I have an problem using the RedirectToAction method in mvc. My Map route look like this.

routes.MapRoute(
         "Project",  // Route name
         "{Controller}/{Action}/{projectId}/{machineName}/{companyId}",
          new { controller = "Project", action = "Directives", projectId = 0, machineName = "", companyId = 0 }  // Parameter defaults);

And the sending Controller look like this:

[HttpPost]
[ValidateInput(false)]
public ActionResult Create(Project project, string text)
{
    ViewBag.MachineType = new List<string>(new string[] { "Machine Type A", "Machine Type B", "Machine Type C", "Machine Type D", "Machine Type E" });

    if (ModelState.IsValid)
    {
        UserAccess user = (UserAccess)(Session["UserAccessInfo"]);

        Int64 projectId = DataBase.DBProject.InsertProject(project.ProjectNumber, project.MachineName, project.MachineNameEnglish, 1, project.Serial, text, user.Company_Id,project.MachineType);

        return RedirectToAction ("Directives", "Project", new { projectId = 48, machineName = "Netduino", companyId = 27 });
       // return RedirectToAction("Directives", "Project", new { projectId = projectId, machineName = project.MachineName, CompanyId = user.Company_Id });
    }
    else
    {
        ModelState.AddModelError("", "Invalid username or password");
    }

    return View();

}</pre>

And the recivering controller:

public ActionResult Directives(int projectId, string machineName, int companyId)
		{
			convertedDirectives = 
new List<Models.Directives>();
			ViewBag.MachineName = machineName;
			ViewBag.ProjectId = projectId;
			List<object> Directives = new List<object>();
		   
			if (ModelState.IsValid)
			{
				Directives = DataBase.DBProject.GetDirectives(companyId);
				foreach (List<object> dir in Directives)
				{
					Directives newDirective = new Models.Directives();
					newDirective.CompanyID = Convert.ToInt32(dir[0]);
					newDirective.DirectiveId = Convert.ToInt32(dir[1]);
					newDirective.Id = Convert.ToInt32(dir[2]);
					newDirective.DirectiveName = Convert.ToString(dir[3]);
					newDirective.DirectiveNameShort = Convert.ToString(dir[4]);
					newDirective.Created = Convert.ToDateTime(dir[5]);

					convertedDirectives.Add(newDirective);
				}
			}
			else
			{
				ModelState.AddModelError("", "An error has ");
			}

			ViewBag.DirectivesList = convertedDirectives;
			return View();
		}

In the Adress bar it looks like this:

http://localhost:1843/Project/Directives?projectId=48&machineName=NetDuino&companyId=27

But the way i want it is like this.

http://localhost:1843/Project/Directives/48/Netduino/27

But if trie to type the url in manuel it works prefect. What is im doing wrong?

Try RedirectToRoute. That should work for your case. A quick example is given below:

routes.MapRoute("Project",  // Route name
                "Route/Directives/{projectId}/{machineName}/{companyId}",
                new { controller = "Route", action = "Directives", projectId = @"\d+", machineName = @"\S+", companyId = @"\d+" });

Notice that I have hard-coded the controller & action, you could also use your method and pass the controller and action as route values.

Now in your controller, instead of RedirectToAction, use RedirectToRoute as shown in the Index action method.

C#

public class RouteController : Controller
{
    //
    // GET: /Route/

    public ActionResult Index()
    {
        return RedirectToRoute("Project", new { projectId = 4, machineName = "somemachine", companyId = 7 });
    }

    public ActionResult Directives(int projectId, string machineName, int companyId)
    {
        ViewData["Data"] = string.Format("{0},{1},{2}", projectId, machineName, companyId);
        return View();
    }
}

Now, if you navigate to /route/index it will redirect you to /Route/Directives/4/somemachine/7 instead of how you get currently.

Hope this helps!
