In this article I will explain with an example, how to read (get) values from FormCollection inside Controller in ASP.Net MVC Razor.
FormCollection is a Key-Value pair collection and the value of each submitted Form field can be accessed using its Name attribute value.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 
Controller
The Controller consists of two Action methods.
Action method for handling GET operation
Inside this Action method, simply the View is returned.
 
Action method for handling POST operation
Inside this Action method, the values of both the TextBoxes are fetched using the FormCollection i.e. Request.Form collection using their Name attribute values.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Index(FormCollection form)
    {
        string name = form["Name"];
        string country = form["Country"];
        return View();
    }
}
 
 
View
The View consists of an HTML Form which has been created using the Html.BeginForm method with the following parameters.
ActionName – Name of the Action. In this case the name is Index.
ControllerName – Name of the Controller. In this case the name is Home.
FormMethod – It specifies the Form Method i.e. GET or POST. In this case it will be set to POST.
There are two TextBoxes. The TextBox for the Name value is a simple HTML INPUT element while the TextBox for the Country value is created using Html.TextBox helper function.
There’s also a Submit Button at the end of the Form and when the Button is clicked, the Form is submitted.
@{
    Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width"/>
    <title>Index</title>
</head>
<body>
    @using (Html.BeginForm("Index", "Home", FormMethod.Post))
    {
        <table cellpadding="5">
            <tr>
                <td>Name:</td>
                <td><input type="text" name="Name"/></td>
            </tr>
            <tr>
                <td>Country:</td>
                <td>@Html.TextBox("Country")</td>
            </tr>
        </table>
        <br/>
        <input type="submit" value="Submit"/>
    }
</body>
</html>
