Getting parameter_rejected error in quickbook online integration

I have done this code:
static void Main (string[] args)
{
Console.WriteLine("Authenticating..");
string consumerkey = "L0ORES0pf0uEody1YDI3sTkTpyBGaDVVnVRBb1krprkrghPWLQ";
string consumerSecret = "NAONcYrwGgpkFCJN2BgXZHjG8YLqn1JWMEPDXIMg";
string REQUEST_TOKEN_URL = "https://oauth.intuit.com/oauth/v1/get_request_token";
string ACCESS_TOKEN_URL = "https://oauth.intuit.com/oauth/v1/get_access_token";
string OauthLink = "https://developer.intuit.com/v2/OAuth2Playground/RedirectUrl";
var consumerContext = new OAuthConsumerContext
{
ConsumerKey = consumerkey,
ConsumerSecret = consumerSecret,
SignatureMethod = SignatureMethod.HmacSha1
};
IOAuthSession AuthSession = new OAuthSession(consumerContext,REQUEST_TOKEN_URL, OauthLink, ACCESS_TOKEN_URL);
IToken requestToken = AuthSession.GetRequestToken();
}
And I am getting error : An unhandled exception of type 'DevDefined.OAuth.Framework.OAuthException' occurred in DevDefined.OAuth.dll Additional information: parameter_rejected
I have attached screenshot of my error.

string HtmlResult = wc.UploadString(URI, myParameters);
wc.Dispose();
var jobject = JsonConvert.DeserializeObject<Test>(HtmlResult);
string accessToken = jobject.access_token;
string relmid = "123412341234123421341234"; // Relmid
OAuth2RequestValidator oauthValidator = new OAuth2RequestValidator(accessToken);

How to pass body data with UploadStringAsync C#

I'm trying pass a string in the body of my POST request using WebClient class. Below is my code:
protected void GetAccessToken(string client_id, string secret)
{
var urlEncodedSecret = HttpUtility.UrlEncode(secret);
var urlEncodedSid = HttpUtility.UrlEncode(client_id);
string bodyData = String.Format("grant_type=client_credentials&client_id=ms-app%3a%2f%2f{0}&client_secret={1}&scope=notify.windows.com", client_id, secret);
string address = "https://login.live.com/accesstoken.srf";
string myParameters = "param1=value1&param2=value2&param3=value3";
Uri URI = new Uri(address);
System.Net.WebClient webClient = new WebClient();
webClient.BaseAddress = address;
webClient.Headers["Content-Type"] = "application/x-www-form-urlencoded";
webClient.Headers["Content-Length"] = "211";
webClient.Headers["Host"] = "https://login.live.com";
webClient.UploadStringCompleted += new UploadStringCompletedEventHandler(uploadStringCompleted);
webClient.UploadStringAsync(URI, "POST", bodyData);
}
private void uploadStringCompleted(object sender, UploadStringCompletedEventArgs e)
{
string json = e.Result.ToString();
_oAuthToken = GetOAuthTokenFromJson(json);
}
When i run the application, i received the exception "The remote server returned an error: NotFound.".
I succeeded to make the same request using the Postman:
Anyone know something wrong about my request? Or something that puting me on a right way!?
