byte[] Keybyte = new byte[Key.Length];
System.Text.ASCIIEncoding Encoding = new System.Text.ASCIIEncoding();
return Convert.ToBase64String(Encoding.GetBytes(Key) );
///// U can also use it to convert string to Bytes.
Short Method:
string OrderCode = “Ord12011982″;
#region Encode
byte[] Enc = ASCIIEncoding.UTF7.GetBytes(OrderCode);
string EncString = Convert.ToBase64String(Enc);
#endregion
#region Decode
byte[] Dec = Convert.FromBase64String(EncString);
string b = ASCIIEncoding.UTF7.GetString(Dec);
#endregion
Tou can al use UTF8,UTF32
