public class HomeController : Controller
{
public ActionResult Index()
{
return this.View();
}
//跳转至WebSite
public ActionResult RedirectToGoogle()
{
return this.Redirect("http://www.google.com.hk/");
}
//跳转至Action
public ActionResult RedirectToEmployeesIndex()
{
return this.RedirectToAction("Index", "Employees");
}
//默认情况下,MVC 框架将 controller 类的所有公共方法都视为操作方法。
//如果您的 controller 类包含公共方法,并且您不希望它成为操作方法,
//则必须用 NonActionAttribute 特性标记该方法。
[NonAction]
public ActionResult NonActionMethod()
{
return this.View();
}
//处理未知Action异常
protected override void HandleUnknownAction(string actionName)
{
base.HandleUnknownAction(actionName);
}
}
