How To Assign the value in OneModel to AnotherModel

How to Assign the value in one model to another model without using AutoMapper ,foreach,and instance and then it will access any way to send value in one model to another model its is possible and then my source model will be byte array ..
This is my source model...
public class OneDriveItem : OneDriveItemBase
{
public string Id { get; set; }
public string Name { get; set; }
public string ETag { get; set; }
public OneDriveIdentitySet CreatedBy { get; set; }
public DateTimeOffset CreatedDateTime { get; set; }
public OneDriveIdentitySet LastModifiedBy { get; set; }
public DateTimeOffset LastModifiedDateTime { get; set; }
public long Size { get; set; }
public string WebUrl { get; set; }
public OneDriveItem[] Children { get; set; }
public OneDriveRemoteItem RemoteItem{ get; set; }
}
This is my Target Model
public class OneDriveModels
{
public string Id { get; set; }
public string Etag { get; set; }
public string Name { get; set; }
public string WebUrl { get; set; }
public string CTag { get; set; }
public long Size { get; set; }
public DateTime CreatedDateTime { get; set; }
public DateTime LastModifiedDateTime { get; set; }
public string DownloadUrlAnnotation { get; set; }
}

You can decide not to look for a shortcut and do it with a constructor/factory method.
For example:
public class OneDriveModels
{
public static FromOneDriveItem( OneDriveItem source)
{
Id = source.Id
ETag = source.ETag
(...)
}

Not getting object data from Json deserialization

I am getting Json data from a web server, but when I try to deserialize it to objects, I am not getting any data. The Json string looks like this:
{"success":true,"data":[{"Id":6,"CustomerGuid":"70b390d8-82d5-4bba-aa68-fc8268a1b1ff","UserName":"victoria_victoria#nopCommerce.com","Email":"victoria_victoria#nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472393)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472393)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":5,"CustomerGuid":"eb9e6f24-f362-4c10-942a-366e2919dc11","UserName":"brenda_lindgren#nopCommerce.com","Email":"brenda_lindgren#nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472363)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472363)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":4,"CustomerGuid":"9f46dbae-6942-410c-90b8-9b38a0890064","UserName":"james_pan#nopCommerce.com","Email":"james_pan#nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472317)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472317)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":3,"CustomerGuid":"6277386b-13ee-427b-9cfe-4ebfa487c340","UserName":"arthur_holmes#nopCommerce.com","Email":"arthur_holmes#nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472253)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472253)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":2,"CustomerGuid":"241f45f1-b38c-4e22-8c5a-743fa3276620","UserName":"steve_gates#nopCommerce.com","Email":"steve_gates#nopCommerce.com","CustomerRoles":[{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":false,"Active":false,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":null,"CreatedOnUtc":"\/Date(1472933472207)\/","LastLoginDateUtc":null,"LastActivityDateUtc":"\/Date(1472933472207)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[]},{"Id":1,"CustomerGuid":"a940dc03-5f52-47d2-9391-8597b3b31cf2","UserName":"tony#lakesideos.com","Email":"tony#lakesideos.com","CustomerRoles":[{"Id":1,"Name":"Administrators","SystemName":"Administrators"},{"Id":2,"Name":"Forum Moderators","SystemName":"ForumModerators"},{"Id":3,"Name":"Registered","SystemName":"Registered"}],"AdminComment":null,"IsTaxExempt":false,"AffiliateId":0,"VendorId":0,"HasShoppingCartItems":true,"Active":true,"Deleted":false,"IsSystemAccount":false,"SystemName":null,"LastIpAddress":"71.185.255.7","CreatedOnUtc":"\/Date(1472933470783)\/","LastLoginDateUtc":"\/Date(1477522483903)\/","LastActivityDateUtc":"\/Date(1477523996553)\/","ExternalAuthenticationRecords":[],"ShoppingCartItems":[{"Id":1,"StoreId":1,"ShoppingCartTypeId":1,"CustomerId":1,"ProductId":18,"AttributesXml":null,"CustomerEnteredPrice":0.0000,"Quantity":1,"CreatedOnUtc":"\/Date(1473801903447)\/","UpdatedOnUtc":"\/Date(1473803336207)\/","IsFreeShipping":false,"IsShipEnabled":true,"AdditionalShippingCharge":0.0000,"IsTaxExempt":false}]}]}
I created these classes from the recommendation given in this link:
recommendation
I used this to create the classes: json2csharp
Response class:
class Response
{
bool success;
IList<Customer> data;
}
Customer class:
class Customer
{
public int Id { get; set; }
public string CustomerGuid { get; set; }
public string UserName { get; set; }
public string Email { get; set; }
public List<CustomerRole> CustomerRoles { get; set; }
public object AdminComment { get; set; }
public bool IsTaxExempt { get; set; }
public int AffiliateId { get; set; }
public int VendorId { get; set; }
public bool HasShoppingCartItems { get; set; }
public bool Active { get; set; }
public bool Deleted { get; set; }
public bool IsSystemAccount { get; set; }
public object SystemName { get; set; }
public string LastIpAddress { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime? LastLoginDateUtc { get; set; }
public DateTime LastActivityDateUtc { get; set; }
public List<object> ExternalAuthenticationRecords { get; set; }
public List<object> ShoppingCartItems { get; set; }
}
CustomerRole class:
class CustomerRole
{
public int Id { get; set; }
public string Name { get; set; }
public string SystemName { get; set; }
}
ExternalAuthenticationRecord class:
class ExternalAuthenticationRecord
{
public int Id { get; set; }
public int CustomerId { get; set; }
public string Email { get; set; }
public object ExternalIdentifier { get; set; }
public object ExternalDisplayIdentifier { get; set; }
public object OAuthToken { get; set; }
public object OAuthAccessToken { get; set; }
public string ProviderSystemName { get; set; }
}
ShoppingCartItem class:
class ShoppingCartItem
{
public int Id { get; set; }
public int StoreId { get; set; }
public int ShoppingCartTypeId { get; set; }
public int CustomerId { get; set; }
public int ProductId { get; set; }
public object AttributesXml { get; set; }
public double CustomerEnteredPrice { get; set; }
public int Quantity { get; set; }
public DateTime CreatedOnUtc { get; set; }
public DateTime UpdatedOnUtc { get; set; }
public bool IsFreeShipping { get; set; }
public bool IsShipEnabled { get; set; }
public double AdditionalShippingCharge { get; set; }
public bool IsTaxExempt { get; set; }
}
I am using this statement to deserialzie the Json string: Response res = (Response)JsonConvert.DeserializeObject(customerJson, (typeof(Response)));
When I stop it in the debugger, it shows "res" as data: null and success: false.
I am not getting any errors. It is just not giving me the data from the Json string.
Any help that anybody can provide to figure out why I'm not getting the data I want in "res", would be gratefully appreciated.
Thanks,
Tony

The problem is related to the accessibility level in your Response class. By default the fields, property and method are private so JsonConvert is not able to fill the properties.
Change the class as follow:
class Response
{
public bool success {get; set;}
public IList<Customer> data {get; set;}
}
And it wil works.
Another improvement is related to the JsonConvert use. To avoid the explicit cast use this type conversion: JsonConvert.DeserializeObject<T>(string) where T will be Response

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.
