I have 2 classes which have some identical properties. I stock into a list properties from 1st class, and after that, I want to take some needed properties and put them into a list of 2nd class type. I've made cast sequence through C# and that runs OK, but I must do with LINQ. I tried to do something but without good results. Help me please with suggestions.
1st Class:
public class ServiceInfo {
private long _id;
public long ID {
get { return this._id; }
set { _id = value; }
}
private string _name;
public string Name {
get { return this._name; }
set { _name = value; }
}
private long _qty;
public long Quantity {
get { return this._qty; }
set { _qty = value; }
}
private double _amount;
public double Amount {
get { return this._amount; }
set { _amount = value; }
}
private string _currency;
public string Currency {
get { return this._currency; }
set { _currency = value; }
}
private DateTime? _date;
public DateTime? Date {
get { return this._date; }
set { _date = value; }
}
}
2nd Class:
class InvoiceWithEntryInfo {
private string currencyField;
private long IdField;
public long IdIWEI {
get { return this.IdField; }
set { IdIWEI = value; }
}
private string nameField;
public string NameIWEI {
get { return this.nameField; }
set { NameIWEI = value; }
}
private long qtyField;
public long QuantityIWEI {
get { return this.qtyField; }
set { QuantityIWEI = value; }
}
private double amountField;
public double AmountIWEI {
get { return this.amountField; }
set { AmountIWEI = value; }
}
private DateTime dateField;
public DateTime? DateIWEI {
get { return this.dateField; }
set { DateIWEI = value; }
}
public string OwnerIWEI {
get; set;
}
}
C# sample which runs OK: ...
var sil = new List<ServiceInfo>();
var iweil = new List<InvoiceWithEntryInfo>();
...
if (sil != null)
{
foreach (ServiceInfo item in sil)
{
iweil.Add(new InvoiceWithEntryInfo
{
IdIWEI = item.ID,
AmountIWEI = item.Amount,
DateIWEI = item.Date
});
}
LINQ sample which doesn't run OK:
iweilCOPY = sil.ConvertAll<InvoiceWithEntryInfo>(a => (InvoiceWithEntryInfo)a);
iweilCOPY = sil.FindAll(a => (sil is InvoiceWithEntryInfo)).ConvertAll<InvoiceWithEntryInfo>(a => (InvoiceWithEntryInfo)a);
var iweilCopy = sil.Select(item => new InvoiceWithEntryInfo()
{
IdWEI = item.Id,
NameWEI = item.Name,
....
}).ToList();
