using FileStream to save image but image is invalid - asp.net-mvc

Question

I'm getting an image from a base64 string, stored in a datatable. This string pulls successfully and is a valid base64 string, as I have tested it on free image decode websites and it decodes it back to the image I originally uploaded.
Now, I am trying to write the image to a file and no matter what I try, it fails to create the image file properly. The image only shows if I return it to a View as File(imageBytes, "image/jpeg")
Here is my code:
string imagepath = Path.Combine(Server.MapPath("~/Content"), client.ClientId + "_task" + task.TaskId + "_TaskReport.jpg");
byte[] imageBytes = Convert.FromBase64String(myDataTable.Rows[0].ItemArray[1].ToString()); // this works elsewhere, but for some reason only when returning the image to the view as a FileResult
using (var imageFile = new FileStream(imagepath, FileMode.Create))
{
imageFile.Write(imageBytes, 0, imageBytes.Length); // this line creates the bad image!
imageFile.Flush();
}
What is wrong with my code? Why does it work with the mvc FileResult and not when converting to an image?

Answer 1

Try this to write file
byte[] b= //Your Image File in bytes;
System.IO.File.WriteAllBytes(#"c:\data.jpg", b)

Answer 2

Try this,
[HttpPost]
public ActionResult FileUpload(HttpPostedFileBase file)
{
if (ModelState.IsValid)
{
try
{
if (file != null && file.ContentLength > 0)
{
System.IO.MemoryStream target = new MemoryStream();
file.InputStream.CopyTo(target);
byte[] data = target.ToArray();
}
}
catch (Exception ex)
{
throw;
}
return View("Index",model);
}
return View();
}
