需要反射的DLL里的一个类：

namespace ElegantWM.WebUI.Areas.Admin.Controllers{    [Description("功能模块管理")]    public class ModuleController : BaseController    {        [Action]        [Description("根据系统编号，获取系统的功能模块")]        [HttpGet]        public string Get(Guid sysId)        {            ...            return json;        }        [Action]        [Description("新建功能模块")]        [HttpPost]        public JsonResult Create(WMS_Module module)        {           ...        }        [Action]        [Description("修改功能模块")]        [HttpPut]        public JsonResult Update(WMS_Module module)        {           ...        }        [Action]        [Description("删除功能模块")]        [HttpDelete]        public JsonResult Delete(WMS_Module module)        {            ...        }    }}

反射代码：

Assembly assembly = Assembly.LoadFrom(@"ElegantWM.WebUI.dll");            var types = assembly.GetTypes();            foreach (var type in types)            {                if (type.BaseType.Name == "BaseController")//如果是Controller                {                    var members = type.GetMethods();                    foreach (var member in members)                    {                        //获取HTTPAttribute                        IEnumerable
     
       atts = member.GetCustomAttributes();                        bool isAction = false;                        foreach (Attribute a in atts)                        {                            if (a.GetType().Name == "Action" || a.GetType().Name == "Page")                            {                                richTextBox1.AppendText(a.GetType().Name + "\r\n");                                isAction = true;                            }                            else if (a.ToString().Contains("System.Web.Mvc.Http"))                            {                                richTextBox1.AppendText(a.GetType().Name.Replace("Http", "").Replace("Attribute", "") + "\r\n");                            }                        }                        if (!isAction) continue;                                                //获取返回值                            　　　　　　　　　　　　　　richTextBox1.AppendText(member.ReturnType.Name + "\r\n");                        //获取方法说明                        object[] attrs = member.GetCustomAttributes(typeof(System.ComponentModel.DescriptionAttribute), true);                        if (attrs.Length > 0)                            richTextBox1.AppendText((attrs[0] as System.ComponentModel.DescriptionAttribute).Description + "\r\n");                                                //获取参数                        ParameterInfo[] param = member.GetParameters();                        StringBuilder sb = new StringBuilder();                        foreach (ParameterInfo pm in param)                        {                            sb.Append(pm.ParameterType.Name + " " + pm.Name + ",");                        }                        richTextBox1.AppendText("(" + sb.ToString().Trim(',') + ")" + "\r\n");                                                //获取方法名称                        richTextBox1.AppendText(member.Name + "\r\n");                        //获取类名                        richTextBox1.AppendText(member.DeclaringType.Name + "\r\n");                                                                       richTextBox1.AppendText("--------------------------\r\n");                    }                }            }
