我們需要在XML與實體類，DataTable，List之間進行轉換，下面是XmlUtil類，該類來自網絡并稍加修改。

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序列化與反序列化 /// </summary> public class XmlUtil {#region 反序列化/// <summary>/// 反序列化/// </summary>/// <param name="type">類型</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">類型</param>/// <param name="obj">對象</param>/// <returns></returns>public static string Serializer(Type type, object obj){MemoryStream Stream = new MemoryStream();XmlSerializer xml = new XmlSerializer(type);try{//序列化對象 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 }

下面是測試代碼：

?
1. 實體對象轉換到Xml

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);

?

2. Xml轉換到實體對象

Student stu2 = XmlUtil.Deserialize(typeof(Student), xml) as Student; Console.Write(string.Format("名字:{0},年齡:{1}", stu2.Name, stu2.Age));

?

3. DataTable轉換到Xml

?

// 生成DataTable對象用于測試 DataTable dt1 = new DataTable("mytable"); // 必須指明DataTable名稱 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);

?

4. Xml轉換到DataTable

?

// 反序列化 DataTable dt2 = XmlUtil.Deserialize(typeof(DataTable), xml) as DataTable;// 輸出測試結果 foreach (DataRow dr in dt2.Rows) {foreach (DataColumn col in dt2.Columns){Console.Write(dr[col].ToString() + " ");}Console.Write("\r\n"); }

?

5. List轉換到Xml

// 生成List對象用于測試 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);

?

6. Xml轉換到List

List<Student> list2 = XmlUtil.Deserialize(typeof(List<Student>), xml) as List<Student>; foreach (Student stu in list2) {Console.WriteLine(stu.Name + "," + stu.Age.ToString()); }
