随机化3种颜色 [英] Randomize 3 Colors

问题描述

我正在制作Breakout Game，我希望积木获得随机的BackColor。
现在，我的积木充满了所有类型的颜色：红色，绿色，蓝色，黄色，粉红色和所有其他颜色。

I'm making a Breakout Game and I want the bricks to get a random BackColor. Right now I have the bricks getting filled with all type of colors: red, green, blue, yellow, pink and all others.

我想做什么

这就是我现在拥有的：

private Random rnd = new Random();

Color randomColor = Color.FromArgb(rnd.Next(256), rnd.Next(256), rnd.Next(256));

bricks[x, y].BackColor = randomColor;

我搜索并尝试了许多不同的方法，但没有任何效果！我觉得这可能很简单，但实际上并不能完全解决。我考虑过要列出这三种颜色的列表，然后尝试将列表随机化，但是没有成功！

I've searched and tried many different things and nothing has worked! I feel like this might be simple to do but somehow can't really get to it. I thought about making a list of the 3 colors and try randomizing the list but it didn't work out!

推荐答案

免责声明：我是新手（对C＃）。

Disclaimer: I'm a newbie (to C#).

private Random rnd = new Random();
Color[] colorArr = {Color.FromArgb(0, 0, 255), Color.FromArgb(255, 255, 0), Color.FromArgb(0, 255, 0)};
bricks[x, y].BackColor = colorArr[rnd.Next(colorArr.Length)];

（colorArr.Length编辑由 Corak ）

(colorArr.Length edit suggested by Corak)

使用数组存储将要选择的所有颜色。接下来，从数组中调用一个随机元素。

Uses an array to store all the colors from which one will be picked. Next, a random element is called from the array.
