Implement XML serialization and deserialization through XmlSerializer

Through XmlSerializer, we can easily convert the Model and XML.

You can also set the Model feature to flexibly control serialization.

Using System. xml. serialization; using System. collections. generic; namespace Model {// <summary> // The node name is EleTeacher /// </summary> [Serializable] [XmlType ("EleTeacher")] public class Teacher {[XmlElement (ElementName = "user")] public string AuthorID {set; get;} [XmlIgnore] public string Content {set; get ;} [XmlText] public string Value {set; get;} [XmlArray ("students")] public List <Student> sds {set; get ;}} [Serializable] public class Student {[XmlAttribute (AttributeName = "id")] public string ID {set; get ;}[ XmlText] public string Name {set; get ;}}}Model

 

 

XmlSerializerDeserialize () for Xml deserialization ()

Send me the serialization and deserialization methods. You can replace the double quotation marks below the serialization:
# Region XML-related static methods
/// <Summary>
/// Use XmlSerializer to serialize an object
/// </Summary>
/// <Typeparam name = "T"> specifies the object type to be serialized. The [Serializable] feature must be declared. </typeparam>
/// <Param name = "obj"> object to be serialized </param>
Public static string XmlSerialize <T> (T obj)
{
Using (MemoryStream MS = new MemoryStream ())
{
XmlSerializer serializer = new XmlSerializer (typeof (T ));
Serializer. serialized (MS, obj );
Ms. Seek (0, SeekOrigin. Begin );
Using (StreamReader reader = new StreamReader (MS, Encoding. UTF8 ))
{
Return reader. ReadToEnd ();
}
}
}

/// <Summary>
/// Use XmlSerializer to deserialize an object
/// </Summary>
/// <Param name = "xmlOfObject"> xml string to be deserialized </param>
Public static T XmlDeserialize <T> (string xmlOfObject) where T: class
{
Using (MemoryStream MS = new MemoryStream ())
{
Using (StreamWriter sr = new StreamWriter (MS, Encoding. UTF8 ))
{
Sr. Write (xmlOfObject );
Sr. Flush ();
Ms. Seek (0, SeekOrigin. Begin );
XmlSerializer serializer = new XmlSerializer (typeof (T ));
Return serializer. Deserialize (MS) as T;
}

What are the problems with XmlSerializer serialization and deserialization?

[XmlRootAttribute ("Extensiondata", IsNullable = false)]
Public class Extensiondata
{
Public string MagnetPullStrength;
Public string MagnetGrade;
Public string VisibleCustomerID;
}

XmlSerializer serializer = new XmlSerializer (typeof (Extensiondata ));
TextWriter writer = new StreamWriter (CommonLogic. SafeMapPath ("images \ po. xml "));

Extensiondata po = new Extensiondata ();

Po. MagnetPullStrength = TextBox1.Text;
Po. MagnetGrade = TextBox2.Text;
Po. VisibleCustomerID = TextBox3.Text;

Serializer. Serialize (writer, po );

Writer. Close ();
