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

 1 1.由string的rgb数值"255,255,0"转换为color
 2 
 3 {
 4 
 5               //string[]  color_params = e.Parameter.ToString().Split(',');
 6                 //byte color_R = Convert.ToByte(color_params[0]);
 7                 //byte color_G = Convert.ToByte(color_params[1]);
 8                 //byte color_B = Convert.ToByte(color_params[2]);
 9 
10 }
11 
12 2.由颜色名称字符串("black") 转化为color
13 
14  {
15 
16                ////ColorConverter c = new ColorConverter();
17                 ////object obj = c.ConvertFrom();
18                 ////Color color = (Color)obj;
19                 //Color color = Color.FromRgb(color_R, color_G, color_B);  
20 
21 }
22 
23 3.将blend的 8位颜色值转为color
24 
25 /// <summary>
26 
27 /// 将blend的8位颜色值转为color
28         /// </summary>
29         /// <param name="colorName"></param>
30         /// <returns></returns>
31         public Color ToColor(string colorName)
32         {
33             if (colorName.StartsWith("#"))
34                 colorName = colorName.Replace("#", string.Empty);
35             int v = int.Parse(colorName, System.Globalization.NumberStyles.HexNumber);
36             return new Color()
37             {
38                 A = Convert.ToByte((v >> 24) & 255),
39                 R = Convert.ToByte((v >> 16) & 255),
40                 G = Convert.ToByte((v >> 8) & 255),
41                 B = Convert.ToByte((v >> 0) & 255)
42             };
43         }
