Add Controller 專門處理錯誤請求。

public class ErrorsController : Controller
{
	//
	// GET: /ErrorsController/
	[HttpGet]
	public ActionResult Http404()
	{
		return View();
	}

	[HttpGet]
	public ActionResult Http403()
	{
		return View();
	}

	[HttpGet]
	public ActionResult General()
	{
		return View();
	}
}

 

在Global.asax 中添加應用程式錯誤的處理函示:

protected void Application_Error()
{
	var exception = Server.GetLastError();
	var httpException = exception as HttpException;
	Response.Clear();
	Server.ClearError();
	var routeData = new RouteData();
	routeData.Values["controller"] = "Errors";
	routeData.Values["action"] = "General";
	routeData.Values["exception"] = exception;
	Response.StatusCode = 500;
	if (httpException != null)
	{
		Response.StatusCode = httpException.GetHttpCode();
		switch (Response.StatusCode)
		{
			case 403:
				routeData.Values["action"] = "Http403";
				break;
			case 404:
				routeData.Values["action"] = "Http404";
				break;
		}
	}

	IController errorsController = new ErrorsController();
	var rc = new RequestContext(new HttpContextWrapper(Context), routeData);
	errorsController.Execute(rc);
}

 

撰寫錯誤畫面(404 Not Found)

@{
    ViewBag.Title = "404 Not Found";
}

<body style="color: #444; margin:0;font: normal 14px/20px Arial, Helvetica, sans-serif; height:100%; background-color: #fff;">
    <div style="height:auto; min-height:100%; ">
        <div style="text-align: center; width:800px; margin-left: -400px; position:absolute; top: 30%; left:50%;">
            <h1 style="margin:0; font-size:150px; line-height:150px; font-weight:bold;">404</h1>
            <h2 style="margin-top:20px;font-size: 30px;">
                Not Found
            </h2>
            <p>The resource requested could not be found on this server!</p>
        </div>
    </div>
</body>
