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

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對象用於測試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); |

//
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

//

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());} |
從代碼可以看到，千變萬化不離其宗!
public class XmlSerialize<T>
{
/// <summary
/// 對象序列化成 XML String
/// </summary
public static string XmlSerialize<T>(T obj)
{
string xmlString = string.Empty;
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
using (MemoryStream ms = new MemoryStream())
{
xmlSerializer.Serialize(ms, obj);
xmlString = Encoding.UTF8.GetString(ms.ToArray());
}
return xmlString;
}
/// <summary
/// XML String 反序列化成對象
/// </summary
public static T XmlDeserialize<T>(string xmlString)
{
T t = default(T);
XmlSerializer xmlSerializer = new XmlSerializer(typeof(T));
using (Stream xmlStream = new MemoryStream(Encoding.UTF8.GetBytes(xmlString)))
{
using (XmlReader xmlReader = XmlReader.Create(xmlStream))
{
Object obj = xmlSerializer.Deserialize(xmlReader);
t = (T)obj;
}
} return t;
}
//如果要序列化到一個文件，則使用FileStream就可以瞭如：
// string strFile = @c:/book.xml;
//using (FileStream fs = new FileStream(strFile, FileMode.Create)){
//XmlSerializer formatter = new XmlSerializer(typeof(T));
//formatter.Serialize(fs, entity);}附：其實還可以直接用SringWriter
//StringBuilder sb = new StringBuilder();
//System.IO.StringWriter writer = new System.IO.StringWriter(sb)
}
