C# Linq set merged lists as datasource

I'm currently merging to lists will be the datasource of a gridview. This is my code:
// Get models
var products = await API.Zelkon.Products.GetAll();
var productsCurrencies = await API.Zelkon.CurrenciesBackend.Get();
// Merge lists
var results = products.Item1.Zip(productsCurrencies.Item1, (x, y) => new Tuple<Models.Products, Models.Zelkon.CurrenciesBackend>(x, y));
// Create datasource
var datasource = results.Select(r => new { r.Item2.price, r.Item2.setup_fee, r.Item1.product_number });
GridProducts.DataSource = datasource;
// GridProducts.VisibleColumns("name");
UI.CustomizeGridDefault(GridProducts);
My problem is that the value of r.Item2.setup_fee is always the value of the first row. I have checked the collection and the data is correct there.
Am I doing something wrong?
Below are the structures:
class CurrenciesBackend
{
public string currency_name { get; set; }
public string currency_code { get; set; }
public double price { get; set; }
public double recommended_price { get; set; }
public double setup_fee { get; set; }
public int product_number { get; set; }
}
class Products
{
public string name { get; set; }
public string description { get; set; }
public string invoice_layout { get; set; }
public string layout_number { get; set; }
public string payment_terms_name { get; set; }
public string payment_terms_number { get; set; }
public DateTime creation_date { get; set; }
public int enabled { get; set; }
public int is_subscription { get; set; }
public int is_delivery_required { get; set; }
public int allow_discount { get; set; }
public int allow_trial { get; set; }
public int max_discount { get; set; }
public int max_discount_duration { get; set; }
public int vat_percentage { get; set; }
public int trial_period { get; set; }
public int binding_period { get; set; }
public int days_of_credit { get; set; }
public int unit { get; set; }
public string allowed_country_codes { get; set; }
public int product_number { get; set; }
public int authorize_invoice { get; set; }
}
Thanks in advance

MongoDB wont let me save Object possible circular reference

I am trying to save to the database the updated Account details object which contains a list of Player objects in it.
public class AccountDetails {
public String Id { get; set; }
public String Username { get; set; }
public String Email { get; set; }
public String Password { get; set; }
public String Token { get; set; }
public int PremiumDays { get; set; }
public List<Player> Players { get; set; }
public String LastLogin { get; set; }
public int AdminLevel { get; set; }
public int Banned { get; set; }
public int Muted { get; set; }
It seems to get this error on the Players part,
MongoDB.Bson.BsonSerializationException: 'Maximum serialization depth exceeded (does the object being serialized have a circular reference?).'
I have looked through the references for Player and the inherited GameObj but I cannot seem to find what might be causing this circular reference,
This is my Player Object,
public PlayerClass Class { get; set; }
public int Level { get; set; }
public string Name { get; set; }
public string Title { get; set; }
public List<Skill> Skills { get; set; }
public List<ArchewoodGameServer.core.Shared.Utils.Attribute> Attributes { get; set; }
public int AttributePoints { get; set; }
public int CurrentHealth { get; set; }
public int MaxHealth { get; set; }
public int CurrentMana { get; set; }
public int MaxMana { get; set; }
public int CurrentExp { get; set; }
public int MaxExp { get; set; }
[JsonIgnore]
public List<Node> Path = new List<Node>();
[JsonIgnore]
public int PathCount = 0;
[JsonIgnore]
public int HealthTick = 0, AttackTick = 10000, AnimTick = 0, MaxAnimTick = 20;
public float AttackSpeed { get; set; }
public ushort AttackRange { get; set; }
and this is my GameObj class,
public string Id { get; set; }
public float X { get; set; }
public float Y { get; set; }
public int O { get; set; }
public int A { get; set; }
public int T { get; set; }
public float S { get; set; }
[JsonIgnore]
public Instance Instance { get; set; }
[JsonIgnore]
public string InstanceID { get; set; }
[JsonIgnore]
public List<String> playerInteractions = new List<string>();
[JsonIgnore]
public int LastProcessedSequence { get; set; }
public string TargetEntity { get; set; }
public ushort PrivateId { get; set; }

The [JsonIgnore] were not working with mongos parser so I changed the structure to not rely on these tags and it was resolved.

I resolved problem in our core project on this way.
'
using Newtonsoft.Json;
using AutoMapper;
var stringContent = JsonConvert.SerializeObject(_mapper.Map<DataDTO>(newdata), new JsonSerializerSettings { ReferenceLoopHandling = ReferenceLoopHandling.Ignore }).ToString();
_mongoService.Save(JsonConvert.DeserializeObject<DataDTO>(stringContent));
//mongo service save method
public async void Save(DataDTO dataDTO)
{
await collection.InsertOneAsync(dataDTO));
}

Extracting JSON data Xamarin

I am working a Xamarin.Forms App that uses the Azure Face API. With this API you retrieve a JSON response (See Below).
I want to extract the gender of the person in the image but am having trouble with it as I am very new to this.
I extract the full JSON response into a string but I would like to be able to extract data such as the 'Gender' or the 'Age' of the person in the image.
[{"faceId":"9448dfe4-afb6-4557-94fe-010fc439ff36","faceRectangle":{"top":635,"left":639,"width":789,"height":789},"faceAttributes":{"smile":0.187,"headPose":{"pitch":0.0,"roll":-1.6,"yaw":-7.9},"gender":"male","age":34.6,"facialHair":{"moustache":0.5,"beard":0.6,"sideburns":0.6},"glasses":"NoGlasses","emotion":{"anger":0.0,"contempt":0.69,"disgust":0.0,"fear":0.0,"happiness":0.187,"neutral":0.12,"sadness":0.002,"surprise":0.0},"blur":{"blurLevel":"low","value":0.15},"exposure":{"exposureLevel":"overExposure","value":0.85},"noise":{"noiseLevel":"medium","value":0.42},"makeup":{"eyeMakeup":false,"lipMakeup":false},"accessories":[],"occlusion":{"foreheadOccluded":false,"eyeOccluded":false,"mouthOccluded":false},"hair":{"bald":0.02,"invisible":false,"hairColor":[{"color":"brown","confidence":1.0},{"color":"black","confidence":0.95},{"color":"other","confidence":0.22},{"color":"blond","confidence":0.11},{"color":"gray","confidence":0.05},{"color":"red","confidence":0.04}]}}}]
This is how I set the JSON data to a string.
string contentString = await response.Content.ReadAsStringAsync();

You usually want to create a class that represents your response e. g. Person. Then you could use the Newtonsoft.Json nuget package to deserialize the object.:
var person = JsonConvert.DeserializeObject<Person>(contentString);
Now you can access the values like:
person.Gender

Using Newtonsoft.Json:
var results = JsonConvert.DeserializeObject<AzureFace>(contentString);
Debug.WriteLine(results.faceAttributes.age);

String or binary data would be truncated.The statement has been terminated while removing data

I have a PriceId and I get some PriceGaranties by it and I am trying to delete PriceGaranties by updating Price and see this error.
Here is the code:
public void DeletePriceGaranties(int priceId)
{
var deletedPriceGaranties = context.PriceGaranties.Where(p => p.PriceId == priceId).ToList();
foreach (var priceGaranty in deletedPriceGaranties)
{
context.PriceGaranties.Remove(priceGaranty);
context.SaveChanges();
}
}
The error is:
String or binary data would be truncated. The statement has been
terminated.
Update
Here are the models:
public class Price
{
public int PriceId { get; set; }
public int ProductId { get; set; }
public int ClassId { get; set; }
public int ClassPartnerId { get; set; }
public int UserId { get; set; }
public decimal Cost { get; set; }
public string Url { get; set; }
public string Description { get; set; }
public DateTime LastUpdate { get; set; }
public bool Enable { get; set; }
public int CostTypeId { get; set; }
public int Value { get; set; }
public Class Class { get; set; }
public Product Product { get; set; }
public User User { get; set; }
public List<OldPrice> OldPrices { get; set; }
public List<PriceColor> PriceColors { get; set; }
public List<PriceGaranty> PriceGaranties { get; set; }
public ClassPartner ClassPartner { get; set; }
}
public class PriceGaranty
{
public int PriceGarantyId { get; set; }
public int PriceId { get; set; }
public int GarantyId { get; set; }
public Comparing.Model.Price.Price Price { get; set; }
}
And all of string types are nvarchar(MAX).

You have specified the length of the string in your database to be shorter than what you are trying to add to it. E.g. you may have set a varchar length in your database to be of length 10 but the string you want to add is 11, 15, 20 etc characters. The database doesnt know what to do with it so it just cuts off the excess characters. Try setting the field length in your database to a larger length.

Cannot Serialize JSON

I am trying to access data from a json at this url : http://na.lolesports.com/api/gameStatsFantasy.json?tournamentId=104.
I used a website called http://json2csharp.com/ to help create classes to serialize. It worked but I noticed the JSON had many duplicate instances of the same gameID, playerID and teamID(e.g one named Game2998 and Game29982 or team4 and team42).
