In web forms we create web methods that serves like API service and could be consume using ajax calls.

[System.Web.Services.WebMethod]
public static string GetCurrentTime(string name)
{
    return "Hello " + name + Environment.NewLine + "The Current Time is: "
        + DateTime.Now.ToString();
}

dear @Tuhin paul  brother 

i was told that i should not take the controller i have to take normal class and it should work as a controller   this is my requirement pls help me find out  when i hit postman it checks the class

1. Create a new ASP.NET Web Application project in Visual Studio.

2. Add a new Web API Controller class to the project.

3. In the Controller class, create methods for the GET and POST operations.

[HttpGet]
public IHttpActionResult GetData()
{
    // Get data from database or other data source
    var data = new List { "Data 1", "Data 2", "Data 3" };
    
    // Return the data as JSON
    return Json(data);
}

[HttpPost]
public IHttpActionResult AddData([FromBody]string newData)
{
    // Add the new data to the database or other data source
    // ...
    
    // Return a success message
    return Ok("Data added successfully");
}

4. Build and run the project.

5. Test the GET and POST methods using Postman or any other REST client. To test the GET method, send a GET request to the URL of the controller action (e.g., http://localhost/api/Controller/GetData). To test the POST method, send a POST request to the URL of the controller action with the new data as the request body (e.g., http://localhost/api/Controller/AddData).

6. Verify that the response from the server is as expected.

Hello Tarun,

Please refer this one,

https://www.aspsnippets.com/Articles/Call-Consume-Web-API-in-Code-Behind-in-ASPNet-using-C.aspx#:~:text=In%20order%20to%20add%20a,suitable%20name%20and%20click%20OK.

public partial class MyWebForm : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!IsPostBack)
        {
            // Perform actions on initial GET request
        }
    }

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        // Process user input and perform necessary actions on the server
    }
}

The Page_Load event handler is called when the Web Form is first loaded on a GET request. The IsPostBack property is used to determine whether the request is a POSTback (i.e., the result of a form submission) or an initial GET request. 
The btnSubmit_Click event handler is called when the user clicks the Submit button on the form. This method is used to process the user input and perform any necessary actions on the server.

1. Create a new Web Forms application in Visual Studio.
2. Add a new Web Form to the project.
3. Add server controls to the Web Form to accept user input.
4. In the code-behind file of the Web Form, add event handlers for the GET and POST methods.
5. In the GET event handler, retrieve data from the server and populate the server controls with the data.
6. In the POST event handler, process user input and perform any necessary actions on the server.
