C# LINQ而不是嵌套的foreach和if

有人知道以下代码的Linq代码是什么吗

foreach (Bed bed in field.GetBeds())
{
    foreach (Asparagus asparagus in bed.GetAsparaguses())
    {
        if (asparagus.Time.Date == day.Date && asparagus.Harvested)
        {
            count++;
        }
    }
}

通过

选择many

获取所有芦笋，根据

中的条件过滤芦笋，然后
计数
结果

field.GetBeds()
     .SelectMany(bed => bed.GetAsparaguses())
     .Where(asparagus => asparagus.Time.Date == day.Date && asparagus.Harvested)
     .Count();

     .Where(asparagus => asparagus.Time.Date == day.Date && asparagus.Harvested)
     .Count();

诀窍是使用
SelectMany
将嵌套项展平

var count = field.BetBeds()
    .SelectMany(bed => bed.GetAsparaguses())
    .Where(asparagus => asparagus.Time.Date == day.Date && asparagus.Harvested)
    .Count();
