❔ How i can convert a js function to c#

g = Math.round(1E11 * Math.random()) + "";
f = function() {
    for (var v = [], w = 0; 64 > w;)
        v[w] = 0 | 4294967296 * Math.sin(++w % Math.PI);
    return function(y) {
        var z, D, E, H = [z = 1732584193, D = 4023233417, ~z, ~D]
            , F = []
            , x = unescape(encodeURI(y)) + "\u0080"
            , u = x.length;
        y = --u / 4 + 2 | 15;
        for (F[--y] = 8 * u; ~u;)
            F[u >> 2] |= x.charCodeAt(u) << 8 * u--;
        for (w = x = 0; w < y; w += 16) {
            for (u = H; 64 > x; u = [E = u[3], z + ((E = u[0] + [z & D | ~z & E, E & z | ~E & D, z ^ D ^ E, D ^ (z | ~E)][u = x >> 4] + v[x] + ~~F[w | [x, 5 * x + 1, 3 * x + 5, 7 * x][u] & 15]) << (u = [7, 12, 17, 22, 5, 9, 14, 20, 4, 11, 16, 23, 6, 10, 15, 21][4 * u + x++ % 4]) | E >>> -u), z, D])
