}

Controller:

public ActionResult Create(REVIEW r)
{

ProductDataDataContext db = new ProductDataDataContext();
db.REVIEWs.InsertOnSubmit(r);
db.SubmitChanges();
return RedirectToAction("Create");

}

This is my code for insert data using Linq,

After inserting that data will be display same page,

I am getting error like this
