Linq error: Sequence contains no elements

这是一直报错的代码：

 

var supplier = (from s in ce.Suppliers where s.CreatedBy == HttpContext.Current.User.Identity.Name & !s.Status orderby 1 descending select s).First();

 

请使用.FirstOrDefault()

var supplier = (from s in ce.Suppliers where s.CreatedBy == HttpContext.Current.User.Identity.Name & !s.Status orderby 1 descending select s).FirstOrDefault();
