        {
            UsbBorrow Stu = null;

            using (AssetEntities db = new AssetEntities())
            {
                Stu = db.UsbBorrow.Where(W => W.ID == id).FirstOrDefault();
            }
                return View(Stu);
        }
        [HttpPost]
        public ActionResult Edit(UsbBorrow usb)
        {
            using (AssetEntities db = new AssetEntities())
            {
                var EditStu = db.UsbBorrow.Attach(usb);
                EditStu.申请单号 = usb.申请单号;
                EditStu.规格 = usb.规格;
                EditStu.编号 = usb.编号;
                EditStu.工号 = usb.工号;
                EditStu.姓名 = usb.姓名;
                EditStu.领用日期 = usb.领用日期;
                EditStu.归还日期 = usb.归还日期;
                EditStu.Empty = usb.Empty;
                EditStu.Antivirus = usb.Antivirus;
                EditStu.备注 = usb.备注;
                db.Entry(EditStu).Property(P => P.申请单号).IsModified = true;
                db.Entry(EditStu).Property(P => P.规格).IsModified = true;
                db.Entry(EditStu).Property(P => P.编号).IsModified = true;
                db.Entry(EditStu).Property(P => P.工号).IsModified = true;
                db.Entry(EditStu).Property(P => P.姓名).IsModified = true;
                db.Entry(EditStu).Property(P => P.领用日期).IsModified = true;
                db.Entry(EditStu).Property(P => P.归还日期).IsModified = true;
                db.Entry(EditStu).Property(P => P.Empty).IsModified = true;
                db.Entry(EditStu).Property(P => P.Antivirus).IsModified = true;
                db.Entry(EditStu).Property(P => P.备注).IsModified = true;
                db.Configuration.ValidateOnSaveEnabled = false;
                db.SaveChanges();
                db.Configuration.ValidateOnSaveEnabled = true;

            }
            return RedirectToAction("AssetList");
        }

求大神帮忙补上删除一行数据的代码，删除完成后重定向到AssetList

 public ActionResult Delete(int id)

public ActionResult Delete(int id)
{
using (AssetEntities db = new AssetEntities())
{
db.UsbBorrow.Remove(db.UsbBorrow.Single(x => x.id == id));
db.SaveChanges();
}
}
