How to Convert String to ASCII Format and ASCII Format to String Format in C#
string a = "abc";
byte[] asciiBytes = Encoding.ASCII.GetBytes(a);

{
int b = asciiBytes[i]; // string to ascii value
string sssss = ((char)b).ToString(); // ascii value to string
}
byte[] asciiBytes = Encoding.ASCII.GetBytes(a);
for (int i = 0; i < a.Length; i++)
{
int b = asciiBytes[i]; // string to ascii value
string sssss = ((char)b).ToString(); // ascii value to string
