Removing deserialization of the <struct> list

Question

Removing deserialization of the <struct> list

I am trying to deserialize from json to List<struct>, but my object is always null. The data types in the original JSON seem correct, and my code does not cause any errors, so I am completely fixated on why it does not work.

The class I'm deserting into:

public class SystemStatusRules
{
    public struct EmailItem 
    {
        public int EmailSubject_Id;
        public bool IsSubject;
        public string Email_String; 
        public int StatusCode;
    }
    public List<EmailItem> EmailItems {get; set;}
}

My JSON:

{"EmailItems":[
    {"EmailSubject_Id":16,"IsSubject":true,"Email_String":"Cube Build Successful","StatusCode":0},
    {"EmailSubject_Id":17,"IsSubject":true,"Email_String":"Cube Build Failure","StatusCode":0}
]}

and finally my deserialization code:

[HttpPost]
public bool SetAllStatusRules(string ruleList )
{
    SystemStatusRules subjectRules =
        JsonConvert.DeserializeObject<SystemStatusRules>(ruleList);
}

Just in case, if you need it, my code for serialization:

objArray.push({ EmailSubject_Id: SubjectId, IsSubject: IsSubject,
                Email_String: EmailSubject, StatusCode: status });
objArray = { EmailItems: objArray };
var rulesJSON = JSON.stringify(objArray);
$.ajax({
    url: "Management/SetAllStatusRules",
        type: 'POST',
        data: 'ruleList='+rulesJSON,
        success: function (result) {
            MyResultFunction(result);
      }
  });

Edit:

This is something to do with me, throwing at the object. The following code has a subjectRules variable that is correctly populated. However, ssr is null.

object subjectRules = JsonConvert.DeserializeObject<SystemStatusRules>(StatusRules);
SystemStatusRules ssr = (SystemStatusRules)subjectRules;

I don’t know what’s wrong, but deserializing in var allows me to use the data object as a workaround.
