Without Using MVC like I am Using Webforms in WebApi Controller

Hi Tarun,

Follow these steps:Step1: In your ASP.NET Web Form application, right-click on the project in the Solution Explorer and select "Add" > "Controller...".
Step2: In the "Add Controller" dialog, select "MVC 5 Controller - Empty" and give the controller a name (e.g. "SampleController").
Step3: Click "Add" to create the controller.
Step4: In the "SampleController.cs" file that was created, add the following code:
 

using System.Web.Mvc;

public class SampleController : Controller
{
    // GET: Sample
    public ActionResult Index()
    {
        return View();
    }

    // POST: Sample
    [HttpPost]
    public ActionResult Index(FormCollection collection)
    {
        // Process the form data here
        return View();
    }
}

This code defines a controller called "SampleController" with two methods: "Index()" and "Index(FormCollection collection)". The first method is a GET method that returns a view, and the second method is a POST method that processes form data.

Step5: To test the controller with Postman, open Postman and create a new request.
Step6: In the request URL field, enter the URL of your ASP.NET Web Form application followed by "/Sample" (e.g. "http://localhost:12345/Sample").
Step7: Select the HTTP method "POST" and go to the "Body" tab.
Step8: Select "x-www-form-urlencoded" as the body type and enter some form data in the "Key" and "Value" fields.
Step9: Click "Send" to send the request to your ASP.NET Web Form application.
Step10: In the SampleController.cs file, set a breakpoint in the POST method to verify that it is being called.
Step11: Run the application and send the request again. The breakpoint should be hit, allowing you to debug the POST method and verify that the form data is being processed correctly.
