HttpMultipartFormDataFactory

A small library for creating multipart/form-data content from flat objects.

Usage

Create an instance of the MultipartFormDataFactory class or use MultipartFormDataFactory.Default static field, then pass it a request object:

var multipartFormDataFactory = new MultipartFormDataFactory();
var content = await multipartFormDataFactory.Create(request, token);

This will return a System.Net.Http.MultipartFormDataContent instance. Later is can be used in http client instance like this:

var response = await _httpClient.PostAsync(url, content, token);

IFormFile abstraction should be used for files.
