forgive me if this question is too silly or already asked I googled a lot but I didnt get anything I want. I need to pass a byte array to server side using ajax but its not working as planned my current code is given below

var bytes = [];



for (var i = 0; i < data.length; ++i) {

    bytes.push(data.charCodeAt(i));

}



$.ajax({

    url: '/Home/ImageUpload',

    dataType: 'json',

    type: 'POST',

    data:{ data:bytes},

    success: function (response) {

        alert(hi);

    }

});

Upload Method

    [HttpPost]

    public ActionResult ImageUpload(byte[] data)

    {

                ImageModel newImage = new ImageModel();

                ImageDL addImage = new ImageDL();

                newImage.ImageData = data;

                addImage.AddImage(newImage);

                return Json(new { success = true });



    }

Better do this:

$.ajax({

    url: '/Home/ImageUpload',

    dataType: 'json',

    type: 'POST',

    data:{ data: data}, //your string data

    success: function (response) {

        alert(hi);

    }

});

And in controller:

[HttpPost]

    public ActionResult ImageUpload(string data)

    {

        var bytes = System.Text.Encoding.UTF8.GetBytes(data);

        //other stuff

    }
