Upload file in BOX using BOX API using C#

Question

I have BOX account and in API document

curl https://upload.box.com/api/2.0/files/content \ -H "Authorization: Bearer ACCESS_TOKEN" \ -F filename=@FILE_NAME \ -F parent_id=PARENT_FOLDER_ID

I am stuck with this filename and parent_id how to pass the filename and parent_id

i have tried lots of way, but nothing is working for me.

Following is the code:

        httpWReq.Method = "POST";
        httpWReq.Headers.Add("Authorization", "Bearer ");
        httpWReq.ContentType = "multipart/form-data";


        //{\"parent_id\":\""+parentID +"\"}

        //byte[] file = File.ReadAllBytes(postData);

        httpWReq.ContentLength = data.Length;

        using (Stream reqStream = httpWReq.GetRequestStream())
        {
            reqStream.Write(data, 0, data.Length);
                //reqStream.Close();
        }
        using (HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse())
        {
            //Console.WriteLine("HTTP/{0} {1} {2}", response.ProtocolVersion, (int)response.StatusCode, response.StatusDescription);
            response.Close();

        }

Vaibhav,

Please see example of how official Box C# SDK is doing upload: https://github.com/box/box-windows-sdk-v2/blob/master/Box.V2/Managers/BoxFilesManager.cs

Is there any reason why you don't want to use Box Windows SDK?

The Box.com sdk uses several projects that will not load unless you are developing in a Windows 8.1 environment. The SDk presents extremely robust objects and methods and combined with a limited selection of projects to explore along with .net framework deprecation, it becomes extremely intimidating especially considering that all those objects are are wrappers for straight calls you can make yourself. Combined with box api documentation that lacks context for people completely unfamiliar with the entire process and OAuth, the entire process can be quite difficult to follow, at best.
