C # XML and entity classes convert to and from each other (serialization and deserialization)

XML is transformed between the entity class, Datatable,list, and the following is the Xmlutil class, which comes from the network and is slightly modified.

Here is the test code:

1. Converting entity objects to XML

1  Public classStudent2 {3      Public stringName {Set;Get; }4      Public intAge {Set;Get; }5 }6  7Student STU1 =NewStudent () {Name ="Okbase", age =Ten };8 stringXML = Xmlutil.serializer (typeof(Student), STU1);9Console.Write (XML);

2. Converting XML to entity objects

1 Student stu2 = xmlutil.deserialize (typeof as Student; 2 console.write (string. Format (" name: {0}, Age: {1}", STU2. Name, STU2. Age));

3. DataTable conversion to XML

1 //generate a DataTable object for testing2DataTable DT1 =NewDataTable ("mytable");//The DataTable name must be specified3  4Dt1. Columns.Add ("dosage",typeof(int));5Dt1. Columns.Add ("Drug",typeof(string));6Dt1. Columns.Add ("Patient",typeof(string));7Dt1. Columns.Add ("Date",typeof(DateTime));8  9 //Adding RowsTenDt1. Rows.Add ( -,"indocin","David", DateTime.Now); OneDt1. Rows.Add ( -,"Enebrel","Sam", DateTime.Now); ADt1. Rows.Add (Ten,"hydralazine","Christoff", DateTime.Now); -Dt1. Rows.Add ( +,"combivent","Janet", DateTime.Now); -Dt1. Rows.Add ( -,"Dilantin","Melanie", DateTime.Now); the   - //Serialization of -XML = Xmlutil.serializer (typeof(DataTable), DT1); -Console.Write (XML);

4. XML conversion to DataTable

1 //deserialization2DataTable DT2 = Xmlutil.deserialize (typeof(DataTable), XML) asDataTable;3  4 //Output Test Results5 foreach(DataRow DrinchDT2. Rows)6 {7     foreach(DataColumn ColinchDT2. Columns)8     {9Console.Write (Dr[col]. ToString () +" ");Ten     } One   AConsole.Write ("\ r \ n"); -}

5. list conversion to XML

1 //generate a list object for testing2List<student> List1 =NewList<student> (3);3  4List1. ADD (NewStudent () {Name ="Okbase", age =Ten });5List1. ADD (NewStudent () {Name ="csdn", age = the });6 //Serialization of7XML = Xmlutil.serializer (typeof(list<student>), list1);8Console.Write (XML);

6. Convert XML to List

1 list<student> list2 = xmlutil.deserialize (typeof as list<student>; 2 foreach inch list2) 3 {4     " , " + stu. Age.tostring ()); 5 }
