ASP.NET MVC Model binding not parsing - json

Question

I am having some problems getting my ASP.NET MVC application to parse my model, i simply just get "null".
This is my ASP.NET MVC action
public AdobeReturnSet<UserModel> Post([FromBody]UserModel model)
I have also tried without the [FromBody], that did not help.
This is my model
public class UserModel
{
public int AdobeId { get; set; }
[Required]
[StringLength(500)]
public string FristName { get; set; }
[Required]
[StringLength(500)]
public string LastName { get; set; }
[Required]
[StringLength(250)]
[EmailAddress]
public string Email { get; set; }
[Required]
public string OrganizationIdentification { get; set; }
public string Organization { get; set; }
public string OrganizationFull { get; set; }
}
And this is how i send the request
using (WebClient wc = new WebClient())
{
wc.Headers[HttpRequestHeader.Accept] = "application/json";
wc.Headers[HttpRequestHeader.AcceptCharset] = "utf-8";
wc.Headers[HttpRequestHeader.ContentType] = "application/json";
result = wc.UploadString(url, "POST", data);
}
The url is correct as the correct action is reached and this is the value of data:
{"AdobeId":0,"FristName":"Kasper Rune","LastName":"Søgaard","Email":"krus#arcanic.dk","OrganizationIdentification":null,"Organization":null,"OrganizationFull":null}
But when the request reaches my action is the model simply null.
It is a ApiController if that changes anything.

Looks like an encoding problem. Try using the UploadData method instead and use UTF-8 encoding:
using (var wc = new WebClient())
{
var data = Encoding.UTF8.GetBytes(#"{""AdobeId"":0,""FristName"":""Kasper Rune"",""LastName"":""Søgaard"",""Email"":""krus#arcanic.dk"",""OrganizationIdentification"":null,""Organization"":null,""OrganizationFull"":null}");
wc.Headers[HttpRequestHeader.Accept] = "application/json";
wc.Headers[HttpRequestHeader.ContentType] = "application/json";
byte[] result = wc.UploadData(url, "POST", data);
string json = Encoding.UTF8.GetString(result);
}
Alternatively you could use the new HttpClient:
using (var client = new HttpClient())
{
client.DefaultRequestHeaders.ConnectionClose = true;
var value = new
{
AdobeId = 0,
FristName = "Kasper Rune",
LastName = "Søgaard",
Email = "krus#arcanic.dk",
};
var result = client.PostAsJsonAsync(url, value).Result;
if (result.IsSuccessStatusCode)
{
string json = result.Content.ReadAsStringAsync().Result;
}
}
Also you might have a typo at FristName which should probably be FirstName.
