MVC 3 -ASP.NET重定向到不同的视图

In MVC 3-ASP.NET, I am validating the permission level on the page in the controller. If the user is authorised to see the page then I am using the following code to render it but I don't how to redirect to a new view if not authorised

在MVC 3-ASP.NET中,我正在验证控制器页面上的权限级别。如果用户有权查看该页面,那么我使用以下代码进行渲染,但如果未经授权,我不知道如何重定向到新视图

Could any one tell me how to display alert saying, you are not authorised to see the page and redirect to home page?

任何人都可以告诉我如何显示提醒说,您无权查看该页面并重定向到主页?

public ActionResult viewName()
if(userAuthorised)
{
return View()
}
else
{
    //Alert Message
    //Redirect to different view like Home Page..
}

Any examples please?

有什么例子吗?

Thank you

You have 2 choices. 1) Create a standard error view and return this in the else:

你有2个选择。 1)创建标准错误视图并在else中返回:

else
{
     ErrorModel viewModel = new ErrorModel(){Msg="Error"});
     return View("Error", viewModel);
}

2) Use a Redirect to Action which points at another Controller method which returns the Error View

2)使用指向另一个返回错误视图的Controller方法的Redirect to Action

else
{
   return RedirectToAction("BadUser");
}


public ViewResult BadUser()
{
     ErrorModel viewModel = new ErrorModel(){Msg="Error"});
     return View("Error", viewModel);
}
