Question

How can I Convert this xml Records object into List<dp_donorsearch>. My current code is below but I want to find best way to do this..... any idea?

<result>
    <record>
        <field name="donor_id" id="donor_id" value="9879" />
        <field name="first_name" id="first_name" value="Trix5647" />
        <field name="last_name" id="last_name" value="Rabbit657" />
        <field name="email" id="email" value="test@asd..com" />
        <field name="business_phone" id="business_phone" value="" />
        <field name="mobile_phone" id="mobile_phone" value="" />
        <field name="home_phone" id="home_phone" value="" />
        <field name="address" id="address" value="Street S.W. " />
        <field name="address2" id="address2" value="" />
        <field name="city" id="city" value="Quaker" />
        <field name="state" id="state" value="PA" />
        <field name="zip" id="zip" value="1234" />
        <field name="country" id="country" value="USA" />
    </record>
</result>

C# Code

Here's how you deserialize it into your class structure

Reference xml namespace

 using System.Xml;
 using System.Xml.Serialization;

deserialize

        string input =
            "<result>\n" +
               "<record>" +
                   "<field name=\"donor_id\" id=\"donor_id\" value=\"9879\" />" +
                   "<field name=\"first_name\" id=\"first_name\" value=\"Trix5647\" />" +
                   "<field name=\"last_name\" id=\"last_name\" value=\"Rabbit657\" />" +
                   "<field name=\"email\" id=\"email\" value=\"test@asd..com\" />" +
                   "<field name=\"business_phone\" id=\"business_phone\" value=\"\" />" +
                   "<field name=\"mobile_phone\" id=\"mobile_phone\" value=\"\" />" +
                   "<field name=\"home_phone\" id=\"home_phone\" value=\"\" />" +
                   "<field name=\"address\" id=\"address\" value=\"Street S.W. \" />" +
                   "<field name=\"address2\" id=\"address2\" value=\"\" />" +
                   "<field name=\"city\" id=\"city\" value=\"Quaker\" />" +
                   "<field name=\"state\" id=\"state\" value=\"PA\" />" +
                   "<field name=\"zip\" id=\"zip\" value=\"1234\" />" +
                   "<field name=\"country\" id=\"country\" value=\"USA\" />" +
               "</record>" +
           "</result>";

        XmlSerializer serializer = new XmlSerializer(typeof(Result));
        Result result = serializer.Deserialize(new System.IO.StringReader(input)) as Result;

Class definition

[XmlRoot("result")]
public class Result
{
    [XmlElement("record")]
    public Record[] Records { get; set; }
}

public class Record
{
    [XmlElement("field")]
    public Field[] Fields { get; set; }
}

public class Field
{
    [XmlAttribute("name")]
    public string Name { get; set; }

    [XmlAttribute("id")]
    public string Id { get; set; }

    [XmlAttribute("value")]
    public string Value { get; set; }
}
