[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); |

<?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); |

//将DataTable转换成XMLDataTable 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); |
四、将XML转换成DataTable
|

|
//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); |
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); |
