最大的價格與LINQ和表達

Question

我有GenericRepository與方法

public virtual IEnumerable<tentity> Get(
Expression<func<tentity, bool="">> filter = null, 
Func<iqueryable<tentity>, IOrderedQueryable<tentity>> orderBy = null, 
string includeProperties = "") 
{ 
    IQueryable<tentity> query = dbSet; 
    if (filter != null) 
    { 
    query = query.Where(filter); 
    } 
    foreach (var includeProperty in includeProperties.Split 
     (new char[] { ’,’ }, StringSplitOptions.RemoveEmptyEntries)) 
    { 
    query = query.Include(includeProperty); 
    } 
    if (orderBy != null) 
    { 
    return orderBy(query).ToList(); 
    } 
    else 
    { 
    return query.ToList(); 
    } 
} 

例如，我得到的產品：

var products = _database.ProductRepository.Get(
filter: d => d.Price == price.Value, 
orderBy: 
q => q.OrderBy(d => d.Name)); 

我如何獲得產品與最高出價？ （也許像d.Max(d => d.Price)）

Answer 1

嘗試使用LINQ：

var product = from p in products 
       where p.Price == products.Max(s => s.Price) 
       select p;
