Good serialization deserialization example in c# 4.0 (.Net 4.0)

Code of deserialization

           CarInfoCollection carInfoCollection = null;

            using (StringReader strReader = new StringReader(this.textBox.Text.Trim()))

            {

                using (XmlTextReader reader = new XmlTextReader(strReader))

                {

                    XmlSerializer serializer = new XmlSerializer(typeof(CarInfoCollection));

                    carInfoCollection = (CarInfoCollection)serializer.Deserialize(reader);

                    reader.Close();

                }

            }

            MessageBox.Show(carInfoCollection.CarInfoFields.Count().ToString());

Serialization Example

When we do not want xml declaration / omit xml declaration

OmitXmlDeclaration should be set to True while initializing XmlWriter. Sample :-

  public string SerializeToXML(T typeToSerialize)
        {
            using (var sw = new StringWriter())
            {
                using (var xw = XmlWriter.Create(sw, new XmlWriterSettings { OmitXmlDeclaration = true }))
                {
                    var serializer = new XmlSerializer(typeof(T));
                    
                    // below code will omit the namespace in serialized xml
                    XmlSerializerNamespaces ns = new XmlSerializerNamespaces();
                    ns.Add("", "");
                    serializer.Serialize(xw, typeToSerialize, ns, encodingStyle: string.Empty);
                }
                return sw.ToString();
            }
        }
