摘要:ColorTranslator 類別 - 處理顏色轉換好幫手
從 HTML 色碼 轉成 Color 的蠢方法：
1: string strColor = "#F0F8FF";
2: MatchCollection mc = Regex.Matches(strColor, @"([0-9A-Fa-f]{2})");
3: 4: Color c = new Color();
5: if (mc.Count == 3)
6: {7: int r = Convert.ToInt32(mc[0].Groups[0].Value, 16);
8: int g = Convert.ToInt32(mc[1].Groups[0].Value, 16);
9: int b = Convert.ToInt32(mc[2].Groups[0].Value, 16);
10: c = Color.FromArgb(r, g, b); 11: }
使用 ColorTranslator 所提供的靜態方法 FromHtml()，果然輕鬆愉快許多：
1: string strColor = "#F0F8FF";
2: Color c = ColorTranslator.FromHtml(strColor);
MSDN Library 提及的注意事項：ColorTranslatorToHtml() method translates a Color structure to a string representation of an HTML color. This is the commonly used name of a color, such as "Red", "Blue", or "Green", and not string representation of a numeric color value, such as "FF33AA".
如果是 Color 轉成色碼話，ColorTranslator 提供的靜態方法 ToHtml()，很可惜就不能派上用場了。
1: Color c = Color.AliceBlue;2: string strColor = ColorTranslator.ToHtml(c);
3: // Output: AliceBlue
土法煉鋼法出現：
1: Color c = Color.AliceBlue;2: string cRGB = string.Format("#{0:X2}{1:X2}{2:X2}", c.R, c.G, c.B);
3: // Output: #F0F8FF
