//color转为brush：
    Brush br = new SolidColorBrush(Color.FromRgb(0，0，0)); 
    //string转Color
    (Color)ColorConverter.ConvertFromString((string)str);

//Color转string((Color)value).ToString();
    string和Brush的转换
    Brush color = newSolidColorBrush((Color)ColorConverter.ConvertFromString((string)str));

//Brush转string

((Brush)value).ToString();
    //string转byte[]
    System.Text.UnicodeEncoding converter = newSystem.Text.UnicodeEncoding();

byte[] stringBytes = converter.GetBytes(inputString);

//byte[]转string

System.Text.UnicodeEncoding converter = newSystem.Text.UnicodeEncoding();

stringoutputString = converter.GetString(stringByte);

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)
                };
            }
