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( "\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 = "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!
