C# - How to redirect URL with query string parameter in MVC4

In ASP.NET MVC 4, you can redirect a URL with query string parameters using the RedirectToAction method. Here's how you can achieve it:

using System.Web.Mvc; public class YourController : Controller { public ActionResult YourAction(string parameter1, string parameter2) { // Your logic here... // Redirect to another action with query string parameters // Example: redirect to "NewAction" action in the same controller with query string parameters return RedirectToAction("NewAction", new { parameter1 = parameter1, parameter2 = parameter2 }); } public ActionResult NewAction(string parameter1, string parameter2) { // Your logic for the new action... return View(); } }

In this example:

  • YourAction is the action method where you want to perform the redirection.
  • NewAction is the action method to which you want to redirect.
  • RedirectToAction method is used to redirect to the NewAction action with the specified query string parameters.

Make sure to replace "YourController" with the name of your actual controller and "YourAction" and "NewAction" with the names of your actual action methods.

This method allows you to maintain or pass query string parameters during the redirection process.
