hi i've a complex class with generic list and i need to check difference from two classes

this is is my class

public partial class Contatto

{



    [DataMember]

    public int? Id { get; set; }



    private int? tyContatto { get; set; }

    [DataMember]

    public DContatto DContatto { get; set; }



    [DataMember]

    public string Cognome { get; set; }

    [DataMember]

    public string Nome { get; set; }

    [DataMember]

    public string RagioneSociale { get; set; }



    private int? tySesso{get; set;}

    [DataMember]

    public DSesso DSesso { get; set; }



    [DataMember]

    public DateTime TsValidita { get; set; }

    [DataMember]

    public DateTime DtNascita { get; set; }



    private int? idComune { get; set; }

    [DataMember]

    public Comune Comune { get; set; }



    [DataMember]

    public string CdFiscale { get; set; }

    [DataMember]

    public string PartitaIva { get; set; }



    private int? tyIso { get; set; }



    [DataMember]

    public DIso DIso { get; set; }



    [DataMember]

    public int? IdUser { get; set; }

    [DataMember]

    public string UserId { get; set; }



    [DataMember]

    public List<Telefono> LsTelefono { get; set; }

    [DataMember]

    public List<Mail> LsMail { get; set; }

    [DataMember]

    public List<Indirizzo> LsIndirizzo { get; set; }



}

and this is my recursively method

    private static object CheckRecursivelyDifference(object old, object nuevo)

    {

        var oType = old.GetType();

        foreach (var oProperty in oType.GetProperties())

        {

            var oOldValue = oProperty.GetValue(old, null); //letto dal SqlServer

            var oNewValue = oProperty.GetValue(nuevo, null);  //letto dal gestionale



            if (oProperty.PropertyType.Module.ScopeName != "CommonLanguageRuntimeLibrary")

                CheckRecursivelyDifference(oOldValue, oNewValue);

            else

            {

                // this will handle the scenario where either value is null

                if (!object.Equals(oOldValue, oNewValue))

                {

                    if (oNewValue == null && oOldValue != null) //vince sempre il vecchio gestionale

                        oProperty.SetValue(nuevo, oOldValue);

                }

            }



        }

        return nuevo;

    }

the method work for a normal class but when read a property as System.Collection.Generic.List<> not work

my question is how i can check System.Collection.Generic.List<> and inheritance property.

thank you in advance for your help

What you can do when it comes to objects that are lists is to check if they are indeed lists,

public static bool IsGenericList(object value)

        {

            if (value == null)

                return false;



            try

            {

                var val =  value as IList;

                if (val == null)

                    return false;



                if ((typeof(BaseConversion)).IsAssignableFrom(val.GetType().GetGenericArguments()[0]))

                {

                    return true;

                }

                else

                {

                    return false;

                }

            }

            catch

            {

                return false;

            }

        }

also exclude indexed parameters like this["test"],etc

objType.GetProperties().Where(x => x.GetIndexParameters().Length == 0 

on your

var oProperty in oType.GetProperties()

line.
