c# XML和實體類之間相互轉換(序列化和還原序列化)

標籤：

 

XML與實體類，DataTable，List之間進行轉換，下面是XmlUtil類，該類來自網路並稍加修改。

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序列化與還原序列化/// </summary>public class XmlUtil{    #region 還原序列化    /// <summary>    /// 還原序列化    /// </summary>    /// <param name="type">類型</param>    /// <param name="xml">XML字串</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>    /// 還原序列化    /// </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. 實體物件轉換到Xml

1 public class Student2 {3     public string Name { set; get; }4     public int Age { set; get; }5 }6  7 Student stu1 = new Student() { Name = "okbase", Age = 10 };8 string xml = XmlUtil.Serializer(typeof(Student), stu1);9 Console.Write(xml);

2. Xml轉換到實體物件

1 Student stu2 = XmlUtil.Deserialize(typeof(Student), xml) as Student;2 Console.Write(string.Format("名字:{0},年齡:{1}", stu2.Name, stu2.Age));

3. DataTable轉換到Xml

 1 // 產生DataTable對象用於測試 2 DataTable dt1 = new DataTable("mytable");   // 必須指明DataTable名稱 3   4 dt1.Columns.Add("Dosage", typeof(int)); 5 dt1.Columns.Add("Drug", typeof(string)); 6 dt1.Columns.Add("Patient", typeof(string)); 7 dt1.Columns.Add("Date", typeof(DateTime)); 8   9 // 添加行10 dt1.Rows.Add(25, "Indocin", "David", DateTime.Now);11 dt1.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);12 dt1.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);13 dt1.Rows.Add(21, "Combivent", "Janet", DateTime.Now);14 dt1.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);15  16 // 序列化17 xml = XmlUtil.Serializer(typeof(DataTable), dt1);18 Console.Write(xml);

4. Xml轉換到DataTable

 1 // 還原序列化 2 DataTable dt2 = XmlUtil.Deserialize(typeof(DataTable), xml) as DataTable; 3   4 // 輸出測試結果 5 foreach (DataRow dr in dt2.Rows) 6 { 7     foreach (DataColumn col in dt2.Columns) 8     { 9         Console.Write(dr[col].ToString() + " ");10     }11  12     Console.Write("\r\n");13 }

5. List轉換到Xml

1 // 產生List對象用於測試2 List<Student> list1 = new List<Student>(3);3  4 list1.Add(new Student() { Name = "okbase", Age = 10 });5 list1.Add(new Student() { Name = "csdn", Age = 15 });6 // 序列化7 xml = XmlUtil.Serializer(typeof(List<Student>), list1);8 Console.Write(xml);

6. Xml轉換到List

1 List<Student> list2 = XmlUtil.Deserialize(typeof(List<Student>), xml) as List<Student>;2 foreach (Student stu in list2)3 {4     Console.WriteLine(stu.Name + "," + stu.Age.ToString());5 }
