Update property for Realm entry

I using Realm database at my Xamarin project
I have realm object with this model
public class UserModel: RealmObject
{
public string Id { get; set;}
public string Email { get; set; }
public string Password { get; set; }
public byte[] UserAvatar { get; set; }
public string ApiKey { get; set; }
public string Name { get; set; }
public string Surname { get; set; }
public string Birthday { get; set; }
public int Country_id { get; set; }
public bool IsAuthorized { get; set; }
public string Base64Avatar { get; set; }
public string Telephone { get; set; }
}
I need to update Name property.
How I try to do this
var realm = Realm.GetInstance();
var user_check = realm.All<UserModel>().First();
user_check.Name = "Test"
and get this error
How I can fix this?

Adding/Updating/Deleting to Realm object must be done inside a transaction, easiest way is to wrap it in Write method.
realm.Write(() =>
{
user_check.Name = "Test";
});
For more info, check the Rleam Write docs

Have you tried changing:
{"entity":"event","account_id":"acc_8yTsyb2WJOlcka","event":
to
{"entity":"event","account_id":"acc_8yTsyb2WJOlcka","events":
That would better match your class definition. Or rename your class field to event.

There is a useful visual studio function for converting a json object to c# classes.
Copy the JSON into the clipboard. (helps if the JSON object properties holds data, to determine the data type)
Go to visual studio and place cursor where you'd like to paste in the c# classes.
click edit => paste special => paste json as classes

public List<string> channels { get; set; }
public string doc_type { get; set; }
public bool downloaded { get; set; }

}

Based on my previous experience with JSON.NET, it can be a bit tricky the translation from JSON to the right class. The web site above have provided me all the time the right class. The only exception is the Wikipedia API because it's a dynamic API and you need to do a small trick.
Also, keep in mind all properties must be public because if something is private (like in your question), it is not going to be accessible by the translator or anything else. I hope it's helpful.

Either mark all the properties in your class as public, or explicity add JsonProperty attribute to each property as follows:
public class UserDetails
{
[JsonProperty("_id")]
String _id { get; set; }
...
}

When using Json Validator I got "The root JSON data must represent an object or an array", therefore indicating that your JSON is most likey not correct.
This is why the string cannot be serialized to your class, leaving the properties null.
You should show us your serialization process to find out about where the error is.

REST Api returning different object names for the same object, how to handle with RestSharp?

I'm programming a C# implementation for the Qualtrics API (v 2.5) using RestSharp. When calling the method getUserIds, it returns a list of users in JSON format (see the example output below).
The problem/question I face is that for each user object (the list of objects under Result) it generates a different id, starting with URH_. When using json2csharp it assumes ofcourse that it's always a different class, while in fact it's absolutely the same one as you can see in the output, and as is stated in the documentation of the api. How can I best resolve this - so that I can make a class UserData that I can reuse? Because now I obviously always see these random URH_ prefixed classes in each response.
NOTE: I was thinking I could try to massage the response first, and when I get the response replace each URH_ prefixed object under the root Result object with a "UserData" string - but I feel this is breaking the rules a bit, and thought the community would have a better solution?
Below is the raw JSON output (note that I removed sensitive information):
{"Meta":{"Status":"Success","Debug":""},"Result":{"URH_3wpA9pxGbE0c7Xu":{"DivisionID":null,"UserName":"user.name#domain.com","UserFirstName":"x","UserLastName":"x","UserAccountType":"UT_4SjjZmbPphZGKDq","UserEmail":"x.x#x.x","UserAccountStatus":"Active"},"URH_57vQr8MVXgpcPUo":{"DivisionID":"DV_XXXXXXXX","UserName":"jxxxx#xx.xxx","UserFirstName":"X","UserLastName":"X","UserAccountType":"UT_BRANDADMIN","UserEmail":"xxxx#xxg.xxx","UserAccountStatus":"Active"},"URH_6ujW1EP0QJOUaoI":{"DivisionID":"DV_XXXXXXXYZ","UserName":"x.xckx#xxx.xyz","UserFirstName":"x","UserLastName":"x","UserAccountType":"UT_XXXXXABCD","UserEmail":"c.c#cc.com","UserAccountStatus":"Active"}}}
This is what I get when generating a model using json2csharp:
public class Meta
{
public string Status { get; set; }
public string Debug { get; set; }
}
public class URH3wpA9pxGbE0c7Xu
{
public object DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}
public class URH57vQr8MVXgpcPUo
{
public string DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}
public class URH6ujW1EP0QJOUaoI
{
public string DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}
public class Result
{
public URH3wpA9pxGbE0c7Xu URH_3wpA9pxGbE0c7Xu { get; set; }
public URH57vQr8MVXgpcPUo URH_57vQr8MVXgpcPUo { get; set; }
public URH6ujW1EP0QJOUaoI URH_6ujW1EP0QJOUaoI { get; set; }
}
public class RootObject
{
public Meta Meta { get; set; }
public Result Result { get; set; }
}

It's simple - just use Dictionary<string, UserData> generic type for Result field:
public class Response
{
public Meta Meta { get; set; }
public Dictionary<string, UserData> Result { get; set; }
}
public class Meta
{
public string Status { get; set; }
public string Debug { get; set; }
}
public class UserData
{
public string DivisionID { get; set; }
public string UserName { get; set; }
public string UserFirstName { get; set; }
public string UserLastName { get; set; }
public string UserAccountType { get; set; }
public string UserEmail { get; set; }
public string UserAccountStatus { get; set; }
}

EF4.1 Code First Question

I want to create my first application using the EF 4.1 Code First Model. I want to model a magazine subscription but just want to check that my POCO classes are fit for purpose.
The following are my classes. Am I missing anything?
Should Customer be a member of Subscription or should it be just that List be a member of Customer?
Thanks.
public class Subscription
{
public int SubscriptionID { get; set; }
public string CardNumber { get; set; }
public DateTime StartDate { get; set; }
public DateTime EndDate { get; set; }
public decimal NetPrice { get; set; }
public decimal Tax { get; set; }
public decimal Discount { get; set; }
public string PromotionalCode { get; set; }
public Customer Customer{ get; set; }
}
public class Customer {
public int CustomerID { get; set; }
public string Title { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public PostalAddress PostalAddress { get; set; }
public string EmailAddress { get; set; }
public string Telephone { get; set; }
public string Mobile { get; set; }
public DateTime DateOfBirth { get; set; }
public string Username { get; set; }
public string Password { get; set; }
public string SecurityQuestion { get; set; }
public string SecurityAnswer { get; set; }
public bool Valid { get; set; }
public IList<Subscription> Subscriptions { get; set; }
public bool MailMarketing { get; set; }
public bool PartnerMailMarketing { get; set; }
}
public class PostalAddress
{
public int ID { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string Address3 { get; set; }
public string City { get; set; }
public string Postcode { get; set; }
public string Region { get; set; }
public string Country { get; set; }
}

If a Customer have X suscriptions, every suscription should have the customerID so you need that in your Suscription class (public int CustomerID {get; set;}).
OTOH, I think that you have to put that Customer reference as virtual and the suscription one (I don't know why).
Maybe Im wrong but that works for me.
Anyway, what's your problem?

Your models look correct. You don't necessarily need the Customer property in the Subscription class, but it does help if you want to retrieve a specific Subscription and then want to find the customer that is tied to that subscription. In that instance you can then do var customer = mySub.Customer instead of querying for a customer with the specific subscription id.
