In this article I will explain with an example, how to get Request parameters inside Controller’s Action method in ASP.Net MVC Razor.
Note: For beginners in ASP.Net MVC, please refer my article ASP.Net MVC Hello World Tutorial with Sample Program example.
 
 
Model
Following is a Model class named PersonModel with four properties i.e. PersonId, Name, Gender and City.
public class PersonModel
{
    ///<summary>
    /// Gets or sets PersonId.
    ///</summary>
    public int PersonId { get; set; }
 
    ///<summary>
    /// Gets or sets Name.
    ///</summary>
    public string Name { get; set; }
 
    ///<summary>
    /// Gets or sets Gender.
    ///</summary>
    public string Gender { get; set; }
 
    ///<summary>
    /// Gets or sets City.
    ///</summary>
    public string City { get; set; }
}
 
 
Controllers
Source 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
This Action method handles the Form Submission when the Button is clicked.
Note: For details about Form Post in MVC, please refer my article ASP.Net MVC: Form Submit (Post) example.
 
When the Send Button is clicked, the QueryString Parameters along with value are passed to the RedirectToAction method.
public class HomeController : Controller
{
    // GET: Home
    public ActionResult Index()
    {
        return View();
    }
 
    [HttpPost]
    public ActionResult Send()
    {
        //Send Model object in Query String to another Controller.
        return RedirectToAction("Index", "Person Details", new { PersonId = 1, Name = "Mudassar Khan", Gender = "Male", City = "Mumbai" });
    }
}
 
Destination Controller
The Controller consists of the following Action method.
Action method for handling GET operation
Inside this Action method, the QueryString Parameters are received as parameters in the Action method.
The values are then set into an object of PersonModel class and then the object is sent to the View.
public class PersonDetailsController : Controller
{
    // GET: Person Details
    public ActionResult Index(int personId, string name, string gender, string city)
    {
        PersonModel person = new PersonModel
        {
            PersonId = personId,
            Name = name,
            Gender = gender,
            City = city
        };
        return View(person);
    }
}
 
 
Views
Source 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.
The Form consists of a Submit Button 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("Send", "Home", FormMethod.Post))
    {
        <input type="submit" value="Send"/>
    }
</body>
</html>
 
Destination View
Inside the View, in the very first line the PersonModel class is declared as Model for the View.
The View consists of an HTML Table which is used for displaying the values of the properties of the PersonModel class.
@model Extract_QueryString_MVC.Models.PersonModel
@{
    Layout = null;
}
 
<!DOCTYPE html>
 
<html>
<head>
    <meta name="viewport" content="width=device-width"/>
    <title>Index</title>
</head>
<body>
    <table cellpadding="0" cellspacing="0">
        <tr>
            <th colspan="2" align="center">Person Details</th>
        </tr>
        <tr>
            <td>PersonId: </td>
            <td>@Model.PersonId</td>
        </tr>
        <tr>
            <td>Name: </td>
            <td>@Model.Name</td>
        </tr>
        <tr>
            <td>Gender: </td>
            <td>@Model.Gender</td>
        </tr>
        <tr>
            <td>City: </td>
            <td>@Model.City</td>
        </tr>
    </table>
</body>
</html>
