在通过数据进行排位时排出栏?
原标题:Making list columns while looping through data?

我总是想问这个问题。 请在C# I ve got a IE amountable<Cars>中说,其中载有从LINQ查询到我的KQ数据库的20个结果。

我想用<代码>ul标签将其分为五栏。 我通常做的是,首先从<代码>ul开始,然后是foreach。 通过电子数字,在<代码>% 5 = 0时保持对应。 贴上<条码>/代码>,并在<条码>后启动新的一条。

是否有更好的办法这样做?

您可使用groupBy()将汽车与你想要介绍的汽车组合起来,在您的情形下,共有5辆汽车(如使用冷凝车,指数0至4的汽车将分为1组,指数5至9,第2组)。

 List<Car> cars = new List<Car>();
 //populate cars

 var carGroups = cars.Select((car, index) => new { Index = index, Car = car })
                     .GroupBy(x => x.Index / 5)
                     .Select(g => g.Select(x => x.Car).ToList())
                     .ToList();

    foreach (var group in carGroups)
    {
        //Emit <UL>
        foreach (var car in group)
        {
            //Emit <LI> with car details
        }
        //Emit </UL>
    }
