FileNinja

Wrote this for personal use, wanted to encrypt some photos/text documents.
Won't work with very large files right now.

This is actually pretty good and could be useful at certain points, in my opinion that is.
Good job.

AES.Mode = CipherMode.ECB;

OP you just dun goofed cryptographically speaking.

Electronic Code Book is a broken Stream Cipher
Blocks of identical text are encrypted identically. (Yes, this is bad extremely bad)
With ECB, the text "chocolate" would always gets encrypted to "sjkskhbqp". So if your plaintext was "I eat chocolate I like chocolate" it would get encrypted to "O pbq sjkafhbqp O hoxp sjkafhbqp"
see the problem?

To be blunt, since you are using ECB, OP, your encryption program is completely broken.

Use CTR mode or CBC mode instead of ECB

Thanks for that piece of info.
But I just quickly tested it again and that doesn't seem to be the case. Try it out yourself and let me know?

It isn't a problem with code in .NET or C#

it is a problem with security

I understand what you're saying. But if that's the case, shouldn't encrypting two simple plain text files containing a few identical words with the same key result in their corresponding ciphertexts looking similar? Is that not what makes it semantically insecure?
