Save form-data in webapi C#

Question

I have the following code in Angular 2 for a form-data post method:

    upload(event) {
      let files: FileList = event.target.files;
      let formData = new FormData();
      for (let i = 0, f; f = files[i]; i++) {
        formData.append('attachment', files[i], f.name);
      }
     //call the angular http method
     this.http.
       .post(URL, formData)
       .map((res:Response) =>
          res.json()).subscribe(
             (success) => {
             alert(success._body);
          },
       (error) => alert(error))
      }
   }

It works perfectly by sending everything I’d like, my problem is now in creating the C#API, what kind will I get on the Formdata-compatible back? How do I manipulate it? Is it possible to save it in the bank? If not, how to save it in a folder? I appreciate all the help!

I used this in Webapi in C# and it worked very well. I got this information a while back from Stackoverflow himself here: https://stackoverflow.com/questions/27965568/webapi-file-uploading-without-writing-files-to-disk

public async Task<IHttpActionResult> UploadFile()
{
    if (!Request.Content.IsMimeMultipartContent())
    {
        return StatusCode(HttpStatusCode.UnsupportedMediaType);
    }        

    var filesReadToProvider = await Request.Content.ReadAsMultipartAsync();

    foreach (var stream in filesReadToProvider.Contents)
    {
        var fileBytes = await stream.ReadAsByteArrayAsync();
    }
}
