Global.asax文件中加：Database.SetInitializer<StuInfoDBContext>(null);

using System.Data.Entity;
using Iweb.Areas.SiteInfo.Models;

namespace Iweb
{
// Note: For instructions on enabling IIS6 or IIS7 classic mode,
// visit http://go.microsoft.com/?LinkId=9394801 public class MvcApplication : System.Web.HttpApplication
{
protected void Application_Start()
{

Database.SetInitializer<StuInfoDBContext>(null);
AreaRegistration.RegisterAllAreas();

WebApiConfig.Register(GlobalConfiguration.Configuration);
FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
RouteConfig.RegisterRoutes(RouteTable.Routes);
}
}
