.NET Core HttpClient - Uploading multiple files through a multipart/form-data POST

 Yesterday I blogged about uploading files through Postman. Let's now move on to the real application and implement the client API to upload the files using the .NET Core HttpClient.

The code is not that hard but I'm sharing it here just a reminder for myself:

	var sourceFile ="ExampleDocument.docx";
	using var form = new MultipartFormDataContent();
	using var fileContent = new ByteArrayContent(await File.ReadAllBytesAsync(sourceFile));
	fileContent.Headers.ContentType = MediaTypeHeaderValue.Parse("multipart/form-data");
	form.Add(fileContent, "files", fileName:sourceFile);
	var response = await Client.PostAsync("/convert/office", form);
	response.EnsureSuccessStatusCode();
