlSerializer(typeof(Response));
xmlserilize.Serialize(stream, response); stream.Close(); using (FileStream xmlStream = new FileStream(@"d:\xmlFormat.xml", FileMode.Open))
{
using (XmlReader xmlReader = XmlReader.Create(xmlStream))
{
XmlSerializer serializer = new XmlSerializer(typeof(Response));
Response res = serializer.Deserialize(xmlReader) as Response;
}
}
代码中res是反序列化的结果，数据都正确。这就有点恼火了，怎么办呢？
比较我生成的文件和API返回的XML：
下面是我生成的XML格式
<Response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" totalCount="" resultCode="ABC" resultMessage="测试">
<profile lastName="李" firstName="爽" dateOfBirth="XX0816" age="" gender="" address="浙江省 杭州富阳市 东州工业园区3号路1号杭州龙盛工贸有限公" email="htlslll@163.com" cellEmail="" socialMedia="" homePhone="" cellPhone="" contactabiltyMail="" contactabiltyEmail="" contactabiltyCellEmail="" contactabiltyHomePhone="" contactabiltyCellPhone="" contactabiltyText="" contactabiltySocialMedia="" vipLevel="" memberId="OC540C00016824" saAccount="" classa="小姐" homeStoreCode="OC54" />
<purchaseHistory>
<departmentPurchase totalLifeTimeSale="" totalTYAmount="" lastTxn="" totalTYUnitCnt="" firstTxn="">
<department>
<department categoryName="D08" tyAmount="" tyUnitCnt="" />
<department categoryName="D01" tyAmount="" tyUnitCnt="" />
<department categoryName="D02" tyAmount="" tyUnitCnt="" />
</department>
</departmentPurchase>
<ratePurchase totalLyAmount="" totalLyRate="" totalTyAmount="" totalTyRate="" totalLifeTimeAmount="" totalLifeTimeRate="">
<rate categoryName="Retail" lyAmount="" lyRate="" lyToDate="" tyAmount="" tyRate="" tyToDate="" lifeTimeAmount="" lifeTimeRate="" lyTyChange="" />
</ratePurchase>
<storeRatePurchase>
<storeRate />
</storeRatePurchase>
</purchaseHistory>
<vipStatus issueDate="" issueShop="OC54" ptsToUpgrade="" expiryDate="" upgradeShop="" ptsToRenew="" />
<comments comment="第一场雪" />
</Response>
仔细比对发现问题
在departmentPurchase 节点下我多了一层department节点，可我是按照接口的结果定义的对象啊
[System.CodeDom.Compiler.GeneratedCodeAttribute("System.Xml", "4.0.30319.34209")]
[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = true)]
public class departmentPurchase
{
[System.Xml.Serialization.XmlAttributeAttribute()]
public string totalTYAmount { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string totalTYUnitCnt { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string firstTxn { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string lastTxn { get; set; }
[System.Xml.Serialization.XmlAttributeAttribute()]
public string totalLifeTimeSale { get; set; }
[System.Xml.Serialization.XmlElementAttribute("department", typeof(List<department>), Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = )]
public List<department> department { get; set; }
}
怎么搞呢？在网上不停的找答案，最终都无解。但是没有放弃，答案也往往在快要放弃的时候出现
我尝试的修改了department的定义
修改前
[System.Xml.Serialization.XmlElementAttribute("department", typeof(List<department>), Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = )]
public List<department> department { get; set; }
修改后
[System.Xml.Serialization.XmlElementAttribute("department", typeof(department), Form = System.Xml.Schema.XmlSchemaForm.Unqualified, Order = )]
public List<department> department { get; set; }
重新运行，奇迹出现
<?xml version="1.0"?>
<Response xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" totalCount="" resultCode="ABC" resultMessage="测试">

</Response>
问题解决。
原因就出在解析XML节点的
typeof(department) 与 typeof(List<department>)
