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
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
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));
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);
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 }
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);
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 }
