这将为您提供一个字典，其中控制器类型作为键，其 MethodInfos 的 IEnumerable 作为值。

        var assemblies = AppDomain.CurrentDomain.GetAssemblies(); // currently loaded assemblies
        var controllerTypes = assemblies
            .SelectMany(a => a.GetTypes())
            .Where(t => t != null
                && t.IsPublic // public controllers only
                && t.Name.EndsWith("Controller", StringComparison.OrdinalIgnoreCase) // enfore naming convention
                && !t.IsAbstract // no abstract controllers
                && typeof(IController).IsAssignableFrom(t)); // should implement IController (happens automatically when you extend Controller)
        var controllerMethods = controllerTypes.ToDictionary(
            controllerType => controllerType,
            controllerType => controllerType.GetMethods(BindingFlags.Public | BindingFlags.Instance).Where(m => typeof(ActionResult).IsAssignableFrom(m.ReturnType)));

它不仅仅查找当前程序集，还会返回方法，例如返回 JsonResult 而不是 ActionResult。（JsonResult 实际上继承自 ActionResult）

编辑：对于 Web API 支持

更改

&& typeof(IController).IsAssignableFrom(t)); // should implement IController (happens automatically when you extend Controller)

为

&& typeof(IHttpController).IsAssignableFrom(t)); // should implement IHttpController (happens automatically when you extend ApiController)

并删除此：

.Where(m => typeof(ActionResult).IsAssignableFrom(m.ReturnType))

因为 Web API 方法几乎可以返回任何内容。（POCO，HttpResponseMessage，...）

This will give you a dictionary with the controller type as key and an IEnumerable of its MethodInfos as value.

        var assemblies = AppDomain.CurrentDomain.GetAssemblies(); // currently loaded assemblies
        var controllerTypes = assemblies
            .SelectMany(a => a.GetTypes())
            .Where(t => t != null
                && t.IsPublic // public controllers only
                && t.Name.EndsWith("Controller", StringComparison.OrdinalIgnoreCase) // enfore naming convention
                && !t.IsAbstract // no abstract controllers
                && typeof(IController).IsAssignableFrom(t)); // should implement IController (happens automatically when you extend Controller)
        var controllerMethods = controllerTypes.ToDictionary(
            controllerType => controllerType,
            controllerType => controllerType.GetMethods(BindingFlags.Public | BindingFlags.Instance).Where(m => typeof(ActionResult).IsAssignableFrom(m.ReturnType)));

It looks in more than just the current assembly and it will also return methods that, for example, return JsonResult instead of ActionResult. (JsonResult actually inherits from ActionResult)

Edit: For Web API support

Change

&& typeof(IController).IsAssignableFrom(t)); // should implement IController (happens automatically when you extend Controller)

&& typeof(IHttpController).IsAssignableFrom(t)); // should implement IHttpController (happens automatically when you extend ApiController)

and remove this:

.Where(m => typeof(ActionResult).IsAssignableFrom(m.ReturnType))

Because Web API methods can return just about anything. (POCO's, HttpResponseMessage, ...)

您可以使用它在运行时反映程序集，以在返回 ActionResult 的控制器中生成方法列表：

    public IEnumerable<MethodInfo> GetMvcActionMethods()
    {
        return
            Directory.GetFiles(Assembly.GetExecutingAssembly().Location)
                .Select(Assembly.LoadFile)
                .SelectMany(
                    assembly =>
                    assembly.GetTypes()
                            .Where(t => typeof (Controller).IsAssignableFrom(t))
                            .SelectMany(type => (from action in type.GetMethods(BindingFlags.Public | BindingFlags.Instance) 
                                                 where action.ReturnType == typeof(ActionResult) 
                                                 select action)
                                        )
                    );
    }

这将为您提供操作，但不会提供视图列表（即，如果您可以在每个动作）

You can use this to reflect over the assemblies at runtime to produce a list of methods in Controllers that return ActionResult:

    public IEnumerable<MethodInfo> GetMvcActionMethods()
    {
        return
            Directory.GetFiles(Assembly.GetExecutingAssembly().Location)
                .Select(Assembly.LoadFile)
                .SelectMany(
                    assembly =>
                    assembly.GetTypes()
                            .Where(t => typeof (Controller).IsAssignableFrom(t))
                            .SelectMany(type => (from action in type.GetMethods(BindingFlags.Public | BindingFlags.Instance) 
                                                 where action.ReturnType == typeof(ActionResult) 
                                                 select action)
                                        )
                    );
    }

This will give you the actions, but not the list of Views (i.e. it won't work if you can use different views in each action)
