?
1. 實體對象轉換到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轉換到實體對象
?
| 1 2 | Student stu2 = XmlUtil.Deserialize(typeof(Student), xml)?as?Student; Console.Write(string.Format("名字:{0},年齡:{1}", stu2.Name, stu2.Age)); |
3.?DataTable轉換到Xml
?
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | // 生成DataTable對象用于測試DataTable dt1 =?new?DataTable("mytable");???// 必須指明DataTable名稱 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轉換到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; // 輸出測試結果foreach?(DataRow dr?in?dt2.Rows) {????foreach?(DataColumn col?in?dt2.Columns) ????{ ????????Console.Write(dr[col].ToString() +?" "); ????} ????Console.Write("\r\n"); } |
5.?List轉換到Xml
?
| 1 2 3 4 5 6 7 8 | // 生成List對象用于測試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轉換到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()); } |
