我得到了错误
cannot implicity convert type 'System.Linq.IQueryable<EntityNetimoveis.San_Imovel>' to 'EntityNetimoveis.San_Imovel' An Explicit conversion exists (are you missing a cast ?)
当我尝试以下代码时会发生这种情况
EntityNetimoveis.San2011Entities db = new EntityNetimoveis.San2011Entities();
EntityNetimoveis.San_Imovel im = db.San_Imovel.Where(a => a.Credenciada_Id == 10);
我必须进行哪种类型的转换?
