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：
[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; }
}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);
<?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>
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);
//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);//反序列化，将XML转换成字符串 DataTable dtNew= XmlSerializeHelper.DESerializer<DataTable>(strXML);
/// <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);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);
