smtp.Host = "localhost";
smtp.Port = 25;
Do you have an SMTP server running on your local system? If not then you will not be able to send any mail. Google for "ASP.NET SMTP" and you will find samples that show how to do it correctly.

@Richardd Thank for your help is brings confident. I did find Email-SMTP on IIS on my computer it running, but the message is not sending.
|
|
|
|
|
I use a tool called SMTP4DEV to catch SMTP messages. If the message makes it to the tool, the fault is not in the code but the configuration of the SMTP server.
Ah don't lean on me man, cause you can't afford the ticket

Is there a particular reason you are using smtp on your local machine? Use a known working smtp provider from your ISP\webhost\network admin and if the code works using that then the problem is how you've configured your smtp server, so is not a programming question.

I am working with ASP.NET MVC 4 using Visual Studio 2015 community edition, and IIS 8.. I am beginner in this technology..
I created login page,
In my Login controller (action Index), I put return RedirectToAction("Index", "Home") to redirect the page when users enter correct username and password.. it works when I debug/run it in visual studio environment.. but when I publish it (let say the name is MyPublishedWeb), create application in IIS, and browse it, the URL will look like this: localhost/MyPublishedWeb/Login/Index
The problem is when I login succesfully, it redirects me to localhost/Home/Index, instead of localhost/MyPublishedWeb/Home/Index, and it gives error..
But when I change RedirectToAction() to Redirect(), it work both in Visual Studio environment and IIS..
What do I miss?
Why RedirectToAction() doesn't work in IIS application?

Without knowing your routes, you can use "/" as the url as it normally defaults to Home/Index

I writing a project about product management. Now I want scan barcode of a product when I import/export to store. Can you help me?
|
|
|
|
|
|
|
Most scanners are fairly straightforward devices which read a barcode and return a string containing the actual product number. The issue you need to consider is where the scanner will be connected. If you are trying to do this into a website then how will the users get access to the scanner?

I'm having a hard time finding anything on this on the internet possible because I don't how to word the question properly.
So I'm reading the Chapter on Routing in Professional ASP.NET MVC 5 and on the second page they have a list of requirements for high-quality URLs. One bullet point is that a URL must be hackable, that is the end of the URL can be hacked off and still work. So I am currently adding handling for this into the controllers of a test project but I can't figure out how to do something.
For example, say I have a controller
public class DepartmentController : Controller {}
With a Details action
public ActionResult Details(int? id)
{
}
I did figure out out that by making the parameter nullable, the controller doesn't error when passed a URL like: http://www.somesite.com/Department/Details that is lacking a parameter therefore fulfilling the hackable requirement. My question is on handling it.
All of the examples I can find pretty much mirrors this:
public ActionResult Details(int? id)
{
if (id == null)
{
return RedirectToAction("FourOhFourError", "Errors", null);
}
else
{
{
}
What I would like to know how to do is to return nothing. Is there a way not to return a redirect or is that impossible with an HTTP GET (i.e. the server must return something to the client)?
I found this which, turns out, is the same as returning null:
return new EmptyResult();
but this just redirects the browser to an empty page. Is there a way to not do anything and have the browser stay on the same page or is that not how the HTTP protocol works?
if (Object.DividedByZero == true) { Universe.Implode(); }

How about returning a specific view?
public ActionResult Details(int? id)
{
if (id == null)
{
return View("EmptyPage");
}
}
That would render the view located in ~/Views/Department/EmptyPage.cshtml
If you wanted to render a view from a different folder, you should be able to pass the app-relative path of the view:
return View("~/Views/Common/EmptyPage.cshtml");

What I am trying to figure out is how to not redirect at all. Let me try to expand a bit. From the end user point of view, say they browse to the URL http//:www.somesite.com/Departments/Details/5. Now, for some reason they backspace the '/5' off the end of the URL and hit enter. Is there a way to have their browser stay on the same page without redirecting or is that not possible. Handling the null parameter in the controller and returning a redirect to another page seems to be the only answer unless a session state is introduced which, to me, is defeating the whole purpose of making MVC stateless.
if (Object.DividedByZero == true) { Universe.Implode(); }

But returning a specific view doesn't redirect. It just displays that view.

try
return null;
or get the calling url from the request context and redirect to it
|
|
|
|
|
Using the request context to get the calling URL, didn't think of that. Can you provide a little code snippet on I how I do that?
if (Object.DividedByZero == true) { Universe.Implode(); }
|
|
|
|
|
string requestUrl = System.Web.HttpContext.Current.Request.Url.ToString();
|
|
|
|
|
Ah, just the same as with web forms. Thanks.
if (Object.DividedByZero == true) { Universe.Implode(); }
|
|
|
|
|
The ideal thing is that you won't hit that endpoint again from the originating url.
you could also try to return a PartialViewResult where the Content is set to a blank string ""
|
|
|
|
|
This seems a lot harder than if you were using AJAX and return PartialView().
|
|

I know. I was just asking if there was a way to not return anything from a [HttpGet] controller action that would normally return a View. It would appear to be impossible to just not return anything. I am beginning to think that it might be a part of the HTTP standard that a GET message from the client must return something from the server but I am not that knowledgeable on the particulars of the HTTP protocol.
if (Object.DividedByZero == true) { Universe.Implode(); }

No, not out of the box. The closest way to return nothing from an ActionResult returning method is the aforementioned EmptyResult.
That said, there is a way to do something similar by adding a route and a void method.
RouteConfig.cs
...
routes.MapRoute(
"DetailOverload",
"Department/Details",
new { controller = "Department", action = "VoidDetails" }
);
routes.MapRoute(
name: "Default",
url: "{controller}/{action}/{id}",
defaults: new { controller = "Home", action = "Index", id = UrlParameter.Optional }
);
DepartmentController.cs
public void VoidDetails()
{
}
public ActionResult Details(int id)
{
}
This is basically the .NET MVC baked-in way to modify action calls.
