I have created a rest api, where i have to pass data as array in below format. but when i pass data using postman i am getting an error.

{ "notificationid": [
  "BC716385-5D65-4E0F-8987-070D6C42F629","B4425D6C-1028-4164-8C82-0BB9324F48D8"

[HttpPost, Route("MarkAllAsRead")]
public async Task<IActionResult> NotificatiRead([FromBody]string [] NotificationId)
{
    try
    {
        ModelState.Remove("PatientId");
        if (!ModelState.IsValid)
        {
            return BadRequest(new
            {
                Status = false,
                Message = string.Join(Environment.NewLine, ModelState.Values
                                    .SelectMany(x => x.Errors)
                                    .Select(x => x.ErrorMessage))
            });
        }
        var res = await _notificationService.ReadNotificationlist(NotificationId);
        return res.Status ? StatusCode(StatusCodes.HTTP_OK, res) : StatusCode(StatusCodes.HTTP_DATANOTMATCHED, res);
    }
    catch (Exception ex)
    {
        Logger.AddErrorLog(ControllerContext.ActionDescriptor.ControllerName, "Notificationupdate", User.Identity.Name, ex);
        return StatusCode(StatusCodes.HTTP_INTERNAL_SERVER_ERROR, ex.Message);

This way you can pass array.

You will need to make use of Anonymous dynamic objects and in order to Deserialize, you need to use Newtonsoft JSON library available at Nuget.

View

@{
    Layout = null;
}

<!DOCTYPE html>

<html>
<head>
    <meta name="viewport" content="width=device-width" />
    <title>Index</title>
    <style type="text/css">
        body { font-family: Arial; font-size: 10pt; }
    </style>
</head>
<body>
    <form id="form1">
    <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
    <script type="text/javascript">
        $("body").on("click", "#btnSubmit", function () {
            var data = {};
            data.NotificationIds = new Array();
            data.NotificationIds.push("BC716385-5D65-4E0F-8987-070D6C42F629");
            data.NotificationIds.push("B4425D6C-1028-4164-8C82-0BB9324F48D8");
            $.ajax({
                url: '/api/AjaxAPI/PostData',
                type: 'POST',
                data: { "": JSON.stringify(data) },
                dataType: "json",
                success: function (response) {
                    alert(response.NotificationIds[0]);
                    alert(response.NotificationIds[1]);
                }
            });
        });
    </script>
</body>
</html>

Controller

using System.IO;
using System.Net;
using System.Net.Http;
using System.Web;
using System.Web.Http;
using Newtonsoft.Json;
namespace jQuery_Web_API_without_Model_MVC.Controllers
{
    public class AjaxAPIController : ApiController
    {
        [Route("api/AjaxAPI/PostData")]
        [HttpPost]
        public object PostData([FromBody] string json)
        {
            dynamic data = JsonConvert.DeserializeObject(json);
            return new { NotificationIds = data.NotificationIds };
        }
    }
}
