I am trying to resize image using bitmap from Memorystream and save to directory. It works on the first run but if i try to update the image second time i am getting ArgumentException.
public IActionResult UpdatePhoto(int id, IFormFile file)
{
var company = _context.Companies.FirstOrDefault(x => x.Id == id);
var image = company.Logo;
var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/companies", image);
if (System.IO.File.Exists(path))
{
System.IO.File.Delete(path);
}
ResizeImage(file, file.FileName);
company.Logo = file.FileName;
_context.Companies.Update(company);
_context.SaveChanges();
return RedirectToAction(nameof(Index));
}
I am getting error in Resize Method
public void ResizeImage(IFormFile file, string FileName)
{
using (var memoryStream = new MemoryStream())
{
file.CopyToAsync(memoryStream);
Bitmap original = (Bitmap)Image.FromStream(memoryStream);
Bitmap processed = new Bitmap(original,new Size(300,300));
var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/companies", FileName );
processed.Save(path);
}
you shouldn't be using any of the async
methods inside the methods which are not awaitable
. updating your code to following should fix the issue.
public void ResizeImage(IFormFile file, string FileName)
{
using (var memoryStream = new MemoryStream())
{
file.CopyTo(memoryStream);
Bitmap original = (Bitmap)Image.FromStream(memoryStream);
Bitmap processed = new Bitmap(original,new Size(300,300));
var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot/companies", FileName );
processed.Save(path);
}
}
