Detailed explanation of sample code for converting entity classes and XML in C#

This article mainly introduces in detail the information on converting entity classes and XML in C#. It has certain reference value. Interested friends can refer to it.

1. Convert entity classes to XML

To convert entity classes to XML, you need to use the Serialize method of the XmlSerializer class to serialize the entity class

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();
  }
}

Example:

1. Define entity class

[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. Assign a value to the entity class and convert the entity class into a string in XML format through serialization

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. Generated XML instance

##

<?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>

2. Convert XML into entities Class

To convert XML into the corresponding entity class, you need to use the Deserialize method of the XmlSerializer class to deserialize the XML.

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;
  }
}

Example:

Deserialize the serialized XML in the above example into an entity class

//反序列化
Request r = XmlSerializeHelper.DESerializer<Request>(strxml);
