所以只有一个颜色的五个按钮，每种颜色都有编号1-5。

So I have this grid containing 5x5 buttons where I want to randomly generate one number(1-5) to each button, and randomly place one (of 5) color to each button.

Ex

[RED 1][BLUE 5][GREEN 2][RED 4][YELLOW 3]
[GREEN 1][YELLOW 5][Orange 3] and so on.....

Ok, so the question is, in which steps should I think? And are there some good methods to use in this case? I''m starting from scratch....

I appreciate any help!

EDIT

So there will only exist five buttons of one color, and to each color there are numbered 1-5.

推荐答案

您需要的是生成0-24的随机排列，为每个按钮分配一个数字。然后使用数字％5将数字和数字/ 5分配到颜色列表中。

要有效地生成随机排列，请尝试：

What you need is to generate a random permutation of 0-24, assigning one number for each of the buttons. Then just use number % 5 to assign the number and number / 5 to index into the color list.
To efficiently generate the random permutation try this:

using System.Collections.Generic;
using System.Linq;

private Random Rand = new Random();  // OR use a fixed "seed" here for reproducability when testing
private List<int> RandPerm(int N)
{
  List<int> p = new List<int>(Enumerable.Range(0, N));
  for (int k = 2; k <= N; k++)
  {
    int r = (int)Math.Ceiling(k * Rand.NextDouble());
    --r;
    p[k - 1] = p[r];
    p[r] = k - 1;
  }
  return p;
}
