public async task<actionresult> create([bind(include = "postid,address,posttitle,postcontent,postimage,taglist")] postviewmodel postviewmodel,httppostedfilebase file) { if (modelstate.isvalid) { string filename = "1.jpg"; if (file != null && file.contentlength > 0) { filename = path.getfilename(file.filename); var path = path.combine(server.mappath("~/content/images/blog"), filename); file.saveas(path); } else { return view(postviewmodel); } var selectedtags = reconsiletags(postviewmodel.taglist); post post = new post { posttitle = postviewmodel.posttitle, postcontent = postviewmodel.postcontent, address = postviewmodel.address, tags = selectedtags }; post.postimage = filename ; post.authorid = user.identity.getuserid(); db.posts.add(post); await db.savechangesasync(); return redirecttoaction("index"); } the file (httppostedfilebase) null !? please me solve this. (i'm newbie in asp mvc )
instead of passing httppostedfilebase parameter, remove , following:
httpfilecollectionbase filecollection = request.files; if(filecollection.count > 0) { foreach(var file in filecollection) { // httppostedfilebase object } }
