Convert from string ascii to string Hex

Question

I need a function that convert this string to this string:

\"0x31 0x32 0x33          


        

Answer 1

Convert to byte array and then to hex

        string data = "1234";

        // Convert to byte array
        byte[] retval = System.Text.Encoding.ASCII.GetBytes(data);

        // Convert to hex and add "0x"
        data =  "0x" + BitConverter.ToString(retval).Replace("-", " 0x");

        System.Diagnostics.Debug.WriteLine(data);
