Blazor Server: Attempting to take files from InputFile into an Email attachment - file-upload

Question

I am currently trying to get the files received from InputFile and attach it as an email attachment. I followed this website to get my InputFile with the progress bar: https://www.meziantou.net/file-upload-with-progress-bar-in-blazor.htm.
I have tried various options such as converting the file to byte array, using memory stream, and using a file stream but I do not have a path to copy the file too. Here's my code currently on what I am trying to accomplish. The Email is sent through SMTP client and that works perfectly without the attachments.
private async ValueTask LoadFiles(InputFileChangeEventArgs e)
{
var files = e.GetMultipleFiles(maximumFileCount: 100);
filesList = e.GetMultipleFiles(maximumFileCount: 100);
var startIndex = uploadedFiles.Count;
// Add all files to the UI
foreach (var file in files)
{
var progress = new FileUploadProgress(file.Name, file.Size);
uploadedFiles.Add(progress);
}
await using var timer = new Timer(_ => InvokeAsync(() => StateHasChanged()));
timer.Change(TimeSpan.FromMilliseconds(500), TimeSpan.FromMilliseconds(500));
// Upload files
byte[] buffer = System.Buffers.ArrayPool<byte>.Shared.Rent(4096);
try
{
foreach (var file in files)
{
MemoryStream ms = new MemoryStream();
using var stream = file.OpenReadStream(maxAllowedSize: 10 * 1024 * 1024);
while (await stream.ReadAsync(buffer) is int read && read > 0)
{
uploadedFiles[startIndex].UploadedBytes += read;
file.OpenReadStream().CopyTo(ms);
var fileBytes = ms.ToArray();
Attachment fileAttch = new Attachment(new MemoryStream(fileBytes), file.ContentType);
message.Attachments.Add(fileAttch);
var readData = buffer.AsMemory().Slice(0, read);
}
startIndex++;
}
}
finally
{
System.Buffers.ArrayPool<byte>.Shared.Return(buffer);
// Update the UI with the final progress
StateHasChanged();
}
}
When using the debugger, I noticed that the try block breaks whenever I try to copy the file into MemoryStream. I am not sure why. Any help or solutions would be greatly appreciated.
Thank you
I have tried copying the file/buffer into the memory stream but the try block breaks. I have tried to use file stream without success. I am either missing something I am unaware of or I am not implementing the code correctly.
