ASP.NET MVC3默认提供了11种ActionResult的实现

 

在System.Web.Mvc命名空间 ActionResult ContentResult EmptyResult FileResult HttpStatusCodeResult HttpNotFoundResult HttpUnauthorizedResult JavaScriptResult JsonResult RedirectResult RedirectToRouteResult ViewResultBase PartialViewResult

ViewResult

示例代码:

public class ActionResultController : Controller

{

public ActionResult Index()

{

return View();

}

public ActionResult ContentResult()

{

return Content("Hi, 我是ContentResult结果");

}

public ActionResult EmptyResult()

{

//空结果当然是空白了!

//至于你信不信, 我反正信了

return new EmptyResult();

}

public ActionResult FileResult()

{

var imgPath = Server.MapPath("~/demo.jpg");

return File(imgPath, "application/x-jpg", "demo.jpg");

}

public ActionResult HttpNotFoundResult()

{

return HttpNotFound("Page Not Found");

}

public ActionResult HttpUnauthorizedResult()

{

//未验证时,跳转到Logon

return new HttpUnauthorizedResult();

}

public ActionResult JavaScriptResult()

{

string js = "alert(\"Hi, I'm JavaScript.\");";

return JavaScript(js);

}

public ActionResult JsonResult()

{

var jsonObj = new

{

Id = 1,

Name = "小铭",

Sex = "男",

Like = "足球"

};

return Json(jsonObj, JsonRequestBehavior.AllowGet);

}

public ActionResult RedirectResult()

{

return Redirect("~/demo.jpg");

}

public ActionResult RedirectToRouteResult()

{

return RedirectToRoute(new {

controller = "Hello", action = ""

});

}

public ActionResult ViewResult()

{

return View();

}

public ActionResult PartialViewResult()

{

return PartialView();

}

//禁止直接访问的ChildAction

[ChildActionOnly]

public ActionResult ChildAction()

{

return PartialView();

}

//正确使用ChildAction

public ActionResult UsingChildAction()

{

return View();

}

}
