将颜色代码转换成C#中的Color

    public Color ToColor(string color)
    {

        int red, green, blue = 0;
        char[] rgb;
        color = color.TrimStart('#');
        color = Regex.Replace(color.ToLower(), "[g-zG-Z]", "");
        switch (color.Length)
        {
            case 3:
                rgb = color.ToCharArray();
                red = Convert.ToInt32(rgb[0].ToString() + rgb[0].ToString(), 16);
                green = Convert.ToInt32(rgb[1].ToString() + rgb[1].ToString(), 16);
                blue = Convert.ToInt32(rgb[2].ToString() + rgb[2].ToString(), 16);
                return Color.FromArgb(red, green, blue);
            case 6:
                rgb = color.ToCharArray();
                red = Convert.ToInt32(rgb[0].ToString() + rgb[1].ToString(), 16);
                green = Convert.ToInt32(rgb[2].ToString() + rgb[3].ToString(), 16);
                blue = Convert.ToInt32(rgb[4].ToString() + rgb[5].ToString(), 16);
                return Color.FromArgb(red, green, blue);
            default:
                return Color.FromName(color);

        }
    }
