Upload Video on Dailymotion with C#?

Following is the complete code to upload video with C# code programmatically but it does not contain the code for the objects that are deserialized from JSON. Dailymotion doesn't provide c# code to upload video with c# in its API documentation that's why the way to upload is adopted from CURL sample code.

static void Main(string[] args)

{

var accessToken = GetAccessToken();

Authorize(accessToken);

Console.WriteLine("Access token is " + accessToken);

var uploadUrl = GetFileUploadUrl(accessToken);

Console.WriteLine("Posting to " + uploadUrl);

var response = GetFileUploadResponse(fileToUpload, accessToken, uploadUrl);

Console.WriteLine("Response:\n");

Console.WriteLine(response + "\n");

Console.WriteLine("Publishing video.\n");

var uploadedResponse = PublishVideo(response, accessToken);

Console.WriteLine(uploadedResponse);

Console.WriteLine("Done. Press enter to exit.");

Console.ReadLine();
