<DxFileInput FilesUploading="OnFilesUploading" />

@code {
    async Task OnFilesUploading(FilesUploadingEventArgs args) {
        foreach (var file in args.Files) {
            var lastModified = file.LastModified;
            // ...
            /* The following code is intended for demonstration purposes only.
            Do not read a stream directly in memory to avoid performance and security-related issues. */
            using var stream = new System.IO.MemoryStream();
            await file.OpenReadStream(file.Size).CopyToAsync(stream);
        }
    }
}
