我们需要在XML与实体类，DataTable，List之间进行转换，下面是XmlUtil类，该类来自网络并稍加修改。

下面是测试代码：
1. 实体对象转换到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转换到实体对象
|

Student stu2 = XmlUtil.Deserialize(typeof(Student), xml) as
Student;Console.Write(string.Format("名字:{0},年龄:{1}", stu2.Name, stu2.Age)); |
3. DataTable转换到Xml

// 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); |

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");} |
5. List转换到Xml

// 生成List对象用于测试List<Student> list1 = new
List<Student>(3);list1.Add(new

Student() { Name = "csdn", Age = 15 });// 序列化xml = XmlUtil.Serializer(typeof(List<Student>), list1);Console.Write(xml); |
6. Xml转换到List

List<Student> list2 = XmlUtil.Deserialize(typeof(List<Student>), xml) as
List<Student>;foreach
(Student stu in

+ stu.Age.ToString());} |
从代码可以看到，千变万化不离其宗!
