now it says padding cannot be removed...here is my entire code

Member 10549697 24-Mar-16 13:13pm

byte[] cipherbytes = Encoding.ASCII.GetBytes(label6.Text);
System.IO.MemoryStream ms = new System.IO.MemoryStream(cipherbytes);
CryptoStream cs = new CryptoStream(ms, desObj.CreateDecryptor(), CryptoStreamMode.Read);
cs.Read(cipherbytes, 0, cipherbytes.Length);
plainbytes2 = ms.ToArray();
cs.Close();
ms.Close();
string garbage = Encoding.ASCII.GetString(plainbytes2);
label2.Text = garbage.Substring(0, plainbytes.Length);
}

There isn't enough code there to know what you're doing, it looks like you're pretty much copying this code so have a read of the thread
