1、Color.FromArgb(120,243,244,247) 　　先将F3,F4,F7转化为十进制数，再调用以上方法。 2、把F3 F4 F7转成10进制      然后用 Color.FromArgb 3、Color yourColor = Color.FromName("#F3F4F7"); 4、比较笨一点的办法：      string a="#F3F4F7";      new System.Drawing.Color.fromArgb(           System.int8.parse(a.substring(1,2),System.Globalization.NumberStyles.AllowHexSpecifier);           System.int8.parse(a.substring(3,2),System.Globalization.NumberStyles.AllowHexSpecifier);           System.int8.parse(a.substring(5,2),System.Globalization.NumberStyles.AllowHexSpecifier);      ); 5、Color color ＝Color.FromArgb（0xf3,0xf4,0xf7); 6、Public ForeColor As System.Drawing.Color = ColorTranslator.FromHtml("#F3F4F7") 7、System.Drawing.ColorConverter cc=new System.Drawing.ColorConverter();      return (System.Drawing.Color)cc.ConvertFromString(sHex);
