Hi Xola Dlamini, I had gone through attached code "problem.docx" and come to know that you want to redirect to "Controller B" action method "ValidateFile" from "Controller A" in action method "Upload" and again get back to "Upload" in "Controller A" . i.e. Controller A => Controller B => Controller A Ideally, this can not be possible because once MVC redirects to another controller i.e. "Controller B" than it can not come back to calling controller i.e. "Controller A". Now, you can achieve your need in 2 ways: Put the "ValidateFile" in same controller i.e. in "Controller A" Create class file instead of controller and put the "ValidateFile" in it and use like above. But, in that case; how the arguments "HttpPostedFileBase file" will be accessed that you have you see. Hope, this will help you!

You could also simply redirect straight to the method like so: public class ThisController { public ActionResult Index() { return RedirectToAction("OtherMethod", "OtherController"); } }
