Show data according to condition sequence

I want to get it some filed using OrderBy condition but in my scenario orderby not working. In here my ProductSequence is int filed.

IList<ProViewModels> _newprd = iproRepository
    .GetList(x => x.ProductId.Equals(ProductId))
    .Select(x => new ProViewModels { ProductName = x.ProductName, DisplayName = x.DisplayName })
    .OrderBy(x=>x.ProOrder).ToList();
return _newprd ;
