2      b        321       b@b.com
3              


        

Answer 1

1) Create class called student

[Serializable]
public class Student
{
  public int ID { get; set; }
  public string Name { get; set; }
  public int Number { get; set; }
  public string Email { get; set; }
}

2) Get data into List called StudentListfrom Database

3)Then open or create xml file and add values

using (XmlWriter writer = XmlWriter.Create("Student.xml"))
{
    writer.WriteStartDocument();
    writer.WriteStartElement("Students");

    foreach (Student student in StudentList)
    {
    writer.WriteStartElement("Student");

    writer.WriteElementString("id", student.ID.ToString());
    writer.WriteElementString("name", student.Name.ToString());
    writer.WriteElementString("number", student.Number.ToString());
    writer.WriteElementString("email", student.Email.ToString());

    writer.WriteEndElement();
    }

    writer.WriteEndElement();
    writer.WriteEndDocument();
}
