字符轉ASCII碼：

public static int Asc(string character)
  {
   if (character.Length == 1)
   {
    System.Text.ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding();
    int intAsciiCode = (int)asciiEncoding.GetBytes(character)[0];
    return (intAsciiCode);
   }
   else
   {
    throw new Exception("Character is not valid.");
   }

  }

 

ASCII碼轉字符：

public static string Chr(int asciiCode)
  {
   if (asciiCode >= 0 && asciiCode <= 255)
   {
    System.Text.ASCIIEncoding asciiEncoding = new System.Text.ASCIIEncoding();
    byte[] byteArray = new byte[] { (byte)asciiCode };
    string strCharacter = asciiEncoding.GetString(byteArray);
    return (strCharacter);
   }
   else
   {
    throw new Exception("ASCII Code is not valid.");
   }
  }
