Hello

Use the web client UploadProgressChanged event

C#

private void cmdBrowseAndUpload_Click(object sender, EventArgs e)
        {
            string fileName = string.Empty;
            using (var dlg = new OpenFileDialog())
            {
                dlg.Filter = "All Files|*.*";
                if (dlg.ShowDialog(this) == DialogResult.OK)
                {
                    fileName = dlg.FileName;
                }
            }
            string url = string.Format(@"https://apis.live.net/v5.0/me/skydrive/my_documents/files/{0}?access_token={1}",
                Path.GetFileName(fileName), access_token);
            using (var client = new WebClient())
            {
client.UploadProgressChanged += new UploadProgressChangedEventHandler(client_UploadProgressChanged);
                client.UploadDataAsync(new Uri(url), "PUT", ImageToByteArray(fileName));
            }
        }

C#

void client_UploadProgressChanged(object sender, UploadProgressChangedEventArgs e)
       {
           //To do you code here.
           //Progress changed code here
       }
