Question : C# How to remove <STX> and <ETX> characters from file

Hello,

I have an ascii file. And I read it to string.
Then I need to remove <STX> and <ETX> characters from file. But how to do it?

         
          CopyFileToStr("Lala.a00");

            //remove('\r');
            HexFileString.Remove(HexFileString.IndexOf(),1);
            HexFileString.Remove(HexFileString.IndexOf('\ '),1);

Answer : C# How to remove <STX> and <ETX> characters from file

Are they actually the control characters #2 and #3 at the beginning and end? (and not literally "STX" or "ETX")
http://en.wikipedia.org/wiki/Control_character

If so, try something like:

                       
             string filename = "Lala.a00";
string data = System.IO.File.ReadAllText(filename).TrimStart(new char[] {Convert.ToChar(2)}).TrimEnd(new char[] {Convert.ToChar(3)});
System.IO.File.WriteAllText(filename, data);
