Question

My error is: Unable to cast object of type ‘System.Xml.Linq.XDocument’ to type

I’m trying to execute this code:

XmlSerializer s1 = new XmlSerializer(typeof(xdoc.toString()));

where xdoc has this value:

<root>
  <row1>
    <ing>john</ing>
  </row1>
  <row1>
    <ing>some name</ing>
  </row1>
  <row>
    <name>salad</name>
    <ID>8</ID>
  </row>
</root>

I created a class which like this:

class Print {
    List<row1> row1 = new List<row1>();
    List<row> row = new List<row>();
}

public class row1
{
    public string ing { get; set; }
}

public class row
{
    public string name { get; set; }       
    public string ID { get; set; }
}

But it doesn’t work. What am I doing wrong?

You don’t need XmlSerializer when you have XDocument. Linq is enough

List<row1> row1 = xDoc.Descendants("row1")
                .Select(x => new row1() { ing = x.Element("ing").Value })
                .ToList();

List<row> row = xDoc.Descendants("row")
                    .Select(x => new row() { 
                        name = x.Element("name").Value,
                        ID = x.Element("ID").Value 
                    })
                    .ToList();
