Code

<formclass="cmxform form-horizontal tasi-form"Id="SubmitForm"Method="POST"action="ADD"Novalidate="novalidate"Enctype="Multipart/form-data">                        @{                            if(!ViewData.ModelState.IsValid) {<divclass="Alert Alert-danger alert-dismissable"> <button type="Button" class="Close"data-dismiss="Alert"aria-hidden="true">x</button>@string.

Note: The form to add Enctype= "Multipart/form-data", indicating that there are files to submit.

To add httppostedfilebase file, file corresponds to the Name property of the upload control in HTML.

Background:

[HttpPost] Publicactionresult Add (Service.Dto.BannerInfoDto Dto, httppostedfilebase file) {stringFileName =""; if(File = =NULL) {Modelstate.addmodelerror ("Error","Please select a picture. Jpg/.png/.gif"); returnView (DTO); }            if(File! =NULL)            {                stringFileext =path.getextension (file. FileName).                ToLower (); if(!". Jpg/.png/.gif". Contains (Fileext)) {Modelstate.addmodelerror ("Error","The picture is not formatted correctly. Jpg/.png/.gif"); returnView (DTO); } fileName="~/uploadfile/bannerinfo/"+ DateTime.Now.ToString ("YYYYMMDDHHMMSS") +Fileext; stringSerpath =Server.MapPath (fileName); Try{file.                SaveAs (Serpath); }                Catch(Exception ex) {Modelstate.addmodelerror ("Error","Upload exception:"+Ex.                    Message); returnView (DTO); }} Domain.rl_bannerinfo Model= new Domain.rl_bannerinfo (); Model. Linkurl=DTOs.            Linkurl; Model. Name=DTOs.            Name; Model. IMG=FileName; BOOLresult =Bannerinfomanage.save (model); if(Result) {returnRedirecttoaction ("Manage"); }            Else{modelstate.addmodelerror ("Error","Save failed"); returnView (DTO); }        }

That's probably it.
