asp.net mvc - Issue when submitting a param into controller -

this cannot figure out while:

in view wrote this:

@using(html.beginform("pindex","home")){     <select name ="particalview">         <option value="1">option 1</option>         <option value="2">option 2</option>     </select> 

the controller behind is:

[httppost]         public actionresult pindex(string i) {             if (i == "1")                 viewbag.page = 1;             else if(i == "2")                 viewbag.page = 2;              if(i == null)                 viewbag.page = 3;              return view();         } 

whatever select, controller fails param of select list, can tell me missed?

change parameter in pindex particalview

[httppost]         public actionresult pindex(string particalview) {             if (particalview == "1")                 viewbag.page = 1;             else if(particalview == "2")                 viewbag.page = 2;              if(particalview == null)                 viewbag.page = 3;              return view();         }
