問(wèn)題描述

我正在尋找一種將長(zhǎng)二進(jìn)制字符串轉(zhuǎn)換為十六進(jìn)制字符串的方法.

I'm looking for a way to convert a long string of binary to a hex string.

二進(jìn)制字符串看起來(lái)像這樣 "0110011010010111001001110101011100110100001101101000011001010110001101101011"

the binary string looks something like this "0110011010010111001001110101011100110100001101101000011001010110001101101011"

我嘗試過(guò)使用

hex = String.Format("{0:X2}", Convert.ToUInt64(hex, 2));

但這只有在二進(jìn)制字符串適合 Uint64 時(shí)才有效，如果字符串足夠長(zhǎng)則不會(huì).

but that only works if the binary string fits into a Uint64 which if the string is long enough it won't.

還有其他方法可以將二進(jìn)制字符串轉(zhuǎn)換為十六進(jìn)制嗎?

is there another way to convert a string of binary into hex?

謝謝

推薦答案

我剛剛把這個(gè)搞砸了.或許你可以以此為起點(diǎn)……

I just knocked this up. Maybe you can use as a starting point...

public static string BinaryStringToHexString(string binary)
{
    if (string.IsNullOrEmpty(binary))
        return binary;

    StringBuilder result = new StringBuilder(binary.Length / 8 + 1);

    // TODO: check all 1's or 0's... throw otherwise

    int mod4Len = binary.Length % 8;
    if (mod4Len != 0)
    {
        // pad to length multiple of 8
        binary = binary.PadLeft(((binary.Length / 8) + 1) * 8, '0');
    }

    for (int i = 0; i < binary.Length; i += 8)
    {
        string eightBits = binary.Substring(i, 8);
        result.AppendFormat("{0:X2}", Convert.ToByte(eightBits, 2));
    }

    return result.ToString();
}
