CONTROLLER

public ActionResult Index() {

        GroupRepository grouprepository = new GroupRepository();

        ViewData["Group"] = grouprepository.FindGroups();

        return View();

    }

<%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage" %>

<% foreach (Group i in ViewData["Group"] as List)

{ %>

" checked="checked" />

<% } %>

The thing is that it is not able to find group id and displaying the following error. What is the solution?

CS1061: 'System.Text.RegularExpressions.Group' does not contain a definition for 'int_GroupId' and no extension method 'int_GroupId' accepting a first argument of type 'System.Text.RegularExpressions.Group' could be found (are you missing a using directive or an assembly reference?)
