C# , javascript and FileUpload Asp.net

I have a FileUpload Control on a webpage.  

On a button I have a OnClientClick that execute
a JavaScript that let the user enter e-mail adresses to send some mail to.
than it calls an WebMethod that sends the e-mail and then update the
database with some information.

I need to do the actual fileupload (to the database)  inside the webmethod
so I wounder how I can get access to the fileupload
from my webmethod?




 


My webmethod today:

[WebMethod(EnableSession = true)]
public static string SendMail(string id, string emails, string comments)
    {
        User u;
        u = (User)HttpContext.Current.Session["UserInfo"];
        if (emails.EndsWith(";"))
            emails = emails.Substring(0, emails.Length - 1);
       

        int res = MailManager.Send(int.Parse(id), u, comments, emails);
        return res.ToString();
    }

Using a generic handler :
public class Handler : IHttpHandler {
    
    public void ProcessRequest (HttpContext context) {
        User u;
        u = (User)HttpContext.Current.Session["UserInfo"];

        string id = context.Request.QueryString.Get("id");
        string emails = context.Request.QueryString.Get("emails");
        string comments = context.Request.QueryString.Get("comments");

        if (emails.EndsWith(";"))
        {
            emails = emails.Substring(0, emails.Length - 1);
        }

//http://msdn.microsoft.com/en-us/library/system.web.httppostedfile.saveas(v=vs.110).aspx
        HttpPostedFile attachment = context.Request.Files[0];
        //string filename = "C:\\Temp\\" + attachment.FileName;
        //attachment.SaveAs(filename);

        int res = MailManager.Send(int.Parse(id), u, comments, emails, attachment);

        context.Response.ContentType = "text/plain";
        context.Response.Write(res.ToString());
    }
 
    public bool IsReusable {
        get {
            return false;
        }
    } 

}
