asp.net mvc 4 letter from site add attachment -

i have feedback form on site, looks

i created model form

 using system;  using system.collections.generic;  using system.componentmodel.dataannotations;  using system.linq;  using system.web;   namespace corepartners_site2.models  {      public class feedbackform      {     public string name { get; set; }      public string email { get; set; }     public string phone { get; set; }     public string company { get; set; }     public string additionalinformation { get; set; }      [fileextensions(extensions = "doc,txt,pdf")]     public httppostedfilebase projectinformation { get; set; }      }  } 

and created view

@using (html.beginform("feedback", "home", formmethod.post, new { id = "feedback-form" })) {     @html.textboxfor(model => model.name, null, new { @class = "text-field" })                        @html.textboxfor(model => model.email, null, new { @class = "text-field" })                        @html.textboxfor(model => model.phone, null, new { @class = "text-field" })     @html.textboxfor(model => model.company, null, new { @class = "text-field" })     @html.textareafor(model => model.additionalinformation, new { cols="1", rows="1" })                   @html.textboxfor(model => model.projectinformation, null, new { type="file", @class="input-file" })     <a href="#" class="link1" onclick="document.getelementbyid('feedback-form').submit()"><em><b>send</b></em></a> } 

i'd know form work a submit instead <input type="submit" /> ?

and dont know how make attachment letter, tried make

   [httpget]     public actionresult feedback()     {         return view();     }      [httppost]     public actionresult feedback(feedbackform model)     {          system.net.mail.mailmessage msg = new system.net.mail.mailmessage();         msg.bodyencoding = encoding.utf8;          msg.from = new mailaddress(model.email, @resources.global.feedback_email_title);         msg.to.add("tayna-anita@mail.ru");          string message = @resources.global.feedback_name + ": " + model.name + "\n"                         + @resources.global.feedback_email + ": " + model.email + "\n"                         + @resources.global.feedback_phone + ": " + model.phone + "\n"                         + @resources.global.feedback_company + ": " + model.company + "\n\n"                         + model.additionalinformation;         msg.body = message;         msg.isbodyhtml = false;          //attachment         if (model.projectinformation != null)         {             httppostedfilebase attfile = model.projectinformation;             int attachfilelength = attfile.contentlength;             if (attachfilelength > 0)             {                 string strfilename = path.getfilename(model.projectinformation.filename);                 model.projectinformation.saveas(server.mappath(strfilename));                 mailattachment attach = new mailattachment(server.mappath(strfilename));                 msg.attachments.add(attach);                 string attach1 = strfilename;             }         }          smtpclient client = new smtpclient("smtp.mail.ru", 25);         client.usedefaultcredentials = false;         client.enablessl = false;          try         {             client.send(msg);         }          catch (exception ex)         {         }          feedbackform tempform = new feedbackform();         return view(tempform);     } 

but shows mistake in msg.attachments.add(attach); , seems not work.

well answer first question yes can use anchor tag in place of submit input.

you want disable tags default behaviour javascript/jquery , have submit form:

$(function () {     $('a.something').on("click", function (e) {         e.preventdefault();         $('feedback-form').submit();     }); }); 

the error receiving because using wrong object type msg.attachments.add() method. need use attachment object not mailattachment object.

something this:

stream attachmentstream = file.openread (file); streams.add (attachmentstream); mail.attachments.add (new attachment (attachmentstream, path.getfilename (file));
