{

        HttpPostedFile postfiles = FileUpload1.PostedFile;
        if (postfiles.ContentLength > 0)
        {
            System.IO.Stream iStream = postfiles.InputStream;
            byte[] filedata = new byte[postfiles.ContentLength];
            iStream.Read(filedata, 0, postfiles.ContentLength);
            postfiles.SaveAs(@"c:Temp" + postfiles.FileName);
            YouTubeRequestSettings settings = new YouTubeRequestSettings("AAA", youtube_DVkey, g_username, g_password);
            YouTubeRequest request = new YouTubeRequest(settings);
            Video newvideo = new Video();
            newvideo.Title = txtTitle.Text;
            newvideo.Tags.Add(new MediaCategory(category.SelectedItem.Text, YouTubeNameTable.CategorySchema));
            newvideo.Keywords = txtKeywords.Text;

            newvideo.Private = false;
            newvideo.Tags.Add(new MediaCategory(txtTitle.Text.Trim(), YouTubeNameTable.DeveloperTagSchema));
            newvideo.YouTubeEntry.Location = new Google.GData.Extensions.Location.GeoRssWhere(37, -122);
            newvideo.YouTubeEntry.MediaSource = new MediaFileSource(@"c:Temp" + postfiles.FileName, Video_type.SelectedItem.Text);
            try
            {
                Video result_video = request.Upload(youtubeaccount, newvideo);
                File.Delete(@"c:Temp" + postfiles.FileName);
                Response.Redirect("gallery.aspx");
            }
            catch (Google.GData.Client.GDataRequestException ex)
            {
                Response.Write(ex.ToString());
            }
            catch (Google.GData.Client.InvalidCredentialsException ex)
            {
                Response.Write("Invalid credentials" + ex.ToString());
            }
            catch(Exception ex)
            {
                Response.Write("Failed to upload!" + ex);
            }
        }
    }
