I've never tried encrypting something exactly as you are trying, but I believe the problem is that you're not calling the write method of the crypto stream. Check out the information on the write method of the crypto stream for for information. Below is a function I use to encrypt a string. As you can see I call the write method of the crypto stream and pass in a byte array of the data I want to encrypt. Hopefully the code below helps you.
Public Shared Function Encrypt(value As String, key() As Byte, iv() As Byte) As string
    Dim bytValue() As Byte      'The data to be encrypted
    Dim bytEncoded() As Byte    'The data after encryption
    Dim rijndael As New Rijndael Managed
    Dim ms As New MemoryStream  'The stream to write the encrypted data to
    
    bytValue = Encoding.ASCII.GetBytes(value.ToCharArray)   'Convert plain text to byte array
    'Create the crypto stream with the stream to write the encrypted data to (ms = Memory Stream)
    Using CryptoStream As New CryptoStream(ms, rijnadel.CreateEncryptor(key, iv), CryptoStreamMode.Write)
        'Encrypt the plaint text byte array (bytValue) to the memory stream (ms)
        CryptoStream.Write(bytValue, 0, bytValue.Length)
        'Flush crypto stream
        CryptoStream.FlushFinalBlock()
        'Get the encrypted byte array from the memory stream (ms)
        bytEncoded = ms.ToArray
        'Close memory stream
        ms.Close()
    End Using
    
    'Convert the encrypted byte array (bytEncoded) to a Base64 string and return it
    Return Convert.ToBase64String(bytEncoded)
End Function
