rgba转16进制: function RGBToHex(rgb){ var regexp = /[0-9]{0,3}/g; var re = rgb.match(regexp);//利用正则表达式去掉多余的部分,将rgb中的数字提取 var hexColor = "#"; var hex = ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'A', 'B', 'C', 'D', 'E', 'F']; for (var i = 0;

Faulty Odometer Time Limit: 20 Sec Memory Limit: 256 MB 题目连接 http://acm.hdu.edu.cn/showproblem.php?pid=4278 Description You are given a car odometer which displays the miles traveled as an integer. The odometer has a defect, however: it proceeds from
直接举例说明: int i = 15;//一个10进制数 string txt = Convert.ToString(i,16);//将上面10进制以16进制形式显示为f string s = "15";//一个字符串15 int i = Convert.ToInt32(s,16);//注意:这里并不是将15转换为16进制的F,而是将字符串“15”转为10进制的0x15这个数字,10进制为21; 讲一个字节数组转为16字节格式的字符串: string s = string.Empty;
