本文实例讲述了C#实现XML与实体类之间相互转换的方法。分享给大家供大家参考，具体如下：

using System;using System.Collections.Generic;using System.Linq;using System.Text;using System.IO;using System.Data;using System.Xml;using System.Xml.Serialization;/// <summary>/// Xml序列化与反序列化/// </summary>public class XmlUtil{ #region 反序列化 /// <summary> /// 反序列化 /// </summary> /// <param name="type">类型</param> /// <param name="xml">XML字符串</param> /// <returns></returns> public static object Deserialize(Type type, string xml) { try { using (StringReader sr = new StringReader(xml)) { XmlSerializer xmldes = new XmlSerializer(type); return xmldes.Deserialize(sr); } } catch (Exception e) { return null; } } /// <summary> /// 反序列化 /// </summary> /// <param name="type"></param> /// <param name="xml"></param> /// <returns></returns> public static object Deserialize(Type type, Stream stream) { XmlSerializer xmldes = new XmlSerializer(type); return xmldes.Deserialize(stream); } #endregion #region 序列化 /// <summary> /// 序列化 /// </summary> /// <param name="type">类型</param> /// <param name="obj">对象</param> /// <returns></returns> public static string Serializer(Type type, object obj) { MemoryStream Stream = new MemoryStream(); XmlSerializer xml = new XmlSerializer(type); try { //序列化对象 xml.Serialize(Stream, obj); } catch (InvalidOperationException) { throw; } Stream.Position = 0; StreamReader sr = new StreamReader(Stream); string str = sr.ReadToEnd(); sr.Dispose(); Stream.Dispose(); return str; } #endregion}public class Student{ public string Name { set; get; } public int Age { set; get; }}Student stu1 = new Student() { Name = "okbase", Age = 10 };string xml = XmlUtil.Serializer(typeof(Student), stu1);Console.Write(xml);Student stu2 = XmlUtil.Deserialize(typeof(Student), xml) as Student;Console.Write(string.Format("名字:{0},年龄:{1}", stu2.Name, stu2.Age));// 生成DataTable对象用于测试DataTable dt1 = new DataTable("mytable"); // 必须指明DataTable名称dt1.Columns.Add("Dosage", typeof(int));dt1.Columns.Add("Drug", typeof(string));dt1.Columns.Add("Patient", typeof(string));dt1.Columns.Add("Date", typeof(DateTime));// 添加行dt1.Rows.Add(25, "Indocin", "David", DateTime.Now);dt1.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);dt1.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);dt1.Rows.Add(21, "Combivent", "Janet", DateTime.Now);dt1.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);// 序列化xml = XmlUtil.Serializer(typeof(DataTable), dt1);Console.Write(xml);// 反序列化DataTable dt2 = XmlUtil.Deserialize(typeof(DataTable), xml) as DataTable;// 输出测试结果foreach (DataRow dr in dt2.Rows){ foreach (DataColumn col in dt2.Columns) { Console.Write(dr[col].ToString() + " "); } Console.Write("\r\n");}// 生成List对象用于测试List<Student> list1 = new List<Student>(3);list1.Add(new Student() { Name = "okbase", Age = 10 });list1.Add(new Student() { Name = "csdn", Age = 15 });// 序列化xml = XmlUtil.Serializer(typeof(List<Student>), list1);Console.Write(xml);List<Student> list2 = XmlUtil.Deserialize(typeof(List<Student>), xml) as List<Student>;foreach (Student stu in list2){ Console.WriteLine(stu.Name + "," + stu.Age.ToString());}protected void Page_Load(object sender, EventArgs e){ string strTest = @"<Relationships> <VariationParent xmlns='http:///schema/Products/2011-10-01\"", ""); return xml;}
