I have a list of Invoice and I have to deserializate it. First I serialized to xml and it ways easy to find and apply. This time I can not deserializate the Item lists in the xml. For example, this is my xml serialized row:
<?xml version="1.0" encoding="utf-8"?>
<Body xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<Invoice>4711</Invoice>
<Table>8</Table>
<Outlet>3</Outlet>
<User>17</User>
<Creation>20140101</Creation>
<Item>
<Type>Revenue</Type>
<Productgroup>5</Productgroup>
<TotalAmount>6</TotalAmount>
<TaxClassification>1</TaxClassification>
<Text>Pizza Tonna</Text>
</Item>
<Item>
<Type>Gratuity</Type>
<TotalAmount>1.5</TotalAmount>
<Text>Tip</Text>
</Item>
<Item>
<Type>Payment</Type>
<TotalAmount>7.5</TotalAmount>
<ResNo>4812</ResNo>
</Item>
</Body>
As you see, I have a Body root xml and 5 mainly row but in the deep I have more than one Item data which is a list. If I had one item for each Invoice, it would be easy to do but during tough researches, I could not get any point.
Let me sahre with you what I did. These are my Body and Item Classes:
[XmlRoot("Body")]
public class Body
{
[XmlElement("Invoice")]
public int Invoice { get; set; }
[XmlElement("Table")]
public int Table { get; set; }
[XmlElement("Outlet")]
public int Outlet { get; set; }
[XmlElement("User")]
public int User { get; set; }
[XmlElement("Creation")]
public int Creation { get; set; }
[XmlElement("Item")]
public List<Item> Items { get; set; }
}
[XmlRoot("Item")]
public class Item
{
[XmlElement("Type")]
public string? Type { get; set; }
[XmlElement("Productgroup")]
public int? Productgroup { get; set; }
public bool ShouldSerializeProductgroup()
{
return Productgroup.HasValue;
}
[XmlElement("TotalAmount")]
public double? TotalAmount { get; set; }
public bool ShouldSerializeTotalAmount()
{
return TotalAmount.HasValue;
}
[XmlElement("TaxClassification")]
public double? TaxClassification { get; set; }
public bool ShouldSerializeTaxClassification()
{
return TaxClassification.HasValue;
}
[XmlElement("Text")]
public string? Text { get; set; }
[XmlElement("ResNo")]
public int? ResNo { get; set; }
public bool ShouldSerializeResNo()
{
return ResNo.HasValue;
}
}
And here is my main program for serialization and nice versa.
static void Main(string[] args)
{
try
{
Body body = new Body
{
Invoice = 4711,
Table = 8 / 1,
Outlet = 3,
User = 17,
Creation = 20140101,
Items = new List<Item>()
{
new Item{Type="Revenue",Productgroup = 5,TotalAmount=6.00,TaxClassification=1,Text="Pizza Tonna"},
new Item{Type="Gratuity",TotalAmount=1.50,Text="Tip"},
new Item{Type="Payment",TotalAmount=7.50,ResNo=4812}
}
};
XmlSerializer xmlSerializer = new XmlSerializer(typeof(Body));
StreamWriter sw = new StreamWriter("CloseInvoice.xml");
xmlSerializer.Serialize(sw, body);
sw.Close();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
try
{
XmlSerializer xmlSerializer = new XmlSerializer(typeof(Body));
StreamReader sr = new StreamReader("CloseInvoice.xml");
Body body = (Body)xmlSerializer.Deserialize(sr);
Console.WriteLine("Invoice Information");
Console.WriteLine("Type: "+body.Invoice);
Console.WriteLine("Table: " + body.Table);
Console.WriteLine("Outlet: " + body.Outlet);
Console.WriteLine("User: " + body.User);
Console.WriteLine("Creation: " + body.Creation);
}
catch (Exception)
{
throw;
}
}
I tried all loops but I cannot write the Items on the console. Can you please help me? Thank from now.
Edit: Here is my console out. I can get Body Rows but I want to get Item List in the xml too.
