Various MVC4 actions based on GET variable

Question

Is there a way to force MVC4 to call different actions based on the GET variable in the URL?

For example, suppose I have the following two actions.

[HttpPost] public ActionResult SubmitCrash(CrashReport rawData) { return View(); } [HttpPost] public ActionResult SubmitBug(BugReport data) { return View(); } 

Can the following URLs be used so that MVC4 "chooses" which action to invoke?

 http://MySite/Submit?Crash (calls 'SubmitCrash') http://MySite/Submit?Bug (calls 'SubmitBug') 

UPDATE:
I know very well that I can use actions / URLs as they are and do something with routing to make this happen (this is what I'm doing now), but I'm really interested in the GET vars question.

This is not as neat as it could be, but you can use the "root" action for this:

 public ActionResult Submit(string method) { return Redirect("Submit"+method); } public ActionResult SubmitCrash() { return View(); } public ActionResult SubmitBug() { return View(); } 

Edit
I am extending ActionNameAttribute to meet your needs, so you can write this:

 //handles http://MySite/Submit?method=Crash [ActionNameWithParameter(Name = "Submit", ParameterName = "method", ParameterValue = "Crash")] public ActionResult SubmitCrash() { return View(); } //handles http://MySite/Submit?method=Bug [ActionNameWithParameter(Name = "Submit", ParameterName = "method", ParameterValue = "Bug")] public ActionResult SubmitBug() { return View(); } [AttributeUsage(AttributeTargets.Method, AllowMultiple = false, Inherited = true)] public sealed class ActionNameWithParameterAttribute : ActionNameSelectorAttribute { public string Name { get; private set; } public string ParameterName { get; private set; } public string ParameterValue { get; private set; } public ActionNameAttribute(string name, string parameterName, string parameterValue) { if (string.IsNullOrEmpty(name)) { throw new ArgumentException(MvcResources.Common_NullOrEmpty, "name"); } this.Name = name; this.ParameterName = parameterName; this.ParameterValue = parameterValue; } public override bool IsValidName(ControllerContext controllerContext, string actionName, MethodInfo methodInfo) { return string.Equals(actionName, this.Name, StringComparison.OrdinalIgnoreCase) && string.Equals(controllerContext.HttpContext.Request.QueryString.Get(ParameterName) , this.ParameterValue , StringComparison.OrdinalIgnoreCase); } } 

Answer 2

Why not create routes for this?

 routes.MapRoute( name: "SubmitCrash", url: "Submit/Crash", defaults: new { Action = "SubmitCrash", Controller = "NameOfController", }); routes.MapRoute( name: "SubmitBug", url: "Submit/Bug", defaults: new { Action = "SubmitBug", Controller = "NameOfController", });
