How to upload Multiple Files(more than 1000 files) to Web API.

4y1.3k.NET

I have used "IFormFileCollection" to upload files to web API, but it fails when uploading many files (say 1000s). I can only upload 10 files less than 5Mb to my web API at once. But in the Azure portal Blob, i can upload as many as 50 files(at least > 20 files at once). How this is achieved?. I am planning to write a command line to interrate files and upload from local machine to web API 10 files at a time, but this means that to run my command line the machine should have .net installed. Is there a way to achive this in .net

I have my Web API similar to - https://www.c-sharpcorner.com/article/upload-and-download-multiple-files-using-web-api/
But i am not able to upload more than 10 files with this approach in single request. I wanted to know how the azure portal is able to upload many files to blob storage.

1. var mpfdc = new MultipartFormDataContent();
2. mpfdc.Headers.ContentType.MediaType = "multipart/form-data";
4. // repeat this 10 times
5. await using var fs = new FileStream(sourceFileName, FileMode.Open, FileAccess.Read, FileShare.Read);
6. mpfdc.Add(new StreamContent(fs), "file", Path.GetFileName(sourceFileName));
8. var request = new HttpRequestMessage()
9. {
10. RequestUri = Uri.TryCreate(myuri, UriKind.RelativeOrAbsolute,
11. out Uri uri)
12. ? uri
13. : null,
14. Method = HttpMethod.Post,
15. Content = mpfdc
16. };
18. var response = await _httpClient.SendAsync(request, stoppingToken);
19. response.EnsureSuccessStatusCode();
