How to pass data from a form in a view to another controller with C# MVC? - forms

Question

If I have a form that needs to use a textbox input like as below:
#{
if(IsPost){
username = Request.Form["username"]
}
}
<form action="Home/Index" method="post">
<input type="text" name="username" />
<input type="submit" value="submit" />
</form>
The controller is something like below,
public class HomeController : Controller
{
public ActionResult Index (string username) {
if (string username != string.Empty)
{
Console.WriteLine("Your username is " + username);
}
return View();
}
}
Seems like the data is not being passed from the post method. When I hit submit the URL that it requests is Home/Home/Index, which is not were the controller(HomeController) action is located, it should be Home/Index, and use the HomeController right?
What if I need to pass this data to a different controller that has an Index for the action, like UserController?

In this instance, you're missing a slash!
<form action="/Home/Index" method="post">
<input type="text" name="username" />
<input type="submit" value="submit" />
</form>
But when using asp.net mvc, you should use Url.Content with the home directory character to ensure that if your site is deployed in a sub-directory of the site, the correct root will be found. So use:
<form action="#Url.Content("~/Home/Index")" method="post">
<input type="text" name="username" />
<input type="submit" value="submit" />
</form>
