    <h2>Contrary to the answers here, you DON'T need to worry about encoding <strong><em>if</em></strong> the bytes don't need to be interpreted!</h2> <p>Like you mentioned, your goal is, simply, to <em>"get what bytes the string has been stored in"</em>.<br> (And, of course, to be able to re-construct the string from the bytes.)</p> <h3>For those goals, I honestly do <em>not</em> understand why people keep telling you that you need the encodings. You certainly do NOT need to worry about encodings for this.</h3> <p>Just do this instead:</p> <pre><code>static byte[] GetBytes(string str) { byte[] bytes = new byte[str.Length * sizeof(char)]; System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length); return bytes; } static string GetString(byte[] bytes) { char[] chars = new char[bytes.Length / sizeof(char)]; System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length); return new string(chars); } </code></pre> <p>As long as your program (or other programs) don't try to <em>interpret</em> the bytes somehow, which you obviously didn't mention you intend to do, then there is <strong>nothing</strong> wrong with this approach! Worrying about encodings just makes your life more complicated for no real reason.</p> <h2>Additional benefit to this approach:</h2> <h3>It doesn't matter if the string contains invalid characters, because you can still get the data and reconstruct the original string anyway!</h3> <p>It will be encoded and decoded just the same, because you are <em>just looking at the bytes</em>.</p> <p>If you used a specific encoding, though, it would've given you trouble with encoding/decoding invalid characters.</p>

    1. CO+1 Exactly my thoughts, I don't know the insistence of some peeps here about encoding. Just need to do a memory dump / serialization(the default serialization library from Microsoft has flaws though). I hope I know this BlockCopy API before :-)

    2. CO@MichaelBuen: Yup. As long as your memory dumps/serializations do *not* try to interpret the data, it's all fine. The rule of thumb to remember is this: If your program (or a different program) needs to convert the output of `GetBytes` back to the same string, it may *only* use `GetString` to do this. As long as you don't violate that, you can ignore the concept of encodings entirely.

    3. CO@Mehrdad I agree with your logic, but I was surprised when I tested it that the encoding method is slightly faster. I guess I was expecting your method to be faster (there isn't much in it though)

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
