This is my code in modeview:-

public partial class DistriputeMultipleNotificatiponsViewModel
    {
        public virtual IEnumerable<ClientsNotifications> list { get; set; }
        public virtual DistrbuteTechToNotifi create { get; set; }
        public virtual ClientsNotifications displayname { get; set; }
        
    }

View:-

@model WebProject.Models.DistriputeMultipleNotificatiponsViewModel
@using WebProject.Models.BusinessLayer

@using App_GlobalResources;
@{
    ViewBag.Title = WhiteWhaleLanguage.Index;
}

@using (Html.BeginForm("SendMultipleNotificationToTechnical", "ClientsNotifications", FormMethod.Post))
{
    @Html.ValidationSummary()
    @Html.AntiForgeryToken()
    <div class="box box-DG">
        <div class="box-header">
            <span style="color:#2D69B7"></span>
            <h3 class="box-title">@WhiteWhaleLanguage.NotificationsList</h3>
        </div>
        <div class="box-body">
            <table id="example1" class="table table-bordered table-striped box-DG">
                <thead>

}

this is ActionResult in controller:-

public ActionResult SendMultipleNotificationToTechnical()
        {
            DistriputeMultipleNotificatiponsViewModel model = new DistriputeMultipleNotificatiponsViewModel();

            if(ModelState.IsValid)
            {
                string constr = ConfigurationManager.ConnectionStrings["WhiteWhaleModel"].ConnectionString;
                foreach (var id in model.list)
                {
                    using (SqlConnection con = new SqlConnection(constr))
                    {
                        string query = " INSERT INTO DistrbuteTechToNotifi(ClientsNotificationsID,LocationCenterID, CenterTechnicalID, VisiteDate, DistributeDate) ";
                        query = query + " VALUES(@ClientsNotificationsID,@LocationCenterID, @CenterTechnicalID, @VisiteDate, @DistributeDate); ";
                        query = query + " SELECT SCOPE_IDENTITY(); ";
                        using (SqlCommand cmd = new SqlCommand(query))
                        {
                            cmd.Connection = con;
                            con.Open();
                            cmd.Parameters.AddWithValue("@ClientsNotificationsID", model.create.ClientsNotifications.ID);
                            cmd.Parameters.AddWithValue("@LocationCenterID", model.create.LocationCenterID);
                            cmd.Parameters.AddWithValue("@CenterTechnicalID", model.create.CenterTechnicalID);
                            cmd.Parameters.AddWithValue("@VisiteDate", model.create.VisiteDate);
                            cmd.Parameters.AddWithValue("@DistributeDate", DateTime.UtcNow);
                            cmd.ExecuteNonQuery();
                            con.Close();
                        }

                        using (SqlConnection con2 = new SqlConnection(constr))
                        {
                            string query2 = " Update ClientsNotifications set StateID = 4 ";
                            query2 = query2 + " Where ID = @ClientsNotificationsID  ";
                            using (SqlCommand cmd2 = new SqlCommand(query2))
                            {
                                cmd2.Connection = con2;
                                con2.Open();
                                cmd2.Parameters.AddWithValue("@ClientsNotificationsID", model.create.ClientsNotificationsID);
                                cmd2.ExecuteNonQuery();
                                con2.Close();
                            }
                        }

                        return View("Index");
                    }
                }
            }

            return View(model);
        }
