Asp – how do i can swich the view based on the logged in user in mvc asp.net

asp.net-mvcauthentication

I need to either redirect user or show not authorized page according to usertype of the logged in user.

Here is some which would give you an idea.

public ActionResult Index()
{
    if (Request.Cookies["isadmin"].Value != "true")
        return View("NotAuthorized","Index");
    else
        return View();
}

Here I have created new view with NotAuthorized as view name and projectname.Models.NotAuthorized as strongly type view.

after building and running the project,it give me following error.

Parser Error Message: Could not load type 'System.Web.Mvc.ViewPage'.

Are you using the final version? Did you created the project using the VS template? Also, check your project references.

Asp.net-mvc – Can an ASP.NET MVC controller return an Image

Use the base controllers File method.

public ActionResult Image(string id)
{
    var dir = Server.MapPath("/Images");
    var path = Path.Combine(dir, id + ".jpg"); //validate the path for security or use other means to generate the path.
    return base.File(path, "image/jpeg");
}

As a note, this seems to be fairly efficient. I did a test where I requested the image through the controller (http://localhost/MyController/Image/MyImage) and through the direct URL (http://localhost/Images/MyImage.jpg) and the results were:

MVC: 7.6 milliseconds per photo
Direct: 6.7 milliseconds per photo

Note: this is the average time of a request. The average was calculated by making thousands of requests on the local machine, so the totals should not include network latency or bandwidth issues.
