挑战,以下js函数能否转换成c#代码
$:function(str){
var c1, c2, c3, c4,c5=[-1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, -1, 62, -1, -1, -1, 63,52, 53, 54, 55, 56, 57, 58, 59, 60, 61, -1, -1, -1, -1, -1, -1, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, -1, -1, -1, -1, -1, -1, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, -1, -1, -1, -1, -1]
,

------解决方案--------------------不会 帮up
------解决方案--------------------貌似MD5
------解决方案--------------------何必转啊?你把功能和用途说一下,直接写一下不是更快?
------解决方案--------------------很显然是加密解密用途的,楼主不知道算法而已。
------解决方案--------------------做人要厚道!
