JavaScript改写成C#!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
是一个加密函数,现怎么改为C#,写成一个方法,在服务器端运行

<SCRIPT   language= "JavaScript ">
function   Encrypt(s)
{
var   k,   tmp,   tmpstr;
var   key_S   =   "43,54,75,2,687,43,65,43,4,23,34,65,43,8,33,33,54,3 ";
key   =   key_S.split( ", ");
tmpstr   =   " ";
k   =   0;
for(var   j   =   0;   j   <   s.length;   j++){
tmp   =   (s.charAt(j).charCodeAt()   ^   key[k].valueOf(Number));  
s_hex   =   tmp.toString(16);
while   (s_hex.length <2){
s_hex   =   '0 '   +   s_hex;
}
tmpstr   =   tmpstr   +   s_hex;
k++;
}
return   tmpstr.toUpperCase();
}


</SCRIPT>



------解决方案--------------------
public string Encrypt(string s)
{
int k = 0, tmp;
string tmpstr = " ";
string key_s = "43,54,75,2,687,43,65,43,4,23,34,65,43,8,33,33,54,3 ";
string[] key = key_s.Split( ', ');

for (int j = 0; j < s.Length; j++)
{
tmp = (s[j] ^ int.Parse(key[k]));
string s_hex = tmp.ToString( "X ");
while (s_hex.Length < 2)
{
s_hex = '0 ' + s_hex;
}
tmpstr = tmpstr + s_hex;
k++;
}
return tmpstr.ToUpper();
}

呵呵，转换字符串的时候没注意要转成16进制。呵呵
public string Encrypt(string s)
{
int k = 0, tmp;
string tmpstr = " ";
string key_s = "43,54,75,2,687,43,65,43,4,23,34,65,43,8,33,33,54,3 ";
string[] key = key_s.Split( ', ');

for (int j = 0; j < s.Length; j++)
{
tmp = (s[j] ^ int.Parse(key[k]));
tmpstr = tmpstr + tmp.ToString( "x ").PadLeft(2, '0 ');
k++;
}
return tmpstr.ToUpper();
}
