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);
View Code

2. Xml转换到实体对象

1 Student stu2 = XmlUtil.Deserialize(typeof(Student), xml) as Student;
2 Console.Write(string.Format("名字:{0},年龄:{1}", stu2.Name, stu2.Age));
View Code

 

3. DataTable转换到Xml

 1 // 生成DataTable对象用于测试
 2 DataTable dt1 = new DataTable("mytable");   // 必须指明DataTable名称
 3  
 4 dt1.Columns.Add("Dosage", typeof(int));
 5 dt1.Columns.Add("Drug", typeof(string));
 6 dt1.Columns.Add("Patient", typeof(string));
 7 dt1.Columns.Add("Date", typeof(DateTime));
 8  
 9 // 添加行
10 dt1.Rows.Add(25, "Indocin", "David", DateTime.Now);
11 dt1.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
12 dt1.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
13 dt1.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
14 dt1.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);
15  
16 // 序列化
17 xml = XmlUtil.Serializer(typeof(DataTable), dt1);
18 Console.Write(xml);
View Code

 

4. Xml转换到DataTable

 1 // 反序列化
 2 DataTable dt2 = XmlUtil.Deserialize(typeof(DataTable), xml) as DataTable;
 3  
 4 // 输出测试结果
 5 foreach (DataRow dr in dt2.Rows)
 6 {
 7     foreach (DataColumn col in dt2.Columns)
 8     {
 9         Console.Write(dr[col].ToString() + " ");
10     }
11  
12     Console.Write("\r\n");
13 }
View Code

 

5. List转换到Xml

1 // 生成List对象用于测试
2 List<Student> list1 = new List<Student>(3);
3  
4 list1.Add(new Student() { Name = "okbase", Age = 10 });
5 list1.Add(new Student() { Name = "csdn", Age = 15 });
6 // 序列化
7 xml = XmlUtil.Serializer(typeof(List<Student>), list1);
8 Console.Write(xml);
View Code

 

6. Xml转换到List

1 List<Student> list2 = XmlUtil.Deserialize(typeof(List<Student>), xml) as List<Student>;
2 foreach (Student stu in list2)
3 {
4     Console.WriteLine(stu.Name + "," + stu.Age.ToString());
5 }
