C#获取类以及类下的方法(用于Asp.Net MVC)

 1     public ActionResult GetControllerAndAction()
 2         List<Type> controllerTypes = new List<Type>();    //创建控制器类型列表
 3      var assembly = Assembly.Load("MySoft.UI");    //加载程序集
 4      controllerTypes.AddRange(assembly.GetTypes().Where(type => typeof(IController).IsAssignableFrom(type) && type.Name!="ErrorController"));    //获取程序集下所有的类，通过Linq筛选继承IController类的所有类型
 5      StringBuilder jsonBuilder = new StringBuilder();    //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
 6      jsonBuilder.Append("[");
 7      foreach (var controller in controllerTypes)//遍历控制器类
 8      {
 9          jsonBuilder.Append("{\"controllerName\":\"");
10          jsonBuilder.Append(controller.Name);
11           jsonBuilder.Append("\",\"controllerDesc\":\"");
12           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
13           jsonBuilder.Append("\",\"action\":[");
14           var actions = controller.GetMethods().Where(method => method.ReturnType.Name == "ActionResult");    //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
15           foreach (var action in actions)
16           {
17               jsonBuilder.Append("{\"actionName\":\"");
18               jsonBuilder.Append(action.Name);
19               jsonBuilder.Append("\",\"actionDesc\":\"");
20               jsonBuilder.Append((action.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute) == null ? "" : (action.GetCustomAttribute(typeof(DescriptionAttribute)) as DescriptionAttribute).Description);    //获取对Action的描述
21               jsonBuilder.Append("\"},");
22           }
23           jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
24           jsonBuilder.Append("]},");
25       }
26       jsonBuilder.Remove(jsonBuilder.Length - 1, 1);
27       jsonBuilder.Append("]");
28       return Content(jsonBuilder.ToString(),"json/text");t");
