How to Convert String to Byte Array?

Question

I am getting an error reading:

Cannot implicitly convert type \'String\' to \'Byte[]\'

I think \'byte[]\' is byte array - if it

Answer 1

You can try like this:

string str= "some string";
var bytes = System.Text.Encoding.UTF8.GetBytes(str);

And to decode:

var decodeString = System.Text.Encoding.UTF8.GetString(bytes);

Answer 2

Try this,

static byte[] GetBytes(string str)
{
    byte[] bytes = new byte[str.Length * sizeof(char)];
    System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
    return bytes;
}

n byte to string conversion

static string GetString(byte[] bytes)
{
    char[] chars = new char[bytes.Length / sizeof(char)];
    System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
    return new string(chars);
}

Credit to this answer.

Answer 3

    static void Main(string[] args)
    {
        string inputStr = Console.ReadLine();
        byte[] bytes = Encoding.Unicode.GetBytes(inputStr);
        string str = Encoding.Unicode.GetString(bytes);
        Console.WriteLine(inputStr == str); // true
    }
