CryptoStream - Read vs Write - Is there any difference?

Question

Is there any change in the code needed between if we use CryptoStream with CryptoStreamMode.Read or with CryptoStreamMode.Write ?

(Besides reading from it and writing to an outStream or reading from an inStream and writing to the CryptoStream, of course.)

If you absolutely need to see code, here's some (See end of 3rd line):

using (Aes aes = Aes.Create())
using (ICryptoTransform encryptorTransform = aes.CreateEncryptor())
using (CryptoStream outAesStream = new CryptoStream(outStream, encryptorTransform, CryptoStreamMode.Write))
{
   //...
}
