Answer 1

Both StreamReader and BinaryReader can be used to get data from binary file

Well, StreamReader can be used to get text data from a binary representation of text.

BinaryReader can be used to get arbitrary binary data. If some of that binary data happens to be a representation of text, that's fine - but it doesn't have to be.

Bottom line:

• If the entirety of your data is a straightforward binary encoding of text data, use StreamReader.
• If you've fundamentally got binary data which may happen to have some portions in text, use BinaryReader

So for example, you wouldn't try to read a JPEG file with StreamReader.
