C# XML parsing error with an array of objects

Question

I have a simple XML file with an array of objects:

<?xml version="1.0" encoding="UTF-8"?>
<complexes>
    <complex>
        <name>NAME1</name>
    </complex>
</complexes>

So I've made a class structure to suit it:

public complex[] complexes;

public class complex
{
    public string name;
}

And I do parsing with the standard C# tools:

XmlSerializer reader = new XmlSerializer(typeof(complex[]));
StreamReader file = new StreamReader("test.xml");
complexes = (complex[])reader.Deserialize(file);

For some reason I get an exception on the last line:

System.InvalidOperationException: 'There is an error in XML document (2, 2).'
InvalidOperationException: <complexes xmlns=''> was not expected.

What's the issue?

@iSR5 I have no issues parsing an object (which is an issue for the post you've mentioned). I only get an error while going with the array. — JustLogin, Jul 16 '22 at 17:06

Following works :

using System;
using System.Linq;
using System.Text;
using System.Collections;
using System.Collections.Generic;
using System.Xml;
using System.Xml.Serialization;


namespace ConsoleApp2
{
    class Program
    {

        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlSerializer serializer = new XmlSerializer(typeof(complexes));
            XmlReader reader = XmlReader.Create(FILENAME);
            complexes complexes = (complexes)serializer.Deserialize(reader);

        }

    }
    public class complexes
    {
        [XmlElement("complex")]
        public complex[] complex { get; set; }
    }
    public class complex
    {
        public string name { get; set; }
    }


}
