　　在ASP.NET MVC开发中，通常有很多Controller，Action．我们可以从外面以反射,Linq的语法来获取些信息．Linq语法使得代码可读性高．

看UnitTest:

/// <summary>     /// Tests the get info from controller.     /// </summary>     /// <remarks>javascript:void(0) </remarks>     [TestMethod]     public void TestGetInfoFromController()     {         var controllers = from t in GetAllControllerTypes() where typeof(Controller).IsAssignableFrom(t) && !t.IsAbstract orderby t.FullName from m in t.GetMethods(BindingFlags.Instance | BindingFlags.Public | BindingFlags.DeclaredOnly) where !m.IsSpecialName select new { ControllerName = FormatControllerName(t.FullName), ActionName = m.Name, Params = m.GetParameters() };           controllers.ToList().ForEach(c => Debug.WriteLine(string.Format("Controller: {0}, Action: {1}({2})",                                                                         c.ControllerName, c.ActionName,                                                                         string.Join(", ",                                                                                     c.Params.Select(p => p.Name).                                                                                         ToArray()))));         Debug.WriteLine(string.Format("Controller/action count: {0}", controllers.Count()));         Debug.WriteLine(string.Format("Controller count: {0}", controllers.GroupBy(c => c.ControllerName).Count()));            }      /// <summary>     /// Gets all controller types.     /// </summary>     /// <returns>all types in an assembly where my controllers can be found</returns>     private static Type[] GetAllControllerTypes()     {         return typeof(ProductManageController).Assembly.GetTypes();     }      /// <summary>     /// Formats the name of the controller,remove all of the namespace information from the controller names     /// </summary>     /// <param name="typeName">Name of the type.</param>     /// <returns></returns>     private static string FormatControllerName(string typeName)     {         return typeName.Replace("Demo1Web.", string.Empty).Replace("Controllers.", string.Empty);     }

上面代码将输出：

Controller: HomeController, Action: Index()

Controller: HomeController, Action: test()

Controller: HomeController, Action: ThisActionHasProblem()

Controller: HomeController, Action: Category(form)

Controller: ProductManageController, Action: Delete(ProductId)

Controller: ProductManageController, Action: DeleteSome(form)

Controller: ProductManageController, Action: EditProduct(Id)

Controller: ProductManageController, Action: ProductList(id)

Controller: ProductManageController, Action: QueryAllProducts(id, form)

Controller: ProductManageController, Action: SaveByBinder(productId, product)

Controller: ProductManageController, Action: Save(ProductId, form)
