【MVC】获取项目中所有的控制器-试图

在C#中，实现动态获取类和方法主要通过反射来实现，要引用System.Reflection。

方法一：

public ActionResult GetControllerAndAction()
        {
            //创建控制器类型列表
            List<Type> controllerTypes = new List<Type>();
            
            //加载程序集
            var assembly = Assembly.Load("MPMS");

            //获取程序集下所有的类，通过Linq筛选继承IController类的所有类型
            controllerTypes.AddRange(assembly.GetTypes().Where(type => typeof(IController).IsAssignableFrom(type) && type.Name != "ErrorController"));

            //创建动态字符串，拼接json数据    注：现在json类型传递数据比较流行，比xml简洁
            StringBuilder jsonBuilder = new StringBuilder();    
            jsonBuilder.Append("[");

            //遍历控制器类
            foreach (var controller in controllerTypes)
            {
                jsonBuilder.Append("{\"controllerName\":\"");
                jsonBuilder.Append(controller.Name);
                jsonBuilder.Append("\",\"controllerDesc\":\"");
                jsonBuilder.Append((controller.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute) == null ? "" : (controller.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute).Description);
                
                //获取对控制器的描述Description
                jsonBuilder.Append("\",\"action\":[");

                //获取控制器下所有返回类型为ActionResult的方法，对MVC的权限控制只要限制所以的前后台交互请求就行，统一为ActionResult
                var actions = controller.GetMethods().Where(method => method.ReturnType.Name == "ActionResult");    
                foreach (var action in actions)
                {
                    jsonBuilder.Append("{\"actionName\":\"");
                    jsonBuilder.Append(action.Name);
                    jsonBuilder.Append("\",\"actionDesc\":\"");
                    jsonBuilder.Append((action.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute) == null ? "" : (action.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute).Description);    //获取对Action的描述
                    jsonBuilder.Append("\"},");
                }
                jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
                jsonBuilder.Append("]},");
            }
            jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
            jsonBuilder.Append("]");
            return Content(jsonBuilder.ToString());
        }

方法二：

/// <summary>
        /// 通过反射得到所有可用的action
        /// </summary>
        /// <returns></returns>
        public static List<string> GetALLPageByReflection()
        {
            List<string> actions = new List<string>();
            var asm = System.Reflection.Assembly.GetExecutingAssembly();
            System.Collections.Generic.List<Type> typeList = new List<Type>();
            var types = asm.GetTypes();
            foreach (Type type in types)
            {
                string s = type.FullName.ToLower();
                if (type.Name.StartsWith("AccountCont")) continue;
                if (s.StartsWith("mvctmm.controllers.") && s.EndsWith("controller"))
                    typeList.Add(type);
            }
            typeList.Sort(delegate (Type type1, Type type2) { return type1.FullName.CompareTo(type2.FullName); });
            foreach (Type type in typeList)
            {
                //Response.Write(type.Name.Replace("Controller","") + "<br/>\n");
                System.Reflection.MemberInfo[] members = type.FindMembers(System.Reflection.MemberTypes.Method,
                System.Reflection.BindingFlags.Public |
                System.Reflection.BindingFlags.Static |
                System.Reflection.BindingFlags.NonPublic |        //【位屏蔽】
                System.Reflection.BindingFlags.Instance |
                System.Reflection.BindingFlags.DeclaredOnly,
                Type.FilterName, "*");
                foreach (var m in members)
                {
                    if (m.DeclaringType.Attributes.HasFlag(System.Reflection.TypeAttributes.Public) != true)
                        continue;
                    string controller = type.Name.Replace("Controller", "");
                    string action = m.Name;
                    string url = "/" + controller + "/" + action;
                    actions.Add(url);
                }
            }
            return actions;
        }
