产生随机颜色

代码 1 1. public string GetRandomColor()
2 2. {
3 3. Random RandomNum_First = new Random((int)DateTime.Now.Ticks);
4 4. // 对于C#的随机数，没什么好说的
5 5. System.Threading.Thread.Sleep(RandomNum_First.Next(50));
6 6. Random RandomNum_Sencond = new Random((int)DateTime.Now.Ticks);
7 7.
8 8. // 为了在白色背景上显示，尽量生成深色
9 9. int int_Red = RandomNum_First.Next(256);
10. int int_Green = RandomNum_Sencond.Next(256);
11. int int_Blue = (int_Red + int_Green > 400) ? 0 : 400 - int_Red - int_Green;
12. int_Blue = (int_Blue > 255) ? 255 : int_Blue;
13.
14. return Color.FromArgb(int_Red, int_Green, int_Blue).Name;
15. }
