Extract file content from sfUploader

Question

Hello!

I have a third party document system in a Blazor API.

I am trying to send the file from the sfUploader to the api. The api does not have SyncFusion and can not. The api uses MinimalAPI and FastEndpoints.  I have the uploader in an sfDialog.  I don't want anything to send on the ValueChanged event.  I only want activity when the user clicks the OK button on the dialog.   Also, I am trying to avoid saving the file to disk as there is no need.  I am using the ValueChanged event to save the file in the args to a form level UploadFiles variable so I can use it on the OnValidModel event.  I don't see any other way to get the file.  The GetFilesDataAsync and GetFileDetails methods don't seem to contain the actual file.  Also, no matter which file object I uses - the UploadFile or Fileinfo, the RawFile property is always empty.  Assume for this example I'm sending a pdf.The steps I think are needed are:Convert file to byte arraySend to apiStream byte array back into a pdf.  (Save file as a test only)Put the pdf into the document system type variable.How do I get the pdf (or any type) of file) from the uploader and put it in a byte array?Thank you

I figured it out.  Here _uploadFile is an UploadFile type.  Now you can send the byte array to toe api.

byte[] fileBytes = null!;
  using (var stream = _uploadFile.File.OpenReadStream(_uploadFile.File.Size))
  {
    using (var reader = new MemoryStream())
    {
      await stream.CopyToAsync(reader);
      fileBytes = reader.ToArray(); 
      reader.Close();
    }
    stream.Close();
  }
