generate xml files based on my c# classes

Question

i have xml file that i need to update each and every time as per new client requirement. most of the time xml is not proper because of manual updation of xml file. I am thinking to write a program (web/windows) where proper validation is provided. and based on the input from ui I will going to create xml file. below is my sample xml file.

<community>
  <author>xxx xxx</author>
  <communityid>000</communityid>
  <name>name of the community</name>

<addresses>
        <registeredaddress>
          <addressline1>xxx</addressline1>
          <addressline2>xxx</addressline2>
          <addressline3>xxx</addressline3>
          <city>xxx</city>
          <county>xx</county>
          <postcode>0000-000</postcode>
          <country>xxx</country>
        </registeredaddress>
        <tradingaddress>
          <addressline1>xxx</addressline1>
          <addressline2>xxx</addressline2>
          <addressline3>xxx</addressline3>
          <city>xxx</city>
          <county>xx</county>
          <postcode>0000-000</postcode>
          <country>xxx</country>
        </tradingaddress>
      </addresses>


<community>

Create following classes to hold your data and validate it:

public class Community
{
    public string Author { get; set; }
    public int CommunityId { get; set; }
    public string Name { get; set; }
    [XmlArray]
    [XmlArrayItem(typeof(RegisteredAddress))]
    [XmlArrayItem(typeof(TradingAddress))]
    public List<Address> Addresses { get; set; }
}

public class Address
{
    private string _postCode;

    public string AddressLine1 { get; set; }
    public string AddressLine2 { get; set; }
    public string AddressLine3 { get; set; }
    public string City { get; set; }
    public string Country { get; set; }

    public string PostCode
    {
        get { return _postCode; }
        set {
            // validate post code e.g. with RegEx
            _postCode = value; 
        }
    }
}

public class RegisteredAddress : Address { }
public class TradingAddress : Address { }

And serialize that instance of community class to xml:

Community community = new Community {
    Author = "xxx xxx",
    CommunityId = 0,
    Name = "name of community",
    Addresses = new List<Address> {
        new RegisteredAddress {
            AddressLine1 = "xxx",
            AddressLine2 = "xxx",
            AddressLine3 = "xxx",
            City = "xx",
            Country = "xxxx",
            PostCode = "0000-00"
        },
        new TradingAddress {
            AddressLine1 = "zz",
            AddressLine2 = "xxx"
        }
    }
};

XmlSerializer serializer = new XmlSerializer(typeof(Community));
serializer.Serialize(File.Create("file.xml"), community);

I think a little googling will help you to understand how to deserialize community object back from file.

xml tags in xml are same as in cs files. how can i make to smaller case as in my original xml file. — Prashant, Feb 19 '13 at 09:26
@Prashant use `XmlElement` attributes. Like this `[XmlElement("name")] public string Name { get; set; }` also you will need `XmlRoot` attribute for community class. — Sergey Berezovskiy, Feb 19 '13 at 09:29
Can you specify the namespace of `XmlSerializer`, would've spared the google search. — Emy Blacksmith, Mar 29 '19 at 09:42

This is an old topic, but I wanted to give my own share. The xml you provided above is not valid, so I am using xml below as an example.

First, structure your xml how you want it to look like. Let's say it is going to look like this:

<note>
      <to>Tove</to>
      <from>Jani</from>
      <heading>Reminder</heading>
      <body>Don't forget me this weekend!</body>
</note>

Copy your xml code
Go to Visual Studio
Create a class file and clear the code in it
Then on the menu, click Edit\Paste Special\Paste Xml as Classes

Visual studio will generate the entire class.

Core/Standard 2.0.
/// <remarks/>
[System.SerializableAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)]
[System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]
public partial class note
{

    private string toField;

    private string fromField;

    private string headingField;

    private string bodyField;

    /// <remarks/>
    public string to
    {
        get
        {
            return this.toField;
        }
        set
        {
            this.toField = value;
        }
    }

    /// <remarks/>
    public string from
    {
        get
        {
            return this.fromField;
        }
        set
        {
            this.fromField = value;
        }
    }

    /// <remarks/>
    public string heading
    {
        get
        {
            return this.headingField;
        }
        set
        {
            this.headingField = value;
        }
    }

    /// <remarks/>
    public string body
    {
        get
        {
            return this.bodyField;
        }
        set
        {
            this.bodyField = value;
        }
    }
}
