Xamarin rest web service doesn't deserialize

I want to use rest with get method. My code is below;
public class RegisterPage : ContentPage
{
Label label, l4, label2;
public RegisterPage()
{
Button btn = new Button
{
Text = "register"
};
btn.Clicked += Btn_Clicked;
label = new Label();
l4 = new Label();
label2 = new Label();
Content = new StackLayout
{
Children = {
btn,
label,
l4,
label2
}
};
}
private async void Btn_Clicked(object sender, EventArgs e)
{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Add(Constants.API_KEY_HEADER_KEY, Constants.API_KEY);
string URL = Constants.URL;
var response = await client.GetAsync(URL);
var content = await response.Content.ReadAsStringAsync();
var result = JsonConvert.DeserializeObject<Models.Result>(content);
label.Text = result.Success.ToString();
l4.Text = result.Error.ToString();
label2.Text = ((RegisteredDevice)result.Retval).Clientuuid + " - " + ((RegisteredDevice)result.Retval).Deviceuuid;
}
}
The url is working good. And my content value has json string. But the serialization is not working.
var result = JsonConvert.DeserializeObject(content);
This code doesn't deserilize.
My model is;
public class Result
{
private object retval = null;
private bool success = false;
private Error error = null;
internal Error Error
{
get { return error; }
set { error = value; }
}
public bool Success
{
get { return success; }
set { success = value; }
}
public object Retval
{
get { return retval; }
set { retval = value; }
}
}
Json:
{
"result":{
"retail":{
"#xsi.type":"registeredDevice",
"clientuuid":"28asgargb-acfe‌​-41dfgsdg51",
"deviceuuid":123456
},
"success":true
}
}

I think the problem comes from :
private object retval = null;
So for me the best way to construct serialization objects in C# is to use this web site :
http://json2csharp.com/
This will tell you if your json is correct and he will generate the classes you need for you, here the classes generated by json2csharp
public class Retail
{
public string __invalid_name__#xsi.type { get; set; }
public string clientuuid { get; set; }
public int deviceuuid { get; set; }
}
public class Result
{
public Retail retail { get; set; }
public bool success { get; set; }
}
public class RootObject
{
public Result result { get; set; }
}

Call only Get Accessors of property

please tell me how can i call only the get method of this property in another method .
for example
public List<EmployeeData> LOP
{
get
{
if (_lop == null)
{
_lop = new List<DTPackage>();
}
return _lop;
}
set
{
_lop = value;
}
}
i want to call only get method of this property.

public List<EmployeeData> LOP
{
get
{
if (_lop == null)
{
_lop = new List<DTPackage>();
}
return _lop;
}
set
{
_lop = value;
}
}
var lop = LOP; // here POP get will be called
LOP = myEmployeeList //here POP set will be called
You can make set to private to avoid access from other classes or remove set for readonly

These are all compilable variants of .Net properties:
// Shorthand
public string MyProperty1 { get; set; }
public string MyProperty2 { get; private set; }
public string MyProperty3 { get; }
// With backing field
private string _myProperty4;
private string _myProperty5;
private readonly string _myProperty6;
public string MyProperty4
{
get { return _myProperty4; }
set { _myProperty4 = value; }
}
public string MyProperty5
{
get { return _myProperty5; }
private set { _myProperty5 = value; }
}
public string MyProperty6
{
get { return _myProperty6; }
}
MSDN
Usage:
string myString = MyProperty4; // Calls get on MyProperty4
MyProperty4 = "Hello World" // Calls set on MyProperty4
MyProperty6 = "Hello World" // Will not be compilable

Custom Collection/List To Store Custom Objects

I have a customer object class:
public class customerObject
{
private string _address1;
private string _address2;
private string _address3;
private string _category;
private string _country;
private string _county;
private string _custcode;
private string _fullname;
private string _int_rep_hou;
private string _int_rep_key;
private double _lat;
private double _lng;
private string _postcode;
private string _rep_code;
private string _telephone;
public customerObject()
{
}
public string Address1
{
get { return _address1; }
set { _address1 = value; }
}
public string Address2
{
get
{
return _address2;
}
set { _address2 = value; }
}
public string Address3 { get { return _address3; } set { _address3 = value; } }
public string Category
{
get { return _category; }
set { _category = value; }
}
public string Country { get { return _country; } set { _country = value; } }
public string County { get { return _county; } set { _county = value; } }
public string Custcode
{
get { return _custcode; }
set { _custcode = value; }
}
public string Fullname
{
get { return _fullname; }
set { _fullname = value; }
}
public string Int_rep_hou
{
get { return _int_rep_hou; }
set { _int_rep_hou = value; }
}
public string Int_rep_key
{
get { return _int_rep_key; }
set { _int_rep_key = value; }
}
public double Lat { get { return _lat; } set { _lat = value; } }
public double Lng { get { return _lng; } set { _lng = value; } }
public string Postcode { get { return _postcode; } set { _postcode = value; } }
public string Rep_code
{
get { return _rep_code; }
set { Rep_code = value; }
}
public string Telephone { get { return _telephone; } set { _telephone = value; }
}
}
I have a CustomCollections class
public class CustomerCollection
{
public List<customerObject> Customers { get; set; }
}
My method that loops through dt rows and converts to a customer object
public List<Valueobjects.CustomerCollection> dolist(DataTable temptablename)
{
//Create Collection Object
Valueobjects.CustomerCollection Collection = new Valueobjects.CustomerCollection();
foreach (DataRow row in temptablename.Rows)
{
//Create Customer Object
Valueobjects.customerObject Customer = new Valueobjects.customerObject();
//set values of customer object
Customer.Rep_code = "";
Customer.Int_rep_key = "";
Customer.Int_rep_hou = "";
Customer.Fullname = row["Fullname"].ToString().Trim();
Customer.Custcode = row["Custcode"].ToString().Trim();
Customer.Category = row["Category"].ToString().Trim();
Customer.Address1 = row["Address1"].ToString().Trim();
Customer.Address2 = row["Address2"].ToString().Trim();
Customer.Address3 = row["Address3"].ToString().Trim();
Customer.Postcode = row["Postcode"].ToString().Trim();
Customer.Country = row["Country"].ToString().Trim();
Customer.Telephone = row["Telephone"].ToString().Trim();
Customer.Lat = Convert.ToDouble(row["Lat"]);
Customer.Lng = Convert.ToDouble(row["Lng"]);
Customer.County = row["County"].ToString().Trim();
//add to the collection (list)
Collection.Customers.Add(Customer);
}
temptablename = null;
return Collection;
}
However when I create a new Customer object and a new CustomerCollection object I am getting an error when adding the customer to the collection list.
Error:
Error 32 Cannot implicitly convert type
'Classes.Valueobjects.CustomerCollection' to
'System.Collections.Generic.List'

Your method is returning a List<CustomerCollection>:
public List<Valueobjects.CustomerCollection> dolist(DataTable temptablename)
{
//...
}
But the code is trying to return a CustomerCollection:
return Collection;
Just as the error says, these two types are different.
If a CustomerCollection is already a collection of customers, then semantically what is a List<Valueobjects.CustomerCollection>? A collection of collections? It seems like you're over-pluralizing your objects :)
There are two approaches here. Either return a CustomerCollection from the method:
public CustomerCollection dolist(DataTable temptablename)
{
//...
}
Or use a List<Customer> if you want to use generic lists as your collection containers:
public List<Customer> dolist(DataTable temptablename)
{
//...
var Collection = new List<Customer>();
//...
Collection.Add(Customer);
//...
return Collection;
}
Side note: You may want to stick to C# conventions for variable naming. As you can see from the code highlighting here on Stack Overflow, your variable names can easily be mistaken for classes/types, which can cause confusion when supporting the code.

Return a CustomerCollection instead of a List<Valueobjects.CustomerCollection>:
public Valueobjects.CustomerCollection Dolist(DataTable temptablename)
{
// ...
Your object has a list, it is not a list.

C# - Marshall by value problem!

Here is the thing, I have a problem creating a new object using the remote mechanism "marshal by value".
Here is my class:
[Serializable]
internal class Empleado_MBV
{
public Empleado_MBV()
{
Id = 123456789;
Nombres = "NotEntry";
Apellidos = "NotEntry";
FechaNacimiento = DateTime.MinValue;
Direccion = "NotEntry";
Metapreferencias = "NotEntry";
}
private List<Multas> _multas;
internal List<Multas> Multas
{
get { return _multas; }
set { _multas = value; }
}
private int _id;
public int Id
{
get { return _id; }
set { _id = value; }
}
private string _nombres;
public string Nombres
{
get { return _nombres; }
set { _nombres = value; }
}
private string _apellidos;
public string Apellidos
{
get { return _apellidos; }
set { _apellidos = value; }
}
private DateTime _FecNac;
public DateTime FechaNacimiento
{
get { return _FecNac; }
set { _FecNac = value; }
}
private string _direccion;
public string Direccion
{
get { return _direccion; }
set { _direccion = value; }
}
private string _metapreferencias;
public string Metapreferencias
{
get { return _metapreferencias; }
set { _metapreferencias = value; }
}
public string _AppDomainHost
{
get { return AppDomain.CurrentDomain.FriendlyName.ToString(); }
}
}
But when I try to create an object in another "appdomain", the property "_AppDomainHost" of "Empleado" does not show the "appdomain" I had created, but show the "appdomain" by default. Some ideas?
AppDomain ad1 = AppDomain.CreateDomain("NewAppDomain");
//Crear new object in my new AD.
Empleado_MBV mbv_emp = (Empleado_MBV)ad1.CreateInstanceFromAndUnwrap("DEMO_MBV_MBR.exe", "DEMO_MBV_MBR.Empleado_MBV");
Console.WriteLine(AppDomain.CurrentDomain.FriendlyName.ToString());
Console.WriteLine("MBV : {0}",mbv_emp._AppDomainHost.ToString());
Console.ReadLine();
Result:
DEMO_MBV_MBR.vshost.exe
MBV : DEMO_MBV_MBR.vshost.exe
The result that I want:
DEMO_MBV_MBR.vshost.exe
MBV : NewAppDomain

You need to store AppDomain in Empleado_MBV's constructor.
What you are doing right now is displaying current AppDomain using its Current static property. It will return the AppDomain where current code is being executed.
Example:
private string _appDomainHost;
public string _AppDomainHost
{
get { return _appDomainHost; }
}
and in constructor:
_appDomainHost = AppDomain.CurrentDomain.FriendlyName.ToString();
