请问有没有人能够用C# 写一个函数跟这个javascript函数功能一样呢
function(l) {
var j = "";
var s, q, o = "";
var r, p, n, m = "";
var k = 0;
do {
s = l.charCodeAt(k++);
q = l.charCodeAt(k++);
o = l.charCodeAt(k++);
r = s >> 2;
p = ((s & 3) << 4) | (q >> 4);
n = ((q & 15) << 2) | (o >> 6);
m = o & 63;
if (isNaN(q)) {
n = m = 64
} else {
if (isNaN(o)) {
m = 64
}
}
j = j + keys.charAt(r) + keys.charAt(p);
s = q = o = "";
r = p = n = m = ""
} while ( k < l . length );
return j
｝


我的基础不太扎实，charat 跟 charcodeat 还有右移这些不熟。谢谢了！ 调试我可以。

不会是 base64吧？

C# code

        public string function(string l)        {            string keys = "ADFEWQTGSDFAEREWRW";            string j = string.Empty;            char s, q, o;            char r, p, n, m;            int k = 0;            while (k < l.Length)            {                s = l[k++];                q = l[k++];                o = l[k++];                r = (char)(s >> 2);                p = (char)(((s & 3) << 4) | (q >> 4));                n = (char)((((q & 15) << 2) | (o >> 6)));                m = (char)(o & 63);                if (char.IsNumber(q))                {                    n = m = (char)64;                }                else                {                    if (char.IsNumber(o))                    {                        m = (char)64;                    }                }                j = j + keys[r] + keys[p];                s = q = o = char.MinValue;                r = p = n = m = char.MinValue;            }            return j;        }
