C#怎么實現(xiàn)實體類和XML的相互轉(zhuǎn)換

這篇文章主要為大家展示了“C#怎么實現(xiàn)實體類和XML的相互轉(zhuǎn)換”，內(nèi)容簡而易懂，條理清晰，希望能夠幫助大家解決疑惑，下面讓小編帶領(lǐng)大家一起研究并學(xué)習(xí)一下“C#怎么實現(xiàn)實體類和XML的相互轉(zhuǎn)換”這篇文章吧。

一、實體類轉(zhuǎn)換成XML

將實體類轉(zhuǎn)換成XML需要使用XmlSerializer類的Serialize方法，將實體類序列化

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、定義實體類

[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、給實體類賦值，并通過序列化將實體類轉(zhuǎn)換成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 = "測試";
            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實例

<?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>測試</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、將XML轉(zhuǎn)換成實體類

把XML轉(zhuǎn)換成相應(yīng)的實體類，需要使用到XmlSerializer類的Deserialize方法，將XML進行反序列化。

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：

將上例中序列化后的XML反序列化成實體類

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

 三、將DataTable轉(zhuǎn)換成XML

//將DataTable轉(zhuǎn)換成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, "小紅", '2');
dt.Rows.Add(3, "小王", '2');
dt.Rows.Add(4, "測試", '2');
//序列化，將DataTable轉(zhuǎn)換成XML格式的字符串
string strXML = XmlSerializeHelper.XmlSerialize <DataTable> (dt);

四、將XML轉(zhuǎn)換成DataTable

//反序列化，將XML轉(zhuǎn)換成字符串
DataTable dtNew=  XmlSerializeHelper.DESerializer<DataTable>(strXML);

五、將List集合轉(zhuǎn)換成XML

/// <summary>
/// 測試類
/// </summary>
public class Student
{
    public int Id { get; set; }
    public string Name { get; set; }
    public char Sex { get; set; }
    public int Age { get; set; }
}

//測試集合
List<Student> list = new List<Student>()
{
        new Student(){Id=1,Name="小紅",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="測試",Sex='2',Age=23}
};
//序列化
string strXML = XmlSerializeHelper.XmlSerialize<List<Student>>(list);

六、將XML轉(zhuǎn)換成集合

使用上面例子中集合轉(zhuǎn)換成的XML進行反序列化。

//反序列化
List<Student> listStu = XmlSerializeHelper.DESerializer<List<Student>>(strXML);
