c# 之如何計算md5碼

代碼如下：

    static MD5 s_md5;

    static MD5 MD5Obj => s_md5 ??= MD5.Create();
    
    
    public static string ComputeHash(byte[] buffer)
    {
        if (buffer == null || buffer.Length < 1)
            return "";

        byte[] hash = MD5Obj.ComputeHash(buffer);
        StringBuilder sb = new StringBuilder();

        foreach (var b in hash)
            sb.Append(b.ToString("x2"));

        return sb.ToString();
    }
    
    public static string ComputeHash(string str)
    {
        byte[] buffer = Encoding.UTF8.GetBytes(str);
        return ComputeHash(buffer);
    }
