C# OrderBy on nested object Property

I'm using reflection to order by list of objects.
I would like to order this list on a property of a nested object.
This is the code in which I get the list, and I do the sorting of the list
List<DocumentModel> documentList;
if (contractid == -1)
documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListByCustomer(custid, custtypeid);
else
documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListGridByContract(contractid);
if (sord.Equals("asc")) documentList = documentList.OrderBy(x => x.GetType().GetProperty(sidx.ToUpper()).GetValue(x, null)).ToList();
else documentList = documentList.OrderByDescending(x => x.GetType().GetProperty(sidx.ToUpper()).GetValue(x, null)).ToList();
The DocumentModel object has a DocumentModelType property that contains a DocumentStateDesc string property.
Can I sort the list by the DocumentTypeDesc property using reflection? What can I use in the sidx parameter?
Thanks

You should be using x => x.DocumentModelType.GetType().GetProperty(sidx.ToUpper()).GetValue(x.DocumentModelType, null) inside OrderBy clause. Here sidx should be DocumentStateDesc as you mentioned that you want order on this column.
Complete code will be like below.
List<DocumentModel> documentList;
if (contractid == -1)
documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListByCustomer(custid, custtypeid);
else
documentList = helpsi.framework.core.CustomerProvider.DocumentModel.getAllDocumentModelListGridByContract(contractid);
if (sord.Equals("asc"))
documentList = documentList.OrderBy(x => x.DocumentModelType.GetType().GetProperty(sidx.ToUpper()).GetValue(x.DocumentModelType, null)).ToList();
else
documentList = documentList.OrderByDescending(x => x.DocumentModelType.GetType().GetProperty(sidx.ToUpper()).GetValue(x.DocumentModelType, null)).ToList();

One quick and dirty fix is to introduce property in parent class that just returns the property value of another property. Just don't assign XmlElement attribute to it. If the classes are auto-generated you can't change them, but they are probably declared as partial, and then you can add this new property in additional class definition.
public string DocumentModelType_DocumentStateDesc { get => DocumentModelType.DocumentStateDesc; }
But if you want to have a general solution for several properties with several sub-properties then some sort of pathing is required. You could String.Split sidx on some delimiter like '\' or '.', use recursion, and then OrderBy the last item in the path.

Protobuf-net Serializing Parent Class inherited object property marked as [ProtoIgnore()] throwing "No serializer defined for type: System.Object"

All the objects in our system inherit a base class which has got a property of type object.
I have tried adding protoignore attribute to all the properties of the base class as well but that doesn't seem to work as well.
class Program
{
static void Main(string[] args)
{
Vehicle vehicle = new Vehicle();
vehicle.BodyStyleDescription = "4x4";
vehicle.BodyStyleText = "Prestige Medium";
dynamic protobufModel = TypeModel.Create();
AddTypeToModel<Vehicle>(protobufModel);
using (MemoryStream compressed = new MemoryStream())
{
using (GZipStream gzip = new GZipStream(compressed, CompressionMode.Compress, true))
{
protobufModel.Serialize(gzip, vehicle);
}
string str = Convert.ToBase64String(compressed.GetBuffer(), 0, Convert.ToInt32(compressed.Length));
}
}
public static MetaType AddTypeToModel<T>(RuntimeTypeModel typeModel)
{
var properties = typeof(T).GetProperties().Select(p => p.Name).OrderBy(name => name);
return typeModel.Add(typeof(T), true).Add(properties.ToArray());
}
}
Following is the hierarchy of the object
public interface IObjectBaseClass
{
[ProtoIgnore()]
object Parent { get; set; }
[ProtoIgnore()]
bool IsSaved { get; set; }
[ProtoIgnore()]
string XmlAtLoad { get; set; }
}
public class ObjectBaseClass : IObjectBaseClass
{
public ObjectBaseClass()
{
}
[ProtoIgnore()]
internal object _Parent;
[ProtoIgnore()]
internal bool _IsSaved;
[ProtoIgnore()]
internal string _XmlAtLoad;
[ProtoIgnore()]
public bool IsSaved
{
get { return _IsSaved; }
set { _IsSaved = value; }
}
[ProtoIgnore()]
public object Parent
{
get { return _Parent; }
set { _Parent = value; }
}
[ProtoIgnore()]
public string XmlAtLoad
{
get { return _XmlAtLoad; }
set { _XmlAtLoad = value; }
}
}
public class Vehicle : ObjectBaseClass
{
private string _BodyStyleText;
private string _BodyStyleDescription;
public string BodyStyleDescription
{
get { return _BodyStyleDescription; }
set { _BodyStyleDescription = value; }
}
public string BodyStyleText
{
get { return _BodyStyleText; }
set { _BodyStyleText = value; }
}
}

Your problem is that when you do typeModel.Add(typeof(T), true).Add(properties.ToArray()) you are adding all properties of T to the runtime type model, including those marked with ProtoIgnore. You can see this by calling the debugging method protobufModel.GetSchema(typeof(Vehicle)) which returns:
message Object {
}
message Vehicle {
optional string BodyStyleDescription = 1;
optional string BodyStyleText = 2;
optional bool IsSaved = 3;
optional Object Parent = 4;
optional string XmlAtLoad = 5;
}
To avoid adding properties marked with [ProtoIgnore], you could do:
public static MetaType AddTypeToModel<T>(RuntimeTypeModel typeModel)
{
var properties = typeof(T)
.GetProperties()
.Where(p => !p.GetCustomAttributes<ProtoIgnoreAttribute>().Any())
.Select(p => p.Name)
.OrderBy(name => name);
return typeModel.Add(typeof(T), true).Add(properties.ToArray());
}
Alternatively, since you are manually annotating some of your models with protobuf attributes anyway, you could mark the derived types with [ProtoContract(ImplicitFields = ImplicitFields.AllPublic)], e.g.:
[ProtoContract(ImplicitFields = ImplicitFields.AllPublic)]
public class Vehicle : ObjectBaseClass
{
private string _BodyStyleText;
private string _BodyStyleDescription;
public string BodyStyleDescription
{
get { return _BodyStyleDescription; }
set { _BodyStyleDescription = value; }
}
public string BodyStyleText
{
get { return _BodyStyleText; }
set { _BodyStyleText = value; }
}
}
Using either method, the schema for Vehicle becomes:
message Vehicle {
optional string BodyStyleDescription = 1;
optional string BodyStyleText = 2;
}
This is what you require.

How I will generate Xml For the Below code ... code for void getxml() method inside Order class which depends upon Delivery & Recipient Class

Recipient = new Recipient(recipientId, recipientName);
// UserId = SessionHelper.Instance.GetUserId();
// TenantId = SessionHelper.Instance.GetTenantID().ToString();

You should Change prop.GetType() to prop.PropertyType.

I found the solution by myself:
The error was in the MyPropertyDescriptor!
Correction:
class MyPropertyDescriptor : PropertyDescriptor
{
private static readonly Attribute[] nix = new Attribute[0];
private readonly PropertyDescriptor parent;
private readonly PropertyDescriptor child;
public MyPropertyDescriptor(PropertyDescriptor parent, PropertyDescriptor child)
: base(parent.Name + "." + child.Name, nix)

this.parent = parent;
this.child = child;
}
public override object GetValue(object component)
{
var temp = parent.GetValue(component);
if (temp == null) return null;
var temp2 = child.GetValue(temp);
return temp2;
}
public override Type PropertyType
{
get { return child.PropertyType; }
}
public override bool IsReadOnly
{
get { return true; }
}
public override void SetValue(object component, object value)

but the ToXml() response something like this
<Person xmlns:xsi="************" xmlns:xsd="******" ID="******" Name="*****"/><AccessControlEntries/></Person>
but what i want is something like this
<Person Id="****" Name="***" Nombre="****">
<AccessControlEntries/>
<IdentityGroups/>
</Person>

Try using the following Serialize method:
var ns = new XmlSerializerNamespaces();
ns.Add("", "");
serializer.Serialize(writer, this, ns);
