c# - Get query string values when submitting a form...MVC3 -

In my MVC 3 app, if I type a query string value in the URL and the entry is killed, I can get I typed:

  localhost: 34556? DB = test   
 My default action will be fire:  
  public action index (string db)   
 variable There is a "test" in DB.  
 Now, I need to submit the form and read the query string value, but when I submit the form via jQuery.  
  (function (e $ ('# btnLogOn')) {e.preventDefault (); document.forms [0] .submit ();});   
 and the following I am sending:  
  @using (HTML.BeginForm ("Login", "Home", New {id = "Form1" "}, FormMethod.Post))   
 Action here:  
  [HttpPost] public ActionResult login (logOnModel logOnModel, string database) {string dbName = Request .QueryString ["db"]; }   
 variable dbName is zero because the request.QueryString ["db"] is zero, therefore variable db is being passed and I do not know why after submitting a form what is Can query string get variable? Thank you   
 
 
 You can do something like  
 Controllers:  < Pre>  [HTTPGet] Public Action Result Login (string dbnm) {logonview model love = new logonview model (); // Returning Voododl Here Return here (Love); } [HTTPOst] Public Action Result Login (LogoneView Model Limum, String DBNM) {if (ModelState.IsValid) {// You can refer to DBN name by typing DBN name (i.e.) string test = dbn name here Are; // Which one you want here is probably a redirect? } See Return (Love); }   
 view module:  
  public class logonview model {// whatever assets you have}}
