How login toTwitter authentication and Twitter Synchronize in MVC and C#

 Twitter Syn in MVC and C#

Step1: create application in twitter by using this link https://dev.twitter.com/apps/new  once open that will display window like this after Create you will get 
1.ConsumerKey
2. ConsumerSecret
3.AccessTokenSecret
4. AccessTokenSecret

Use above keys from Below code..

Step2 : Use Keys in to you projects
Appurls.cs

public static string authentication = "https://api.twitter.com/oauth2/token";
public const string RequesttokenURL = "https://api.twitter.com/oauth/request_token";
public const string AuthorizeURL = "https://api.twitter.com/oauth/authorize";
public const string AccesstokenURL = "https://api.twitter.com/oauth/access_token";
public static string ConsumerKey="Your ConsumerKey ";
public static string ConsumerSecret="Your ConsumerSecret";
public static string AccessToken="Your AccessToken";
public static string AccessTokenSecret = "Your AccessTokenSecret ";
public static string TwitterAccountCredentialsURL = "https://api.twitter.com/1.1/account/verify_credentials.json";
public static string TwitterCallbackURL = " Your Return URL";


step3: Add one class name- oAuth.cs and write below code

Class Files for Twitter Access

Step5: Design your page and write your code Like this
Registration.cs

using System.Xml;
using System.Net.Mail;
using System.Net;
using Twilio;
using System.Drawing.Imaging;
using System.Collections.Specialized;
using System.Security.Cryptography;
using System.Text;
using oAuthExample;
using Laysous.Cinetot.WebAPP.App_Data;
public ActionResult Index()
{
GetUserDetailsFromTwitter();
}
private void GetUserDetailsFromTwitter()
        {
            if (Request["oauth_token"] != null & Request["oauth_verifier"] != null)
            {
                var oAuth = new oAuthTwitter();
                //Get the access token and secret.
                oAuth.AccessTokenGet(Request["oauth_token"], Request["oauth_verifier"]);
                if (oAuth.TokenSecret.Length > 0)
                {
                    url = AppUrls.TwitterAccountCredentialsURL;
                    xml = oAuth.oAuthWebRequest(oAuthTwitter.Method.GET, url, String.Empty);
                    JObject o = JObject.Parse(xml);
                    name = Convert.ToString(o["name"]);
                    username = Convert.ToString(o["screen_name"]);
                    profileImage = Convert.ToString(o["profile_image_url"]);
                    followersCount = Convert.ToString(o["followers_count"]);
                    noOfTweets = Convert.ToString(o["statuses_count"]);
                    recentTweet = Convert.ToString(o["status"]["text"]);
                    verified = Convert.ToString(o["verified"]);
                    id = Convert.ToString(o["id"]);
                    Session["verified"] = verified;
                    Session["id"] = id;
                    Response.Write("<script>window.close();</script>");
                }
            }
        }


step 6: you will get repose above code if u want display u can display your view page...
