ActionResult是ContentResult类、ViewResult类、JsonResult类等所有的Controller中返回值类型的基类
using System.Collections.Generic;using System.Linq;using System.Web;using System.Web.Mvc;using System.Web.Mvc.Ajax;using System.IO;namespace DemoRC.Controllers{    public class DemoController : Controller    {        /// <summary>        /// http://localhost:1847/Demo/ContentResultDemo        /// </summary>        /// <returns></returns>        public ActionResult ContentResultDemo()        {            string contentString = "ContextResultDemo! 请查看 Controllers/DemoController.cs文件,里面包含所有类型ActionResult的用法.";            return Content(contentString);        }        /// <summary>        /// http://localhost:1847/Demo/EmptyResultDemo        /// </summary>        /// <returns></returns>        public ActionResult EmptyResultDemo()        {            return  new EmptyResult();        }        /// <summary>        /// http://localhost:1847/Demo/FileContentResultDemo        /// </summary>        /// <returns></returns>        public ActionResult FileContentResultDemo()        {            FileStream fs = new FileStream(Server.MapPath(@"/resource/Images/1.gif"), FileMode.Open, FileAccess.Read);            byte[] buffer = new byte[Convert.ToInt32(fs.Length)];            fs.Read(buffer, 0, Convert.ToInt32(fs.Length) );            return File(buffer, @"image/gif");        }        /// <summary>        /// http://localhost:1847/Demo/FilePathResultDemo        /// </summary>        /// <returns></returns>        public ActionResult FilePathResultDemo()        {            //可以将一个jpg格式的图像输出为gif格式            return File(Server.MapPath(@"/resource/Images/2.jpg"), @"image/gif");        }        /// <summary>        /// http://localhost:1847/Demo/FileStreamResultDemo        /// </summary>        /// <returns></returns>        public ActionResult FileStreamResultDemo()        {                        FileStream fs = new FileStream(Server.MapPath(@"/resource/Images/1.gif"), FileMode.Open, FileAccess.Read);            return File(fs, @"image/gif");        }        /// <summary>        /// http://localhost:1847/Demo/HttpUnauthorizedResultDemo        /// </summary>        /// <returns></returns>        public ActionResult HttpUnauthorizedResultDemo()        {            return new HttpUnauthorizedResult();        }        /// <summary>        /// http://localhost:1847/Demo/JavaScriptResultDemo //mvc ajax脚本引入才会起作用        /// </summary>        /// <returns></returns>        public ActionResult JavaScriptResultDemo()        {            return JavaScript(@"alert(""Test JavaScriptResultDemo!"")");        }        /// <summary>        /// http://localhost:1847/Demo/JsonResultDemo        /// </summary>        /// <returns></returns>        public ActionResult JsonResultDemo()        {            var tempObj = new { Controller = "DemoController", Action = "JsonResultDemo" };            return Json(tempObj);        }        /// <summary>        /// http://localhost:1847/Demo/RedirectResultDemo        /// </summary>        /// <returns></returns>        public ActionResult RedirectResultDemo()        {            return Redirect(@"http://localhost:1847/Demo/ContentResultDemo");        }        /// <summary>        /// http://localhost:1847/Demo/RedirectToRouteResultDemo        /// </summary>        /// <returns></returns>        public ActionResult RedirectToRouteResultDemo()        {            return RedirectToAction(@"FileStreamResultDemo");        }        /// <summary>        /// http://localhost:1847/Demo/PartialViewResultDemo        /// </summary>        /// <returns></returns>        public ActionResult PartialViewResultDemo()        {            return PartialView();        }        /// <summary>        /// http://localhost:1847/Demo/ViewResultDemo        /// </summary>        /// <returns></returns>        public ActionResult ViewResultDemo()        {            //如果没有传入View名称, 默认寻找与Action名称相同的View页面.            return View();        }    }}</span>
