Convert class object to XML using C# in .NET

People is the class whose object needs to be converted in XML string which later can be stored in a DB field or as XML file.

    public class PersonDetail
    {
        public string FirstName { get; set; }
        public string LastName { get; set; }
    }
    public class People
    {
        public People()
        {
            PeopleList = new List<ProductImage>();
        }
        public List<PersonDetail> PeopleList{ get; set; }
    }

Function to convert class object to XML string:

public static string SerializeToXml<T>(T value)
     {
         StringWriter writer = new StringWriter(CultureInfo.InvariantCulture);
         XmlSerializer serializer = new XmlSerializer(typeof(T));
         serializer.Serialize(writer, value);
         return writer.ToString();
     }

C# code to convert class object to XML string:

People peopleDetailList = new People();
 PersonDetail pDetail = new PersonDetail ();
            pDetail.FirstName= "Vivek";
            pDetail.LastName= "Goyal";
            peopleDetailList.PeopleList.Add(pDetail);
            string XMLProductImageList = SerializeToXml(peopleDetailList);

Resultant XML string will be:

<?xml version="1.0" encoding="utf-16"?>
<People xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xmlns:xsd="http://www.w3.org/2001/XMLSchema">;
  <PeopleList>
    <PersonDetail>
      <FirstName>Vivek</FirstName>
      <LastName>Goyal</LastName>
    </PersonDetail>   
  </PeopleList>
</People>
