int gr1 = 0;
int cr1 = int.Parse(TextBox1.Text);
var sel1 = (from cr in db.Credit2s
join hk in db.H_Kardanis on cr.CID equals hk.CreID
where cr.CID == gr1
where hk.CreID == cr1
select new { cr1, gr1 });

int gr2 = 0;
int cr2 = int.Parse(TextBox2.Text);
var sel2 = (from cr in db.Credit2s
join hk in db.H_Kardanis on cr.CID equals hk.CreID
where cr.CID == gr2
where hk.CreID == cr2
select new { cr2, gr2 });




if ((gr1 + gr2) > 6)
{

lblno.Visible = true;
lblno.Text = "??? ???? ?? ?????? ?? ??? 6 ???? ?? ?????";
}
