c# - TempData is empty after RedirectToAction in catch block. What could be the reason? -

-

I've been using TempData for a long time and I'm facing a weird problem for me. The scenario is: Make 

  [http post] Make public analytical (ProductContodelNewsprint) {// and try to upload the product to DB / External site. Try {UploadProductToEbay (newProduct); } Hold {TempData ["error"] = "error"; Return Redirect Action ("Edit", newProduct.Id); } ...} [HTPGet] edit public action result (id) {var error = tempdata ["error"]; // Temporary data collection is empty at this point and it has no idea why ...}   
 The upload fails and  returns the redirection tie ("Edit" , New product ID); The execution of the line is "TempData [" error "] ="  
  UPDATE:  when I use 
 , error " ; RedirectToAction (...);   
 Block out  Hold  Everything is fine, the temporary data value is moved to the  edit  operation.   
 
 
 It seems that the problem is  return redirect action ("edit", newProduct.Id);  is in the statement. 
 Try this statement instead of  Return Redirect Action ("Edit", New {ID = NewProject.Id}); Type the  object  of the root parameter and you  integer .

I am trying to implement a screen-scraps application that opens a URL in which a parameter changes as it is for a loop: var data = [ '100', '101', '102', '103', '104']; (Var indexA = 0; indexA & lt; data.length; indexA ++) for {Phantom Generation ({'port': freeport}, function (pH) {ph.create page (function (page) {page.open ("http: //...++ data [index B] +" ...
