获取随机颜色 [英] Get Random Color

问题描述

您知道生成随机颜色(不是随机颜色名称！)的任何方法吗?

Do you know any method to generate a random Color (not a random Color Name!)?

我已经有一个了，但是这个做得不好:

I've already got one, but this one is'nt doing it correctly:

这只会返回绿色:

Random r = new Random();
BackColor = Color.FromArgb(r.Next(0, 256), r.Next(0, 256), 0);

这只会返回红色:

Random r = new Random();
BackColor = Color.FromArgb(r.Next(0, 256), 0, 0);

这只会返回蓝色:

Random r = new Random();
BackColor = Color.FromArgb(0, 0, r.Next(0, 256));

我希望我的代码每次都返回一种随机的颜色，而不是每次返回绿色/红色/蓝色，就像上面的颜色一样.

I want my Code to return one, random Color, not only green/red/blue every time, as the above ones do.

如何解决这个问题?

任何建议都会得到批准！

这是我在删除然后取消删除您的问题之前开始发布的答案:

Here's the answer I started posting before you deleted and then un-deleted your question:

public partial class Form1 : Form
{
    private Random rnd = new Random();

    public Form1()
    {
        InitializeComponent();
    }

    private void button1_Click(object sender, EventArgs e)
    {  
        Color randomColor = Color.FromArgb(rnd.Next(256), rnd.Next(256), rnd.Next(256));

        BackColor = randomColor;
    }
}
