Web API Multipart form data: how to read form data into a string, instead of save as file

In my controller I use code below to process multipart form data:

    string root = HttpContext.Current.Server.MapPath("~/App_Data");
    if (!Directory.Exists(root))
    {
        throw new QLApplicationException("Error ...");
    }
    MultipartFormDataStreamProvider provider = new MultipartFormDataStreamProvider(root);
     Task<HttpResponseMessage> task = Request.Content.ReadAsMultipartAsync(provider).ContinueWith<HttpResponseMessage>

This works fine except that it only saves the form data into a file at /App_Data. What I need however, is to get the data into a string in my program so I don't have to read it out again from the file. How can I do that? Thanks in advance!

Just to clarify, MultipartFormDataStreamProvider only saves any uploaded files into the file system. If you are looking to access the form values, you can do provider.FormData to get them.

If you are looking to access the uploaded file itself in-memory without saving it as a file on the drive, then you can use MultipartMemoryStreamProvider which reads all uploaded parts of the incoming request into memory. You can access each of this part by accessing the HttpContents property on the provider.
