How can I turn an XML document into an easy to use C# object?

问题

The Distributed project "World Community Grid" has the ability to get detailed user information such as:

<?xml version="1.0" encoding="UTF-8"?>

I was able to get this XML by going here:

 http://www.worldcommunitygrid.org/verifyMember.do?name=makerofthings7&code=SECRET CODE HERE

Then extracting the secret code from this page which is unique on a per person basis.

Since this is such a good cause, I want to encourage other people to use this API and "compete" for a cure.

Question

How can I take this XML file and convert it into a C# class that can easily be used by consuming users?

回答1:

You can use XmlSerialzier....

XmlSerializer serializer = new XmlSerializer(typeof(MemberStatsWithTeamHistory));
var obj = serializer.Deserialize(File.OpenRead(fname)) as MemberStatsWithTeamHistory;

PS: It is not the same as @AydinAdn's answer. I changed, for example, MemberStatsByProjects definition to make it work

public class StatisticsTotals
{
    public string RunTime { get; set; }
    public string RunTimeRank { get; set; }
    public string Points { get; set; }
    public string PointsRank { get; set; }
    public string Results { get; set; }
    public string ResultsRank { get; set; }
}

public class StatisticsAverages
{
    public string RunTimePerDay { get; set; }
    public string RunTimePerResult { get; set; }
    public string PointsPerHourRunTime { get; set; }
    public string PointsPerDay { get; set; }
    public string PointsPerResult { get; set; }
    public string ResultsPerDay { get; set; }
}

public class Resource
{
    public string Url { get; set; }
    public string Description { get; set; }
}

public class MemberStat
{
    public string Name { get; set; }
    public string MemberId { get; set; }
    public string TeamId { get; set; }
    public string RegisterDate { get; set; }
    public string LastResult { get; set; }
    public string NumDevices { get; set; }
    public StatisticsTotals StatisticsTotals { get; set; }
    public StatisticsAverages StatisticsAverages { get; set; }
    public Resource Resource { get; set; }
}

public class MemberStats
{
    public MemberStat MemberStat { get; set; }
}

public class StatisticsTotals2
{
    public string RunTime { get; set; }
    public string Points { get; set; }
    public string Results { get; set; }
}

public class Team
{
    public string Name { get; set; }
    public string TeamId { get; set; }
    public string JoinDate { get; set; }
    public StatisticsTotals2 StatisticsTotals { get; set; }
}

public class TeamHistory
{
    public Team Team { get; set; }
}

public class Project
{
    public string ProjectName { get; set; }
    public string ProjectShortName { get; set; }
    public string RunTime { get; set; }
    public string Points { get; set; }
    public string Results { get; set; }
}

public class MemberStatsWithTeamHistory
{
    public MemberStats MemberStats { get; set; }
    public TeamHistory TeamHistory { get; set; }
    public List<Project> MemberStatsByProjects { get; set; }
}

I converted it from xml to json http://www.utilities-online.info/xmltojson/#.Uqi40eIa6So
And from json to csharp: http://json2csharp.com/
Hope that helps :)

    public string ResultsRank { get; set; }
}

{
    public string RunTimePerDay { get; set; }
    public string RunTimePerResult { get; set; }
    public string PointsPerHourRunTime { get; set; }
    public string PointsPerDay { get; set; }
    public string PointsPerResult { get; set; }
    public string ResultsPerDay { get; set; }
}

First I use xsd.exe to create the classes from the xml using an schema XSD. (xsd.exe). This will create a class. Then use Generics:

public class XmlSerializer<T>
    {
        /// <summary>
        /// Load a Xml File and Deserialize into and object         
        /// </summary>
        /// <param name="xml">Xml String</param>
        /// <returns>Object representing the xml. You should catch an InvalidCastException</returns>
        public T DeserializeXmlProductContent(String xml)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(T));

            T obj;
            using (StringReader reader = new StringReader(xml))
            {
                obj = (T)serializer.Deserialize(reader);
            }
            return obj;


        }
        /// <summary>
        /// Serialize an Object to a Xml String
        /// </summary>
        /// <param name="obj">Any Object</param>
        /// <returns>Xml String</returns>
        public String SerializeProductContentToXml(T obj)
        {

            XmlSerializer serializer = new XmlSerializer(obj.GetType());

            using (StringWriter writer = new StringWriter())
            {
                serializer.Serialize(writer, obj);

                return writer.ToString();
            }

        }
    }

copy the XML to clipboard, go to a C# class file, place your cursor where you want the classes to be pasted and then go to Edit->Paste Special->Paste XML as C# class and you're done.
