仅显示一定数量的数组元素 [英] Display only a certain number of array elements

问题描述

你好。

我在razor mvc的asp.net工作。

我试图给一个html标签的类名，存储类名在数组中作为字符串。

我用foreach循环遍历数组，我确实工作，我得到了类，但问题是我的数组中有5个元素，我只需要尽可能多的类名我有的标签。

下面我会告诉你我的意思。



数字{0}和{1}是其他的东西。

Hello.
I am working in asp.net in razor mvc.
I am trying to give a class name to an html tag, the class name is stored in an array as a string.
I am looping through the array with a foreach and i does work, i get the class, but the problem is that i have 5 elements in my array and i only need as many class names as many html tags i have.
Below i will show you what i mean.

The number {0} and {1} are for something else.

   string[] liclasses = { "fc-orange", "fc-sky", "fc-red", "fc-green", "fc-per" };
foreach (string lic in liclasses)
       {
        html += string.Format("<li class=\"{2}\"><a href=\"{0}\" ><span>{1}</span>        </a></li>"
        , target, lbl, lic);
        }

正如我说的那样有效但是当我在ADMIN页面中创建一个菜单项时，它会生成菜单项的5个实例，我将向您展示它的外观。（我们有自己的CMS，我们在管理页面中创建所有内容，并在代码中自动添加它们） 。

我的尝试：



我唯一尝试过的是foreach循环。

我被困在这里。

As i said this works but when i create a menu item in the ADMIN page it makes 5 instances of the menu item i will show you down how it looks.(We have our own CMS and we create everything in the admin page and they are added automaticly in the code).

What I have tried:

The only thing i have tried is the foreach loop.
I am stuck here.

推荐答案

嗯，显而易见的事情就是这么做正在跳过那些你不需要的东西。但是那时你需要一个标准（在你的场景描述中并不明显）。

Well, the obvious thing to do it is skipping the ones you don't need. But then you need a criterion for that (it is not apparent in the description of your scenario).
