Jaimin Shethiya · Answer

Hello Vishakha, You can try the below way. [ApiController] [Route("api/[controller]")] public class CalculateController : ControllerBase { [HttpPost] public IActionResult Post(AddRequest addRequest) { int result = Add(addRequest); return Ok(result); } private int Add(AddRequest addRequest) { return addRequest.Num1 + addRequest.Num2; } } public class AddRequest { public int Num1 { get; set; } public int Num2 { get; set; } } Calling from the postman

Check this: using Microsoft.AspNetCore.Mvc; namespace MyWebApi.Controllers { [ApiController] [Route("api/[controller]")] public class CalculateController : ControllerBase { [HttpPost("add")] public ActionResult Add([FromBody] NumbersToAdd numbers) { int result = numbers.Number1 + numbers.Number2; return Ok(result); } } public class NumbersToAdd { public int Number1 { get; set; } public int Number2 { get; set; } } } Or [ApiController] [Route("api/[controller]")] public class CalculateController : ControllerBase { [HttpPost] [Route("add")] public IActionResult Add([FromForm] int num1, [FromForm] int num2) { int result = num1 + num2; return Ok(result); } }

using System.Web.Http; namespace WebApiDemo.Controllers { public class AddController : ApiController { [HttpPost] public IHttpActionResult AddNumbers([FromBody] Numbers numbers) { if (numbers == null) { return BadRequest("Invalid input"); } int sum = numbers.Number1 + numbers.Number2; return Ok(sum); } } public class Numbers { public int Number1 { get; set; } public int Number2 { get; set; } } } using System.Web.Http; namespace WebApiDemo { public static class WebApiConfig { public static void Register(HttpConfiguration config) { // Web API routes config.MapHttpAttributeRoutes(); config.Routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "api/{controller}/{action}/{id}", defaults: new { id = RouteParameter.Optional } ); } } } Test the API : Run your application, and you can test the API using a tool like Postman or any other REST client. HTTP Method : POST URL : http://localhost:YourPortNumber/api/add/addnumbers Headers : Content-Type: application/json Body : Raw JSON { "Number1": 5, "Number2": 10 }
