C#实现实体类和XML相互转换

一、实体类转换成xml

将实体类转换成xml需要使用xmlserializer类的serialize方法，将实体类序列化

public static string xmlserialize<t>(t obj)
{
  using (stringwriter sw = new stringwriter())
  {
    type t= obj.gettype();    
    xmlserializer serializer = new xmlserializer(obj.gettype());
    serializer.serialize(sw, obj);
    sw.close();
    return sw.tostring();
  }
}

示例：

1、定义实体类

[system.xml.serialization.xmltypeattribute(anonymoustype = true)]
 [system.xml.serialization.xmlrootattribute(namespace = "", isnullable = false)]
 public class request
 {

  public string system { get; set; }
  public string securitycode { get; set; }
  public patientbasicinfo patientinfo { get; set; }  
 }

 /// <remarks/>
 [system.xml.serialization.xmltypeattribute(anonymoustype = true)]
 public partial class patientbasicinfo
 {
  public string patientno { get; set; }
  public string patientname { get; set; }
  public string phoneticize { get; set; }
  public string sex { get; set; }
  public string birth { get; set; }
  public string birthplace { get; set; }
  public string country { get; set; }
  public string nation { get; set; }
  public string idnumber { get; set; }
  public string securityno { get; set; }
  public string workunits { get; set; }
  public string address { get; set; }
  public string zipcode { get; set; }
  public string phone { get; set; }
  public string contactperson { get; set; }
  public string contactship { get; set; }
  public string contactpersonadd { get; set; }
  public string contactpersonphone { get; set; }
  public string operationcode { get; set; }
  public string operationname { get; set; }
  public string operationtime { get; set; }
  public string cardno { get; set; }
  public string changetype { get; set; }

 }

2、给实体类赋值，并通过序列化将实体类转换成xml格式的字符串

request patientin = new request();
   patientin.system = "his";
   patientin.securitycode = "his5";

   patientbasicinfo basicinfo = new patientbasicinfo();
   basicinfo.patientno = "1234";
   basicinfo.patientname = "测试";
   basicinfo.phoneticize = "";
   basicinfo.sex = "1";
   basicinfo.birth = "";
   basicinfo.birthplace = "";
   basicinfo.country = "";
   basicinfo.nation = "";
   basicinfo.idnumber = "";
   basicinfo.securityno = "";
   basicinfo.workunits = "";
   basicinfo.address = "";
   basicinfo.zipcode = "";
   basicinfo.phone = "";
   basicinfo.contactship = "";
   basicinfo.contactpersonphone = "";
   basicinfo.contactpersonadd = "";
   basicinfo.contactperson = "";
   basicinfo.changetype = "";
   basicinfo.cardno = "";
   basicinfo.operationcode = "";
   basicinfo.operationname = "";
   basicinfo.operationtime = "";

   patientin.patientinfo = basicinfo;

   //序列化
   string strxml = xmlserializehelper.xmlserialize<request>(patientin);

3、生成的xml实例

<?xml version="1.0" encoding="utf-16"?>
<request xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:xsd="http://www.w3.org/2001/xmlschema">
 <system>his</system>
 <securitycode>his5</securitycode>
 <patientinfo>
 <patientno>1234</patientno>
 <patientname>测试</patientname>
 <phoneticize />
 <sex>1</sex>
 <birth />
 <birthplace />
 <country />
 <nation />
 <idnumber />
 <securityno />
 <workunits />
 <address />
 <zipcode />
 <phone />
 <contactperson />
 <contactship />
 <contactpersonadd />
 <contactpersonphone />
 <operationcode />
 <operationname />
 <operationtime />
 <cardno />
 <changetype />
 </patientinfo>
</request>

二、将xml转换成实体类

把xml转换成相应的实体类，需要使用到xmlserializer类的deserialize方法，将xml进行反序列化。

public static t deserializer<t>(string strxml) where t:class
{
  try
 {
   using (stringreader sr = new stringreader(strxml))
   {
    xmlserializer serializer = new xmlserializer(typeof(t));
    return serializer.deserialize(sr) as t;
   }
  }
  catch (exception ex)
  {
   return null;
  }
}

示例：

将上例中序列化后的xml反序列化成实体类

//反序列化
request r = xmlserializehelper.deserializer<request>(strxml);
