Edit - 5/5 Additional Information:
Here is my updated code for my actual project. I can now see that I am getting data if I restrict the parameters to a single result. but when I increase the results I can't get the foreach to work correctly. I have had to hardcode the array values. I appreciate any help in getting this working!!

Original post:
I am using this sample to try and get an SSIS package to consume from an API. I was unable to get my JSON to work (and the API used in the sample has moved so I was unable to get it to work "as is") so I decided to try with something easy.
https://dennysjymbo.blogspot.com/2014/03/utilizing-net-40-datacontractjsonserial.html?showComment=1493916532059#c208608008820233205

this is the line that is not working correctly:
jsonResponse = (RootObject)sr.ReadObject(responseStream);
In the image you can see that it added a people object but none of the data is there.
I would appreciate any help in figuring out what I need to modify in order to get the data in the response object.
Thanks!
Edit:
The actual error message that the ssis package gives is:
Error: 0x1 at Data Flow Task, Error Getting Data From Webservice!: System.NullReferenceException: Object reference not set to an instance of an object.
at ScriptMain.CreateNewOutputRows() in c:\Users\E37026\AppData\Local\Temp\Vsta\747a4fee6a1f4610a91610400e06a1ac\main.cs:line 81

Couple things here. First your url should be http://swapi.co/api/people/1/?format=json. Second is that you are not getting an array of people back, so you need to change this to a single object. Third the serializer doesn't like the datetime values, I changed them to strings and it worked. You can work on changing this in the staging area or in a derived column transform. Here is the code:

RestSharp query returning NotFound

This is my first usage of RestSharp
I am trying to connect to HubSpot using their FormsAPI (https://legacydocs.hubspot.com/docs/methods/forms/submit_form)
Using .Net, C#, MVC.
When I run in Fiddler, it works.
Here is my C# code, when I run it, I get a StatusCode of "NotFound". I am sure it is something simple I am missing?
var client = new RestClient("https://api.hsforms.com");
var request = new RestRequest("submissions/v3/integration/submit/{PortalId}/{formGuid}", Method.POST);
request.AddUrlSegment("portalId", "[myportalid]");
request.AddUrlSegment("formGuid", "[myformid]");
request.AddQueryParameter("hapikey", "[myapikey]");
request.RequestFormat = DataFormat.Json;
request.AddParameter("firstname", "testfirstname");
request.AddParameter("lastname", "testlastname");
request.AddParameter("email", "testemail#emailaddress.com");
request.AddParameter("business_unit", "Test");

It is better to create model of c# class and serialize it to Json and send POST request.
Example of RestSharp request
public async Task SendHubSpotRequest()
{
var PortalId = 1;
var formGuid = 1;

How make dropdownlist to access data on your SelectItemList using asp.net mvc?

I am using DropDownlist in order to get country of all the world. I have attached the file(country_list.txt) using srcFilePath. The error i am getting is "There is no ViewData item of type 'IEnumerable' that has the key 'SelectedCountryId'.What could be an issue, because my EditFormTrainingRegViewModel does have this field SelectedCountry as a primary key. Its been declared as public int? SelectedCountryId {get;set;}
// List for countries.
private IEnumerable<SelectListItem> GetCountryList()
{
SelectList listcn = null;
try
{
var list = this.LoadData().Select(p => new SelectListItem
{

Text = p.Country_Name
});
listcn = new SelectList(list, "Value", "Text");
}catch(Exception ex)

throw ex;
}
return listcn;
}

Deserialize multi-part JSON with DataContractJsonSerializer

I'm fairly new to the awesomeness that is JSON - I'm using the DataContractJsonSerializer. I cannot get the multiple instances of the Customer objects into the list.
The Attributes work as expected but there are no Customer objects in my List..??
{
"#attributes":
{"count":"2",
"offset":"0",
"limit":"100"
},
"Customer":
{
"firstName":"cust ",
"lastName":"one",
"title":"Owner",
"company":"CustOne Plants",
"companyRegistrationNumber":"",
"vatNumber":"",
"creditAccountID":"1",
"customerTypeID":"4",
"discountID":"0",
"taxCategoryID":"0",
"customerID":"1",
"createTime":"2017-06-19T23:36:11+00:00",
"timeStamp":"2017-06-20T18:55:11+00:00",
"archived":"false"
}
"Customer":
{
"firstName":"cust ",
"lastName":"two",
"title":"Owner",
"company":"CustTwo House of Games",
"companyRegistrationNumber":"",
"vatNumber":"",
"creditAccountID":"1",
"customerTypeID":"4",
"discountID":"0",
"taxCategoryID":"0",
"customerID":"1",
"createTime":"2017-06-19T23:36:11+00:00",
"timeStamp":"2017-06-20T18:55:11+00:00",
"archived":"false"
}
}
.NET code:
StreamReader stream = new StreamReader(#"C:\TMC Projects\PotteryManufacturing\CustomerJSON.txt");
string text = stream.ReadToEnd();
stream.Close();
byte[] byteArray = Encoding.UTF8.GetBytes(text);
MemoryStream stream1 = new MemoryStream(byteArray);
DataContractJsonSerializer serializer = new DataContractJsonSerializer(typeof(CustomersRoot));
var varInfo = serializer.ReadObject(stream1) as CustomersRoot;
stream1.Close();
and finally my classes/data contracts/data members:
[DataContract]
public class CustomersRoot
{
private List<Customer> m_Customers;
public CustomersRoot() { this.Customer = new List<Customer>(); }
[DataMember(Name ="#attributes")]
public Attributes attrs { get; set; }
[DataMember(Name = "Customer")]
public List<Customer> Customer
{
get { return m_Customers; }
set { m_Customers = value; }
}
}
[DataContract]
public class Customer
{
[DataMember(Name ="firstName")]
public string firstName { get; set; }
[DataMember(Name = "lastName")]
public string lastName { get; set; }
[DataMember(Name = "title")]
public string title { get; set; }
[DataMember(Name = "company")]
public string company { get; set; }
[DataMember(Name = "companyRegistrationNumber")]
public string companyRegistrationNumber { get; set; }
[DataMember(Name = "vatNumber")]
public string vatNumber { get; set; }
[DataMember(Name = "creditAccountID")]
public int creditAccountID { get; set; }
[DataMember(Name = "customerTypeID")]
public int customerTypeID { get; set; }
[DataMember(Name = "discountID")]
public int discountID { get; set; }
[DataMember(Name = "taxCategoryID")]
public int taxCategoryID { get; set; }
[DataMember(Name = "customerID")]
public int customerID { get; set; }
[DataMember(Name = "createTime")]
public string createTime { get; set; }
[DataMember(Name = "timeStamp")]
public string timeStamp { get; set; }
[DataMember(Name = "archived")]
public bool archived { get; set; }
}
[DataContract]
public class Attributes
{
[DataMember(Name = "count")]
public int count { get; set; }
[DataMember(Name = "offset")]
public int offset { get; set; }
[DataMember(Name = "limit")]
public int limit { get; set; }
}

I figured out what's going on here - the call can sometimes return an array of Customer objects (not formatted correctly above) OR a single instance of the object. When the web service returns a single Customer instance, the List code does not work. I will have to check on how to deal w/ this issue.

return obj;

public AllAnnotatedData Deserializer(string json)
{
