[Tips]: ASP.NET MVCはコントロールの名前を得た

If you have the ControllerContext class instance available then you can use this code:

string controllerName= controllerContext.RouteData.GetRequiredString("controller");
  
the HTML helper provides access to the ControllerContext, you can use it in view page: 
Html.ViewContext.Controller.ControllerContext.RouteData.GetRequiredString("controller")
