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://HdhCmsTestw3.org/2001/XMLSchema-instance" xmlns:xsd = "http://HdhCmsTestw3.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);
