byte[] 转成32进制 C#

在 C# 中将 byte 数组转换为32进制可以使用以下方法：

public static string ConvertToBase32(byte[] bytes)
{
    const string base32Chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ234567";
    StringBuilder result = new StringBuilder();

    int bitCount = 0;
    int currentByte = 0;

    foreach (byte b in bytes)
    {
        currentByte = (currentByte << 8) | b;
        bitCount += 8;

        while (bitCount >= 5)
        {
            int index = (currentByte >> (bitCount - 5)) & 0x1F;
            result.Append(base32Chars[index]);
            bitCount -= 5;
        }
    }

    if (bitCount > 0)
    {
        int index = (currentByte << (5 - bitCount)) & 0x1F;
        result.Append(base32Chars[index]);
    }

    return result.ToString();
}

使用示例：

byte[] byteArray = { 0x12, 0x34, 0x56, 0x78, 0x9A, 0xBC, 0xDE, 0xF0 };
string base32String = ConvertToBase32(byteArray);
Console.WriteLine(base32String);

这将输出转换后的32进制字符串。
