C# Convert a string to ASCII bytes

Question

I have a string:

LogoDataStr = \"ABC0000\"

I want to convert to ASCII bytes and the result should be:

LogoDataBy[0] = 0x41;         


        

Answer 1

Just throwing:

Encoding.ASCII.GetBytes("ABC0000").Dump();

Into LinqPAD gives an output of (decimal):

Byte[] (7 items)
65
66
67
48
48
48
48

So I'm not sure how you're getting 0x00...

Answer 2

This code

class Program
{
    static void Main(string[] args)
    {
        byte[] LogoDataBy = ASCIIEncoding.ASCII.GetBytes("ABC000");
    }        
}

produces expected output

Double check your code and the value of the string before you read ASCII bytes.

Answer 3

    class CustomAscii
    {
        private static Dictionary<char, byte> dictionary;

        static CustomAscii()
        {
            byte numcounter = 0x30;
            byte charcounter = 0x41;
            byte ucharcounter = 0x61;
            string numbers = "0123456789";
            string chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
            string uchars = "abcdefghijklmnopqrstuvwxyz";
            dictionary = new Dictionary<char, byte>();
            foreach (char c in numbers)
            {
                dictionary.Add(c, numcounter++);
            }
            foreach (char c in chars)
            {
                dictionary.Add(c, charcounter++);
            }
            foreach (char c in uchars)
            {
                dictionary.Add(c, ucharcounter++);
            }
        }

        public static byte[] getCustomBytes(string t)
        {
            int iter = 0;
            byte[] b = new byte[t.Length];
            foreach (char c in t)
            {
                b[iter] = dictionary[c];
                //DEBUG: Console.WriteLine(b[iter++].ToString());
            }

            return b;
        }
    }

This is how i would do it. JUST IF Encoding.ASCII.GetBytes() would return wrong values.
