C#实现HSL颜色值转换为RGB的方法

//This method converts the values to RGBpublic RgbColor HslToRgb(int Hue, int Saturation, int Lightness){ double num4 = 0.0; double num5 = 0.0; double num6 = 0.0; double num = ((double)Hue) % 360.0; double num2 = ((double)Saturation) / 100.0; double num3 = ((double)Lightness) / 100.0; if (num2 == 0.0) {  num4 = num3;  num5 = num3;  num6 = num3; } else {  double d = num / 60.0;  int num11 = (int)Math.Floor(d);  double num10 = d - num11;  double num7 = num3 * (1.0 - num2);  double num8 = num3 * (1.0 - (num2 * num10));  double num9 = num3 * (1.0 - (num2 * (1.0 - num10)));  switch (num11)  {   case 0:    num4 = num3;    num5 = num9;    num6 = num7;    break;   case 1:    num4 = num8;    num5 = num3;    num6 = num7;    break;   case 2:    num4 = num7;    num5 = num3;    num6 = num9;    break;   case 3:    num4 = num7;    num5 = num8;    num6 = num3;    break;   case 4:    num4 = num9;    num5 = num7;    num6 = num3;    break;   case 5:    num4 = num3;    num5 = num7;    num6 = num8;    break;  } } return new RgbColor((int)(num4 * 255.0), (int)(num5 * 255.0), (int)(num6 * 255.0));}//The structure that will hold the RGB Valuespublic struct RgbColor{ public RgbColor(int r, int g, int b) {  red = r;  green = g;  blue = b; } public int red; public int green; public int blue;}
