Is it possible to list the names of all controllers and their actions programmatically?
I want to implement database driven security for each controller and action. As a developer, I know all controllers and actions and can add them to a database table, but is there any way to add them automatically?
string currentViewName = ((WebFormView)ViewContext. View). ViewPath; You can retrive both physical name of current view and action that triggered it.
You can have two method with the same name (and in fact it's a good practice to do that for forms). There are two requirements to have similar named methods. The methods must have different parameters. This is dictated by the programming language and is basically method overloading.
Figure 2: Types of Action Result There are two methods in Action Result. One is ActionResult() and another one is ExecuteResult().
A controller action returns something called an action result. An action result is what a controller action returns in response to a browser request. The ASP.NET MVC framework supports several types of action results including: ViewResult - Represents HTML and markup.
The following will extract controllers, actions, attributes and return types:
Assembly asm = Assembly.GetAssembly(typeof(MyWebDll.MvcApplication));
var controlleractionlist = asm.GetTypes()
.Where(type=> typeof(System.Web.Mvc.Controller).IsAssignableFrom(type))
.SelectMany(type => type.GetMethods(BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.Public))
.Where(m => !m.GetCustomAttributes(typeof( System.Runtime.CompilerServices.CompilerGeneratedAttribute), true).Any())
.Select(x => new {Controller = x.DeclaringType.Name, Action = x.Name, ReturnType = x.ReturnType.Name, Attributes = String.Join(",", x.GetCustomAttributes().Select(a => a.GetType().Name.Replace("Attribute",""))) })
.OrderBy(x=>x.Controller).ThenBy(x => x.Action).ToList();
If you run this code in linqpad for instance and call
controlleractionlist.Dump();
you get the following output:
You can use reflection to find all Controllers in the current assembly, and then find their public methods that are not decorated with the NonAction
attribute.
Assembly asm = Assembly.GetExecutingAssembly();
asm.GetTypes()
.Where(type=> typeof(Controller).IsAssignableFrom(type)) //filter controllers
.SelectMany(type => type.GetMethods())
.Where(method => method.IsPublic && ! method.IsDefined(typeof(NonActionAttribute)));
I was looking for a way to get Area, Controller and Action and for this I manage to change a little the methods you post here, so if anyone is looking for a way to get the AREA here is my ugly method (which I save to an xml):
public static void GetMenuXml()
{
var projectName = Assembly.GetExecutingAssembly().FullName.Split(',')[0];
Assembly asm = Assembly.GetAssembly(typeof(MvcApplication));
var model = asm.GetTypes().
SelectMany(t => t.GetMethods(BindingFlags.Instance | BindingFlags.DeclaredOnly | BindingFlags.Public))
.Where(d => d.ReturnType.Name == "ActionResult").Select(n => new MyMenuModel()
{
Controller = n.DeclaringType?.Name.Replace("Controller", ""),
Action = n.Name,
ReturnType = n.ReturnType.Name,
Attributes = string.Join(",", n.GetCustomAttributes().Select(a => a.GetType().Name.Replace("Attribute", ""))),
Area = n.DeclaringType.Namespace.ToString().Replace(projectName + ".", "").Replace("Areas.", "").Replace(".Controllers", "").Replace("Controllers", "")
});
SaveData(model.ToList());
}
Edit:
//assuming that the namespace is ProjectName.Areas.Admin.Controllers
Area=n.DeclaringType.Namespace.Split('.').Reverse().Skip(1).First()
