    [RESOLVED] String[] to Byte[] index by index please

    Okay, I have a text box for input, and from this text box I need to take the data and parse it out to bytes and send it to a controller card for processing. The input is temperature and should not be below 100 (this is not important right now). My main problem is I need byte[i] = string[i]; exactly. Not its byte value for the char that is represented. if string[i] = 2 I need byte[i] to = 2.

    Here is the code I have so far. I get values but not what I want, and it overwrites my byte and only fills 1 array slot.

    byte[] gen = new byte[5];
    char[] holder = setpointBoxQS.Text.ToCharArray();
    string[] conv = new string[holder.Length];

    for (int i = 0; i < holder.Length; i++)
    {
    conv[i] = holder[i].ToString();
    }

    if (holder.Length > 2)
    {
    for (int i = 0; i <= holder.Length; i++)
    {
    gen = Encoding.UTF8.GetBytes(conv[i]);
    }
    }


    Thanks for any help

    I got it working for what I want it to do, but I cant help feel there is an easier way to do this.


    byte[] gen = new byte[5];
    char[] holder = setpointBoxQS.Text.ToCharArray();
    string[] conv = new string[holder.Length];
    int[] iconv = new int[holder.Length];

    for (int i = 0; i < holder.Length; i++)
    {
    conv[i] = holder[i].ToString();
    }

    if (holder.Length > 2)
    {
    for (int i = 0; i < holder.Length; i++)
    {
    iconv[i] = Convert.ToInt32(conv[i]);
    gen[i] = (byte)iconv[i];
    }
    }

    Re: String[] to Byte[] index by index please

    This is what I came up with but I'm unhappy with all the conversions going on
    Code:
                const int GEN_SIZE = 5;
                string text = setpointBoxQS.Text;
    
                byte[] gen = new byte[GEN_SIZE];
                char[] holder = text.ToCharArray();
    
                for (int i = 0; i < holder.Length; i++)
                {
                    //Process a full gen array
                    if (i % GEN_SIZE == 0 &&
                        i != 0)
                    {
                        //Our gen array is complete
                        //*** Do something with it
                    }
    
                    int byteValue = Convert.ToInt32(Convert.ToString(holder[i]));
                    gen[i % GEN_SIZE] = (byte)byteValue;
                }
