asp.net convert binary Base64 content into images and store them locally

The ext and data content in the form data of the headers of the website are received in the background and stored in the upload folder of the root directory of the website.

The code is as follows:

[HttpPost]
public ActionResult Images()
{
if (Request["ext"] == null || Request["data"] == null)
{
return Content("Error");
}
string ext = Request["ext"].ToString().Trim();
var btsdata = Convert.FromBase64String(Request["data"]);
string uploadDir = Server.MapPath("/Upload/" + Guid.NewGuid().ToString("D") + ext);
if (!Directory.Exists(uploadDir))
{
Directory.CreateDirectory(uploadDir);
}
using (Image img = Image.FromStream(new MemoryStream(btsdata)))
{
img.Save(uploadDir , ImageFormat.Jpeg);
}
return Content("Successed");
}
