下面是测试代码：

 

1. 实体对象转换到Xml

 

1 public class Student
2 {
3     public string Name { set; get; }
4     public int Age { set; get; }
5 }
6  
7 Student stu1 = new Student() { Name = "okbase", Age = 10 };
8 string xml = XmlUtil.Serializer(typeof(Student), stu1);
9 Console.Write(xml);

2. Xml转换到实体对象

3. DataTable转换到Xml

4. Xml转换到DataTable

下面是测试代码：

 

1. 实体对象转换到Xml

 

1 2 3 4 5 6 7 8 9

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

 

1 2	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

 

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

// 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);

4. Xml转换到DataTable

 

1 2 3 4 5 6 7 8 9 10 11 12 13

// 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

 

1 2 3 4 5 6 7 8

// 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

 

1 2 3 4 5

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