我正在将s1字符串数组转换为字节数组，然后将其发送到客户端。这是一台服务器。所以在客户端我想将字节数组转换回字符串数组。使用Byte.Parse我无法转换字符串s2。那么如何将s1字符串数组和s2字符串数组转换为字节数组。

我想将字节数组转换回字符串数组，然后将结果放在客户端。

它表示无法从{[1}}

的byte [] []转换为byte []

Answer 1

你想要的字节数取决于你的编码。但它会是这样的：

string myString = "hello";
byte[] bytes = Encoding.UTF8.GetBytes(myString);
string fromBytes = Encoding.UTF8.GetString(bytes);
Console.Write(myString == fromBytes);

试试这个

       static void Main(string[] args)
        {
            string[] s1 = { "5", "168", "789", "28", "29", "155" };
            byte[][] s1_byte = ToBytes(s1);
            string[] s1_out = ToString(s1_byte);
            DisplayBytes(s1_byte);
            string[] s2 = { "sdf", "dsfds", "233" };
            byte[][] s2_byte = ToBytes(s2);
            DisplayBytes(s2_byte);
            string[] s2_out = ToString(s2_byte);
        }
        static byte[][] ToBytes(string[] ascii)
        {
            byte[][] results = ascii.AsEnumerable().Select(x => Encoding.UTF8.GetBytes(x)).ToArray();
            return results;
        }
        static void DisplayBytes(byte[][] bytes)
        {
            for (int i = 0; i < bytes.LongLength; i++)
            {
                Console.WriteLine(string.Join(" ", new List<byte>(bytes[i]).Select(x => "0x" + x.ToString("x2")).ToArray()));
            }
        }
        static string[] ToString(byte[][] bytes)
        {
            List<string> results = new List<string>();
            for (int i = 0; i < bytes.LongLength; i++)
            {
                string newString = Encoding.UTF8.GetString(bytes[i]);
                results.Add(newString);
            }
            return results.ToArray();

        }

将string []转换为byte []并返回string []并显示它
