c# - Request .Form returns null -

-

i not able retrieve values in controller, returning null. please me find out have done wrong.

below code

index.aspx

<form id="form1" method="post" action="/sample/index" enctype="multipart/form-data"> <div>     <input  type="text" id="pcid" value=<%=model.pcid %> /></div>     <input type="file" value="browse" id="file"/>     <input type="submit" id="submit" value="save"/></div> </form>

and in controller

[httppost] public actionresult index(httppostedfilebase file) {     string pcid = request.form["pcid"];     list<string> fileconfigdata = new list<string>();      if (file != null && file.contentlength > 0)     {         string folderpath = mpath.getfolderpath();         var filename = path.getfilename(file.filename);         string filepath = server.mappath(folderpath + pcid) + "\\" + filename;         file.saveas(filepath);     }     return view(); }

try adding name input field :

<input  type="text" id="pcid" name="pcid" value=<%=model.pcid %>

according w3c specification, every form input element should have name attribute specified. otherwise element not processed.
