这段Java用JS怎么写或者用C#

public static byte[][] getBytes(int i, int i2, byte[] bArr, byte[] bArr2, int i3) throws Exception {
        byte[] digest;
        MessageDigest instance = MessageDigest.getInstance("md5");

                    bArr4[i6] = digest[i11];
                    i4--;
                    i11++;

            }
            if (i7 == 0 && i4 == 0) {

        }
        for (int i12 = 0; i12 < digest.length; i12++) {
            digest[i12] = 0;
        }
        return bArr5;
    }

Answer 1

function getBytes( let i , let i2, let[] barr, let[] ..... ){
//变量名类型全部改成 let 或者 用 var 来定义, 数组也一样
//判断这样都差不多

}
