Wrong XML string based on XSD c#

Question

I am new in programming and especially in XML and XSD and I want help.

I have an XSD file which you can find here InvoicesDoc-v0.5.xsd

I convert it with Xsd2Code and with command

xsd InvoicesDoc-v0.5.xsd /classes

into classes and I try to create an XML string based on that XSD. My code for creating the XML is

 public partial class MyDataOperations
    {
        private Timologio TimologioCurrent { get; set; }
        private StringBuilder ErrorBuilder { get; set; }
        private AadeBookInvoiceType aadeBookInvoiceType { get; set; }
        private InvoicesDoc invoicesDoc { get; set; }

      public MyDataOperations(Timologio timologio)
        {
            TimologioCurrent = timologio;
            invoicesDoc = new InvoicesDoc();
            LengthWarn.WarnBuilder = new StringBuilder();

        }

        public void Create()
        {
            Header();
            Ekdotis();
            Paraliptis();
            Epikefalida();
            Grammes();
            Perilipsi();

        }

        void Header()
        {
            aadeBookInvoiceType= new AadeBookInvoiceType(); 
        }
        void Ekdotis()
        {
            PartyType partyType = new PartyType();
            partyType.vatNumber = TimologioCurrent.Diasafistis.Afm;
            partyType.country = CountryType.GR;
            aadeBookInvoiceType.issuer = partyType;
        }
        void Paraliptis()
        {
            PartyType partyType = new PartyType();
            partyType.vatNumber = TimologioCurrent.Afm;
            partyType.country = CountryType.GR;
            aadeBookInvoiceType.counterpart = partyType;
        }
        void Epikefalida()
        {
            InvoiceHeaderType HeaderType = new InvoiceHeaderType();
            HeaderType.aa = '1';
            HeaderType.issueDate = DateTime.Today;


        }
        void Grammes()
        {
            InvoiceRowType rowType = new InvoiceRowType();
            rowType.lineNumber = '1';
            rowType.invoiceDetailTypeSpecified = true;
            rowType.invoiceDetailType = '1';
            InvoiceRowTypeNetValue value = new InvoiceRowTypeNetValue();
            value.Value = 200;
            rowType.vatCategory = 3;
        }
        void Perilipsi()
        {
            InvoiceSummaryType summaryType = new InvoiceSummaryType();
            summaryType.totalNetValue = 200;
            summaryType.totalVatAmount = 100;
            summaryType.totalWithheldAmount = 0;
            summaryType.totalFeesAmount = 0;
            summaryType.totalStampDutyAmount = 0;
            summaryType.totalOtherTaxesAmount = 0;
            summaryType.totalDeductionsAmount = 0;
            summaryType.totalGrossValue = 0;
        }

        public override string ToString()
        {
            return GetStringMessage();
        }

        public string GetStringMessage()
        {
            return aadeBookInvoiceType.Serialize();
        }
}

My problem is that When I create the XML string to send it it has the wrong format. The XML that I create has the following format

 <?xml version="1.0" encoding="utf-8"?>
<AadeBookInvoiceType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns="http://www.aade.gr/myDATA/invoice/v1.0">
    <issuer>
        <vatNumber>043529374</vatNumber>
        <country>GR</country>
        <address>Thessaloniki</address>
    </issuer>
    <counterpart>
        <vatNumber>094006956</vatNumber>
        <country>GR</country>
        <address>Thessaloniki</address>
    </counterpart>
    <invoiceHeader>
        <branch>0</branch>
        <aa>1</aa>
        <issueDate>2019-08-05</issueDate>
        <invoiceType>1.1</invoiceType>
        <currency>EUR</currency>
    </invoiceHeader>
    <invoiceSummary>
        <totalNetValue>0</totalNetValue>
        <totalVatAmount>0</totalVatAmount>
        <totalWithheldAmount>0</totalWithheldAmount>
        <totalFeesAmount>0</totalFeesAmount>
        <totalStampDutyAmount>0</totalStampDutyAmount>
        <totalOtherTaxesAmount>0</totalOtherTaxesAmount>
        <totalDeductionsAmount>0</totalDeductionsAmount>
        <totalGrossValue>0</totalGrossValue>
    </invoiceSummary>
</AadeBookInvoiceType>

and I want to have an output with the following format

    <?xml version="1.0" encoding="utf-8"?>
<InvoicesDoc xmlns="http://www.aade.gr/myDATA/invoice/v1.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.aade.gr/myDATA/invoice/v1.0">
    <invoice>
        <issuer>
            <vatNumber>#####</vatNumber>
            <country>GR</country>
        </issuer>
        <counterpart>
            <vatNumber>####</vatNumber>
            <country>GR</country>
            <name>string</name>
        </counterpart>
        <invoiceHeader>

            <vatPaymentSuspension>true</vatPaymentSuspension>

            <netValue>5.00</netValue>
            <vatCategory>1</vatCategory>
            <vatExemptionCategory>2</vatExemptionCategory>
            <discountOption>0</discountOption>
            <withheldPercentCategory>10</withheldPercentCategory>
            <feesAmount>0.00</feesAmount>
            <feesPercentCategory>4</feesPercentCategory>
            <otherTaxesPercentCategory>5</otherTaxesPercentCategory>
        </invoiceDetails>
        <invoiceSummary>
            <totalNetValue>5.00</totalNetValue>
            <totalVatAmount>0.00</totalVatAmount>
            <totalWithheldAmount>0.00</totalWithheldAmount>
            <totalFeesAmount>0.00</totalFeesAmount>
            <totalStampDutyAmount>0.00</totalStampDutyAmount>
            <totalOtherTaxesAmount>0.00</totalOtherTaxesAmount>
            <totalDeductionsAmount>0.00</totalDeductionsAmount>
            <totalGrossValue>5.00</totalGrossValue>
        </invoiceSummary>
    </invoice>
</InvoicesDoc>

I don't know if I am doing something wrong with the convertion from XSD to XML or with my code in c#. I can't upload the final cs file that is created by the tools because it is too big.

You need to serialize InvoicesDoc and then change the classes to look like code below :

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

namespace ConsoleApplication1
{
    class Program
    {
        const string FILENAME = @"c:\temp\test.xml";
        static void Main(string[] args)
        {
            XmlWriterSettings settings = new XmlWriterSettings();
            settings.Indent = true;
            XmlWriter writer = XmlWriter.Create(FILENAME, settings);

            XmlSerializer serializer = new XmlSerializer(typeof(InvoicesDoc));

            InvoicesDoc doc = new InvoicesDoc()
            {
                invoice = new AadeBookInvoiceType[] {
                    new AadeBookInvoiceType() 
                    {

                    }
                }
            };

            serializer.Serialize(writer, doc);
        }
    }
    public class InvoicesDoc
    {
        [XmlElement(ElementName = "invoice")]
        public AadeBookInvoiceType[] invoice { get; set; }
    }
    [XmlRoot(ElementName = "invoice")]
    public class AadeBookInvoiceType
    {
        //add the rest of the invoice properties here
    }
}
