using (FileStream attStream = new FileStream(FilePath, FileMode.Open, FileAccess.Read))
{

    var att = WitClient.CreateAttachmentAsync(attStream, filePathSplit[filePathSplit.Length – 1]).Result; // upload the file

    JsonPatchDocument patchDocument = new JsonPatchDocument();

    patchDocument.Add(new JsonPatchOperation()
    {
        Operation = Operation.Add,
        Path = “/relations/-“,
        Value = new
        {
            rel = “AttachedFile”,
            url = att.Url,
            attributes = new { comment = “Comments for the file “ + filePathSplit[filePathSplit.Length – 1] }
