Input string was not in a correct format

[a7med14]

List<Byte> Pt_split(string plain)
        {
            List<Byte> pb = new List<Byte>();
            // Byte p;
            string p;
            int temp = 0;
            if (plain.Length % 2 != 0)
                plain = '0' + plain;
 
            for (int i = 0; i < plain.Length / 2; i++)
            {
                p = plain.Substring(temp, 2);
                pb.Add(Convert.ToByte(p));
                temp += 2;
            }

What is it that you're trying to do.

Instead of using int temp = 0; use double temp;
The error is possibly due to the function that you have divided temp by 2 and it may give a decimal value which is not taken by int function.
