How to get Token from DotNetOpenAuth OAuthAuthorizationServer sample with C#?

Question

How to get Token from DotNetOpenAuth OAuthAuthorizationServer sample with C#? I'm running the sample provided in Github. I want to get the token, for now unsuccessfull. Always get a 400, bad request. The request I've sending is as follows:

var request = WebRequest.CreateHttp("http://localhost:50172/OAuth/Token");
        request.Method = "POST";
        request.ContentLength = 0;
        request.Headers.Add("client_id", "sampleconsumer");
        request.Headers.Add("client_secret", "samplesecret");
        request.Headers.Add("grant_type", "authorization_code");
        request.Headers.Add("code", "teste");
        request.Headers.Add("redirect_uri", "");

        WebResponse response = null;

        try
        {
            response = request.GetResponse();
        }
        catch (Exception ex)
        {
            //400 -  bad request here.
        }

I have no skills with OAuth, this is my first attempt. I've searched a lot but still a bit confuse.

First you need to set redirect uri and 2cnd you sure that you want to send this request to localhost? And your try catch stuff makes no complete sense - use response.ensuresuccess() method in the try block — Matthias Herrmann

I'll set redirect uri a try it again. And yes, I'm using localhost for tests purpose only. Thank you. — ramires.cabral

Do not use headers for the ClientID and the other stuff, put it into the body.

This is how I get Token with the Client Credential Grant:

using Newtonsoft.Json;

...
var url = "http://localhost:50172/OAuth/Token"
var request = WebRequest.Create(url);
request.Method = "POST";

string data = "grant_type=client_credentials&client_id=" +
    "sampleconsumer&client_secret=samplesecret";
request.ContentType = "application/x-www-form-urlencoded";
byte[] dataStream = Encoding.UTF8.GetBytes(data);
request.ContentLength = dataStream.Length;
Stream newStream = request.GetRequestStream();

newStream.Write(dataStream, 0, dataStream.Length);
newStream.Close();

WebResponse response = request.GetResponse();
using (var reader = new StreamReader(response.GetResponseStream()))
{
    string result = reader.ReadToEnd();
    accessToken = JsonConvert.DeserializeObject<AccessToken>(result);
}
