I have a SVG file in XML format i am trying to deserialize XML to C# objects but when trying to deserialize XML data it is giving error

Below is my code

XmlSerializer serializer = new XmlSerializer(typeof(List<rootobject>));
object objectList = null;
using (StreamReader stream = new StreamReader(@"C:\Users\sana-user\Documents\Visual Studio 2015\Projects\SVGXMLToJsonApp\SVGXMLToJsonApp\File\3rect.svg"))
{
objectList = serializer.Deserialize(stream);
}
Console.WriteLine(objectList);

Why convert a .svg file to json or even c# objects?

Member 13041059 4-Oct-18 6:41am

Want to insert json data in database and the data will be coming through .svg file only in my project

F-ES Sitecore 4-Oct-18 6:42am

Just deserialise the XML to your c# objects direct, going via json is pointless.

Maciej Los 10-Oct-18 13:26pm

There's something wrong with your xml. xsd.exe tool can not create a schema file for this. Please, try it by yourself: How to: Use the XML Schema Definition Tool to Generate Classes and XML Schema Documents

Solution 1

Your XML is the following:

<svg version="1.1" id="_x30_" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 1366 768" style="enable-background:new 0 0 1366 768;" xml:space="preserve">

<style type="text/css">

You have the following in your class:

public class Svg
...
public Style style { get; set; }
...
public class Style
...

You have two different versions of "style" in your XML, but only one version in your C#.

This is correct, it captures the style tag:

public class Style

public Style style { get; set; }

To capture the attribute you should add this to the Svg class:

public string style { get; set; }

Hope that helps!

When i added public string style { get; set; } it is giving error on same line
var obj = JsonConvert.DeserializeObject<rootobject>(jsondata);

{"Unexpected character encountered while parsing value: {. Path 'svg.style', line 9, position 12."}

Below is my SVG class

public class Svg
{
public string version { get; set; }
public string id { get; set; }
public string xmlns { get; set; }
public string __invalid_name__xmlnsxlink { get; set; }
public string x { get; set; }
public string y { get; set; }
public string viewBox { get; set; }
public Style style1 { get; set; }
public string style { get; set; }
public string __invalid_name__xmlspace { get; set; }
public List<string> significantwhitespace { get; set; }
public List<g> g { get; set; }
}

You should output the JSON data in the meantime so we can see what it looks like after the XML to JSON conversion.
