字符转 ASCII 码

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 码转字符

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."); } }
