system.drawing.color 字符串转换 blend wpf 16进制转rgb argb color

1.由string的rgb数值"255,255,0"转换为color

{

              //string[]  color_params = e.Parameter.ToString().Split(',');
                //byte color_R = Convert.ToByte(color_params[0]);
                //byte color_G = Convert.ToByte(color_params[1]);
                //byte color_B = Convert.ToByte(color_params[2]);

}

2.由颜色名称字符串("black") 转化为color

 {

               ////ColorConverter c = new ColorConverter();
                ////object obj = c.ConvertFrom();
                ////Color color = (Color)obj;
                //Color color = Color.FromRgb(color_R, color_G, color_B);  

}

3.将blend的 8位颜色值转为color

/// <summary>

/// 将blend的8位颜色值转为color
        /// </summary>
        /// <param name="colorName"></param>
        /// <returns></returns>
        public Color ToColor(string colorName)
        {
            if (colorName.StartsWith("#"))
                colorName = colorName.Replace("#", string.Empty);
            int v = int.Parse(colorName, System.Globalization.NumberStyles.HexNumber);
            return new Color()
            {
                A = Convert.ToByte((v >> 24) & 255),
                R = Convert.ToByte((v >> 16) & 255),
                G = Convert.ToByte((v >> 8) & 255),
                B = Convert.ToByte((v >> 0) & 255)
            };
        }
