# [C\#实现实体类和XML相互转换][C_XML] #

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);  
  
 三、将DataTable转换成XML  
复制代码  
  
  //将DataTable转换成XML  
 DataTable dt = new DataTable("MyTable");  
 //添加列  
 dt.Columns.Add("Id", typeof(int));  
 dt.Columns.Add("Name", typeof(string));  
 dt.Columns.Add("Sex", typeof(char));  
 //添加行  
 dt.Rows.Add(1, "小明", '1');  
 dt.Rows.Add(2, "小红", '2');  
 dt.Rows.Add(3, "小王", '2');  
 dt.Rows.Add(4, "测试", '2');  
 //序列化，将DataTable转换成XML格式的字符串  
 string strXML = XmlSerializeHelper.XmlSerialize <DataTable> (dt);  
  
复制代码  
  
四、将XML转换成DataTable  
  
1 //反序列化，将XML转换成字符串  
2 DataTable dtNew=  XmlSerializeHelper.DESerializer<DataTable>(strXML);  
  
五、将List集合转换成XML  
复制代码  
  
/// <summary>  
/// 测试类  
/// </summary>  
public class Student  
\{  
    public int Id \{ get; set; \}  
    public string Name \{ get; set; \}  
    public char Sex \{ get; set; \}  
    public int Age \{ get; set; \}  
\}  
  
//测试集合  
List<Student> list = new List<Student>()  
\{  
        new Student()\{Id=1,Name="小红",Sex='2',Age=20\},  
        new Student()\{Id=2,Name="小明",Sex='1',Age=22\},  
        new Student()\{Id=3,Name="小王",Sex='1',Age=19\},  
        new Student()\{Id=4,Name="测试",Sex='2',Age=23\}  
\};  
//序列化  
string strXML = XmlSerializeHelper.XmlSerialize<List<Student>>(list);  
  
复制代码  
  
六、将XML转换成集合  
  
使用上面例子中集合转换成的XML进行反序列化。  
  
 //反序列化  
 List<Student> listStu = XmlSerializeHelper.DESerializer<List<Student>>(strXML);
