Serialization of lists in C#classes

Good afternoon guys, I’m running an Nfe project for emission, so I opted, after searching use class serialization to mount xml. Everything works very well, from a class structure that defined the xml, but in a certain part I needed to implement lists in a part of the class to serialize, in Nfe tag det, where I add the note items, I assembled the class perfectly, it worked, the problem is that the tag as in the code below is not a list, and I don’t know how to instantiate it as a list,in my attempts it didn’t work, however your Childs are all lists.

the tag has to be mounted dynamically, ex:

< det nItem="1" > ......other tags..... < /det > < det nItem="2" > ......other tags..... < /det > and so on.**

public class NFe

    public infNFe infNFe;

CLASSE INSTANCIADA PARA SERIALIZAR

I used a repeat loop in the instances below 

for(int item = 0; item <= 2 ;item++){  
    nfe.infNFe.det = new det();
                   nfe.infNFe.det.nItem = item.ToString();
                   nfe.infNFe.det.prod.Add(new prod(item.ToString(), "SASASASA", "sasasa", "SASASASASAS", "SSASASASA", "SASASASAS", "SASASASAS", "SASASASAS", "SASASASA", "SASASASAS", "SASASASASA", "SASASASASAS", "SASASASA", "SASASASAS", "SASASASA", "SASASASAS", "SASASASASA", "SASASASA", "SAS", "SASASAS"));
                   nfe.infNFe.det.imposto = new imposto();
                   nfe.infNFe.det.imposto.vTotTrib = "BLA BLA BLA BLA BLA";
                   nfe.infNFe.det.imposto.ICSM = new ICMS();
                   nfe.infNFe.det.imposto.ICSM.ICMS00.Add(new ICMS00("SASASASASASA", "SASASASASAS", "SASASASAS", "SASASASASA", "SASASASAS", "ASASASASA"));
                   nfe.infNFe.det.imposto.IPI = new IPI();
                   nfe.infNFe.det.imposto.IPI.cEnq = "SASASASA";
                   nfe.infNFe.det.imposto.IPI.IPINT.Add(new IPINT(""));
                   nfe.infNFe.det.imposto.PIS = new PIS();
                   nfe.infNFe.det.imposto.PIS.PISAliq.Add(new PISAliq("SASASASASA", "SASASASASA", "SASASASASA", "SASASASASA"));
                   nfe.infNFe.det.imposto.PIS.PISOutr.Add(new PISOutr("ASASASASASA", "ASASASASASA", "ASASASASASA", "SASASASASA"));
                   nfe.infNFe.det.imposto.COFINS = new COFINS();
                   nfe.infNFe.det.imposto.COFINS.COFINSAliq.Add(new COFINSAliq("SASASASA", "SASASASA", "SASASASA", "SASASASAS"));
                   nfe.infNFe.det.imposto.COFINS.COFINSOutr.Add(new COFINSOutr("SASASASAS", "ASASASASAS", "SASASASA", "SASASASA"));

}

But the result of serialization of the lists is only the last iteration in the for loop.

Remembering that I am Creating the Nfe class in its entirety.

if I try to serialize only the class works.

Summarizing how I transform the class into a list and instantiate it, and your Childs are also lists.

Try this way

public sealed class NFe
{
    public infNFe infNFe;
}

public sealed class infNFe
{
    private List<det> _dets;
    public det[] det { 
         get { return _dets.toArray(); } //pegamos a variável privada que é uma lista e convertemos ela para array na hora de serializar (ou quando se acessa esta propriedade - det)
         set { _dets = value.toList(); } //supondo que você receba um array de dets, convertemos ele para lista e armazenamos na variável privada.
    }
    //Se você utilizar lista provavelmente terá problemas na serialização XML, dependendo de como esta sendo feita essa serialização, então vamos usar um array primitivo.

    public infNFe(){
       _dets = new List<det>();
    }

    public Add(det det)
    {
       _dets.add(det);
    }
}

There in your loop, do the following:

 nfe.infNFe = new infNfe();
 for(int item = 0; item <= 2 ;item++){  
    var atual = new det();
    atual.nItem = item.ToString();
    atual.nItem.prod.Add(new prod(item.ToString(), "SASASASA", "sasasa", "SASASASASAS", "SSASASASA", "SASASASAS", "SASASASAS", "SASASASAS", "SASASASA", "SASASASAS", "SASASASASA", "SASASASASAS", "SASASASA", "SASASASAS", "SASASASA", "SASASASAS", "SASASASASA", "SASASASA", "SAS", "SASASAS"));
    atual.nItem.imposto = new imposto();
    atual.nItem.imposto.vTotTrib = "BLA BLA BLA BLA BLA";
    atual.nItem.imposto.ICSM = new ICMS();
    atual.nItem.imposto.ICSM.ICMS00.Add(new ICMS00("SASASASASASA", "SASASASASAS", "SASASASAS", "SASASASASA", "SASASASAS", "ASASASASA"));
    atual.nItem.imposto.IPI = new IPI();
    atual.nItem.imposto.IPI.cEnq = "SASASASA";
    atual.nItem.imposto.IPI.IPINT.Add(new IPINT(""));
    atual.nItem.imposto.PIS = new PIS();
    atual.nItem.imposto.PIS.PISAliq.Add(new PISAliq("SASASASASA", "SASASASASA", "SASASASASA", "SASASASASA"));
    atual.nItem.imposto.PIS.PISOutr.Add(new PISOutr("ASASASASASA", "ASASASASASA", "ASASASASASA", "SASASASASA"));
    atual.nItem.imposto.COFINS = new COFINS();
    atual.nItem.imposto.COFINS.COFINSAliq.Add(new COFINSAliq("SASASASA", "SASASASA", "SASASASA", "SASASASAS"));
    atual.nItem.imposto.COFINS.COFINSOutr.Add(new COFINSOutr("SASASASAS", "ASASASASAS", "SASASASA", "SASASASA"));


    //aqui está a mágica
    nfe.infNFe.add(atual); //aqui você usa o método add da class infNfe que criamos previamente e com isso teremos a lista de "det"s populada
}

    Guilherme, it worked perfectly well, leave the array and then add a list, I only changed a few things [Xmlelement("det")] public List<det> Dets; public infNFe() { Dets = new List<det>(); } public void add(det det){ Dets. Add(det); }, I removed the instance nfe.infNFe = new infNfe();, because at the beginning of Cod I had already instantiated, and removed nItem, set up Nfe directly with the items dynamically, thank you very much for the help, I have to get the database data now vlw.
