如何生成若干包括（）在一個倉庫

Question

我有一個Customer類運行時客戶可以有幾個Address

在我的倉庫我有這樣的：

protected DbSet<T> Table; 

而且這種方法：

public T Find<TIncludeField>(Expression<Func<T, bool>> where, 
    Expression<Func<T, TIncludeField>> include) 
    => Table.Where(@where).Include(include).FirstOrDefault(); 

然後我可以像這樣使用它：

_customerRepo.Find(x => x.Reference.ToLower() == reference.ToLower(), x => x.Addresses); 

我希望能夠做到這一點：

public T Find<TIncludeField>(Expression<Func<T, bool>> where, 
    Expression<Func<T, ICollection<TIncludeField>>> includes) 
    => Table.Where(@where).Include(includes).FirstOrDefault(); 

但我不知道如何在運行時創建的.Include(includes)

任何想法名單？

Answer 1

你可以試試這個擴展方法

public static IQueryable<T> IncludesAll<TIncludeField>(this IQueryable<T> query, 
IEnumerable<Expression<Func<T, TIncludeField>>> includes) 
{ 
    foreach (var include in includes) 
    { 
     query = query.Include(include); 
    } 

    return query; 
} 

Answer 2

我建議使用這一個（這將讓你包括不同類型的屬性，參數陣列允許你指定零，一個或多個包括）

public static IQueryable<T> IncludesAll<T>(this IQueryable<T> query, 
params Expression<Func<T, object>>[] includes) 
{ 
    foreach (var include in includes) 
    { 
     query = query.Include(include); 
    } 

    return query; 
}
