How to add an email attachment from a byte array?

Question

I have a `byte[]` with the contents of file. I would like to send it as an attachment using `System.Net.Mail`. I noticed the attachment class has 1 overload which accepts a stream. ``` Attachment att = new Attachment(Stream contentStream,string name); ``` Is it possible to pass the `byte[]` through this overload?

Accepted Answer

Simplest way:

```
Attachment att = new Attachment(new MemoryStream(bytes), name);
```

Note that unless you do funky stuff with asynchronous operations, `MemoryStream` is safe to leave undisposed, which may make life easier for you. Admittedly there's no guarantee that that will be true in the future, but I think it's unlikely that it will change. I can't see any indication as to whether disposing of the attachment disposes of its stream :(
