How to insert an attachment to a System.Net.Mail.mailMessage by using Body properties
<p>I need to send email with attachment. No problem if I do it by myself, but...</p>

<p>Inside the company I work for, I need to pass through a web service awaiting an email and a body.</p>

<p>I know that the implementation of this service use System.Web.mail.Mailmessage doing probably something like this:</p>

<pre><code>MailMessage mm = new MailMessage();
mm.to = email_;
mm.body = body_;
...
</code></pre>

<p>So, is there a way to create a string that'll contain my attachement so I can send it to the web service ?</p>

<p>thx.</p>

<p>--Edition--
I must use a class "TheCompanyMail" that has 2 properties (to,body) and one method (send). This class is a proxy to a webservice. This webservice is the one that really sends the mail. 
The problem is that I need to add an attachement to the mail and really don't know how to do it.</p>

<p>Example</p>

<pre><code>File f = MyFuturAttachementFile;

TheComapyMail m = new TheCompanyMail();
m.to = "myCustomer@Company.com"
m.body = "Here is the file you're waiting for:"+f.ToString(); //this of course doesn't work !!!
m.send();
</code></pre>

<p>So I'm wondering if I can format the string of the body property to add attachement ?</p>
