 public ActionResult Login(LoginModel model, string returnUrl)

 public ActionResult Register()

 public ActionResult Register(RegisterModel model)

Convert Database Data to JSON Data

public string ConvertDataTabletoString()
         DataTable dt = new DataTable();
         using (SqlConnection con = new SqlConnection("Data Source=XXX;Initial Catalog=master;Integrated Security=true"))
               using (SqlCommand cmd = new SqlCommand("select id,name,age from employee", con))
                  SqlDataAdapter da = new SqlDataAdapter(cmd);
                  System.Web.Script.Serialization.JavaScriptSerializer serializer = new System.Web.Script.Serialization.JavaScriptSerializer();
                  List<Dictionary<string, object>> rows = new List<Dictionary<string, object>>();
                   Dictionary<string, object> row;
                               foreach (DataRow dr in dt.Rows)
                                    row = new Dictionary<string, object>();
                                    foreach (DataColumn col in dt.Columns)
                                         row.Add(col.ColumnName, dr[col]);
                                return serializer.Serialize(rows);

Note: You just replace datasource (XXX) then it will take data from your table and covert to JSON. 
Thanks for your comment.
