C#实现XML与实体类之间相互转换的方法(序列化与反序列化)

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;
/// 

/// Xml序列化与反序列化
/// 
public class XmlUtil
{
  #region 反序列化
  /// 

  /// 反序列化
  /// 
  /// 类型
  /// XML字符串
  /// 
  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;
    }
  }
  /// 

  /// 反序列化
  /// 
  /// 
  /// 
  /// 
  public static object Deserialize(Type type, Stream stream)
  {
    XmlSerializer xmldes = new XmlSerializer(type);
    return xmldes.Deserialize(stream);
  }
  #endregion
  #region 序列化
  /// 

  /// 序列化
  /// 
  /// 类型
  /// 对象
  /// 
  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);

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("rn");
}

// 生成List对象用于测试
List list1 = new List(3);

// 序列化

Console.Write(xml);

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

  XmlNodeList macthNodes = root.SelectNodes("//ab:Identifiers/ab:MarketplaceASIN", nsmgr);
