c#怎样把字符串转换为ASCII码

比如string a="大家好!"怎样才能把这个字符串转换成22823,23478,22909,33这样的ascii码呢? 请高手指教

Answer 1

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.");
}
}

Answer 2

string a = "大家好!";nt asc;for (i = 0; i < a.Length; i++)
asc = Convert.ToInt32(a[i]);
