C#“字符转成ASCII码,ASCII码转成字符”代码


Warning: Use of undefined constant g_prettify_esc_callback - assumed 'g_prettify_esc_callback' (this will throw an Error in a future version of PHP) in /home/wwwroot/dbci/wp-content/plugins/g-prettify/prettify.php on line 19

1.字符转换成对应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.");
}

}

2.ASCII码值转换成对应字符:

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.");
}
}

学习小结:字符转换成ASCII码函数:Encoding.ASCII.GetBytes(string)
将ASCII码转换成字符:Convert.ToString(Encoding.ASCII.GetString(asciicode))
