I can can get picture by Razor '@Action' but with Ajax Can't. I write in controller:
public ActionResult getCommodityPic()
{
var f= File(Server.MapPath("~/App_Data/CommodityPics/eee/1") + ".jpg", "image/jpg");
return f;
}
and in java script :
$(document).ready(function () {
ShowCommodities();
getCommodityPic();
});
function getCommodityPic() {
$.ajax({
url: '@Url.action("getCommodityPic")',
type: 'Get',
dataType: 'image/jpg',
success: function (Data, Status, jqXHR) {
$('#img1').attr('src', Data);
}
});

$.ajax({
url: '@Url.Action("DownloadPic", "MyController")',
contentType: 'application/json; charset=utf-8',
datatype: 'json',
data: {
id: Id
},
type: "GET",
success: function (Data, Status, jqXHR) {
if (Data != "") {
alert("Empty");
return;
}
window.location ='@Url.Action("DonloadPic","Mycontroller")';
}
});
in Controller:
public ActionResult DownloadPic(int? id)
{
Lesson l = new Lesson();
l = db.Lesson.Single(p => p.id == id);
if (l.picture == null)
{
string targetFolder = System.Web.HttpContext.Current.Server.MapPath("~/Image/book-03.jpg");
byte[] img = System.IO.File.ReadAllBytes(targetFolder);
return File(img, "image/jpg");
}
return File(l.picture, "image/jpg");
}

If you want to display the image dynamically, then try this. You may not need an Ajax call for this.
$('#img1').html('<img src="getCommodityPic" />')
If you want to process the image (read its raw binary) then this answer should help - https://stackoverflow.com/a/20048852/6352160
