C# 随机颜色的方法

          public string GetRandomColor()
         {

             Random RandomNum_First = new Random((int)DateTime.Now.Ticks);

             //  对于C#的随机数，没什么好说的

             System.Threading.Thread.Sleep(RandomNum_First.Next());

             Random RandomNum_Sencond = new Random((int)DateTime.Now.Ticks);

             //  为了在白色背景上显示，尽量生成深色

             int int_Red = RandomNum_First.Next();

             int int_Green = RandomNum_Sencond.Next();

             int int_Blue = (int_Red + int_Green > ) ?  :  - int_Red - int_Green;

             int_Blue = (int_Blue > ) ?  : int_Blue;
             Color color = Color.FromArgb(int_Red, int_Green, int_Blue);
             string strColor = "#" + Convert.ToString(color.ToArgb(), ).PadLeft(, '').Substring(, );
             return strColor;

         }
