ascii和字符串的相互转换

//字符串转ascii码
MessageBox.Show(System.Text.ASCIIEncoding.ASCII.GetBytes("A")[0].ToString());
//ascii转字符串
ASCIIEncoding AE2 = new ASCIIEncoding();

byte[] ByteArray2 = { 65, 97, 102 };
char[] CharArray = AE2.GetChars(ByteArray2);

for (int x = 0; x <= CharArray.Length - 1; x++)
{
MessageBox.Show(CharArray[x].ToString());
}
