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); |

// 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("

} |
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 = "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转换到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());
} |
从代码可以看到，千变万化不离其宗!
