How to save multiple files at the same time.

I tried the following but its nit working.

IFormFile file = document.DocumentNameOne;
IFormFile file2 = document.DocumentNameTwo;
IFormFile file3 = document.DocumentNameThree;
var webRoot = _env.WebRootPath;
var path = Path.Combine(
Directory.GetCurrentDirectory(), webRoot + "/Documents/",
file.FileName);
var pathTwo= Path.Combine(
Directory.GetCurrentDirectory(), webRoot + "/Documents/",
file.FileName);
var pathThree = Path.Combine(
Directory.GetCurrentDirectory(), webRoot + "/Documents/",
file.FileName);
using (var stream = new FileStream(pathTwo, FileMode.Create))
{
file.CopyTo(stream);
stream.Close();
}
using (var stream1 = new FileStream(pathThree, FileMode.Create))
{
stream1.Position = 0;
file2.CopyTo(stream1);
}
using (var stream2 = new FileStream(path, FileMode.Create))
{
stream2.Position = 0;
file3.CopyTo(stream2);
}

Saving all files exactly same time is not possible, but you can implement simultaneously operations by using async method...

Try using CopyToAsync instead of CopyTo.

Hey,

To save multiple files you can use below code

design code (File upload control)

AllowMultiple="true" ID="fileupload_" runat="server" />

.cs code

HttpFileCollection _HttpFileCollection = Request.Files;
String[] images_name = new String[_HttpFileCollection.Count]; // Array of image name
for (int i = 0; i < _HttpFileCollection.Count; i++)
{
      HttpPostedFile _HttpPostedFile = _HttpFileCollection[i];
      if (_HttpPostedFile.ContentLength > 0)
      {
         String filename = Path.GetFileName(_HttpPostedFile.FileName);
         String filenameWithoutExt = Path.GetFileNameWithoutExtension(filename);
         int last_id = feedModel.getStoryLastId();
         String NewPath = filename.Replace(filenameWithoutExt, user_id + "_" + last_id + "_" + i); //change file name
         _HttpPostedFile.SaveAs(Server.MapPath("/images/Other/" + Path.GetFileName(NewPath)));

         images_name[i] = Path.GetFileName(NewPath);
      }
}

Thanks

Its a web app. Locally it does copy the files but on server it doesnt copy the files.
