How to Write Object Data to an XML File using C#

Write Object Data to an XML File using C# 

This example writes the object from a class to an XML file using the XmlSerializer class.This code example defines a class named Book, creates an instance of the class, and uses XML serialization

to write the instance to an XML file.

Example:-

public class XMLWrite

{

         static void Main(string[] args)

           {

                  WriteXML();

            }

               public class Book

               {

                    public String title {get; set; };

                }

                

                 public static void WriteXML()

                {

                    Book overview = new Book();

                    overview.title = "Serialization Overview";

                    System.Xml.Serialization.XmlSerializer writer =

                       new System.Xml.Serialization.XmlSerializer(typeof(Book));

                   System.IO.StreamWriter file = new System.IO.StreamWriter(

                                      @"c:\temp\SerializationOverview.xml");

                   writer.Serialize(file, overview);

                   file.Close();

                }

}

Security

This example creates a new file, if the file does not already exist. If an application needs to create a file, that application needs Create access for the folder. If the file already exists, the application needs only Write access, a lesser privilege. Where possible, it is more secure to create the file during deployment, and only grant Read access to a single file, rather than Create access for a folder.
