WPF color、brush、string转换

1、color转为brush：

Brush br = new SolidColorBrush(Color.FromRgb(0，0，0)); 

2、string转Color

(Color)ColorConverter.ConvertFromString((string)str);

3、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); 

4、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]);
}

5、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);  
 
}

6、将blend的 8位颜色值转为color

    /// 


    /// 将blend的8位颜色值转为color
    /// 
    /// 
    /// 
    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)
        };
    }
