Probably, in the 2nd line you should write hb.DocId equals hbi.HallBanquetId or hb.DocId equals hbi.DocId instead of hb.DocId equals hbi.HallBanquet (It depends on how your foreign key pointing from item to banquet is named).

I serialize it with the following code:
string data = Newtonsoft.Json.JsonConvert.SerializeObject(UniversalModel.Parastatiko,Formatting.None , new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
When I try to deserialize back to the object I get the exception error: ArgumentException.
The code to deserialize is this.
Findoc FFF = Newtonsoft.Json.JsonConvert.DeserializeObject<Findoc>(data, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore });
Any tips on what I am doing wrong?

It may just be a typo in the question but separating the Serializer arguments on to their own lines shows you are passing a UniversalModel.Parastatiko in as the first argument...which I don't think is correct.
string data = Newtonsoft.Json.JsonConvert.SerializeObject(
UniversalModel.Parastatiko,
Formatting.None,
new JsonSerializerSettings {
NullValueHandling = NullValueHandling.Ignore
}
);

Json data deserialzation returning null value for a property

.Net BinaryFormater System.ArgumentNullException: Object Graph cannot be null. Parameter name: graph

I'm attempting to serialize a System.Collections.Generic.List of objects but am running into an error I can't figure out.
The objects I am trying to serialize are pretty vanilla, just a lot of strings and integers properties.
I'm using the following code to serialize a list of objects.
private static Boolean WriteItemDataList(List<ItemData> itemDataList)
{
try
{
using (Stream stream = File.Open(#"H:\1.cache", FileMode.Create))
{
BinaryFormatter binaryFormatter = new BinaryFormatter();
binaryFormatter.Serialize(stream, itemDataList);
}
}
catch (Exception exception)
{
Trace.WriteLine(exception.ToString());
return false;
}
return true;
}
I am getting this error.
A first chance exception of type 'System.ArgumentNullException' occurred in mscorlib.dll

The documentation for BinaryFormatter.Serialize states that it will throw an ArgumentNullException if either of the serializationStream or graph parameters are null. Since the message specifically says "Object graph cannot be null" that means that the graph parameter is null, so the itemDataList parameter to your WriteItemDataList method must be null.

InnerException:When converting a string to DateTime. parse the string to date the date before putting each variable into the DateTime object

I am trying to deserialize XML returned from an API call but am getting "InnerException:When converting a string to DateTime. parse the string to date the date before putting each variable into the DateTime object"
The XML looks like this
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<agentInventory xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:N1="demo.org.uk/demo/CustomsStatus" xmlns:N2="demo.org.uk/demo/UnLocation" xmlns:N3="demo.org.uk/demo/AirCarrier" xmlns="demo.org.uk/demo/AgentInventory">

</agentInventory>
The code used to deserialize the XML is
if (storeXmlInventoryReturnData != null)
{
//DeSerialize XML from storeXmlInventoryReturnData variable
agentInventory myInventoryResponse = null;
XmlSerializer xmlSerializer = new XmlSerializer(typeof(agentInventory));
myInventoryResponse = (
agentInventory)xmlSerializer.Deserialize(new StringReader(storeXmlInventoryReturnData)
);
Console.WriteLine(
#"\n\n\n INVENTORY RETURN DATA FOR AWB: {0}-{1} \n\n

,
myInventoryResponse.masterAirwayBillPrefix,

myInventoryResponse.destinationPort,
myInventoryResponse.arrivalPort,

myInventoryResponse.sdc,
myInventoryResponse.grossWeight,
myInventoryResponse.goodsDescription
);
Console.ReadLine();
}
else
{
Console.Write("No data returned");
}
}
The exception is thrown at;
myInventoryResponse = (
agentInventory)xmlSerializer.Deserialize(new StringReader(storeXmlInventoryReturnData));
I guess I need to convert the myInventoryResponse.flightDate to a DateTime object but I am at a loss how to achieve this?

For my own sanity sake, I tried getting the provided XML to work with your classes and the nullable DateTime fields.
For them to work, replace the below properties with those linked below.
The default value for a DateTime object is DateTime.MinDate, so if the incoming value is null or empty, then the property will have a value of DateTime.MinDate anyway, for this you might need to additional validation/changes if your code needs to cater for this.

'does not implement interface member 'System.ICloneable.Clone()'

I'm having a small issue calling in the Icloneable interface
I've told the class I want to use the interface as such:
class UnitClass: ICloneable
and have placed in a function for Cloning
public Object Clone()
{
return this.MemberwiseClone();
}
however for some reason the program is telling me that I have not implemented System.ICloneable.clone() I even tried giving the function the explicit name like so...
public Object System.ICloneable.Clone()
but with little effect, anybody know what I'm doing wrong?
