上传图片到Twitter

Question

    public TwitterResponse UpdateStatus(string message, String fileName, String contentType, byte[] image)
    {
        RestClient client = new RestClient
        {
            Authority = TwitterConstants.Authority,
            VersionPath = TwitterConstants.Version

        };

        message = HttpUtility.HtmlEncode(message);

        client.AddHeader("content-type", "multipart/form-data");

        client.AddField("status", message);
        client.AddField("media[]", Convert.ToBase64String(image) + ";filename=" + fileName + ";type=" + contentType);

        RestRequest request = new RestRequest
        {
            Credentials = this.Credentials,
            Path = "statuses/update_with_media.json",
            Method = Hammock.Web.WebMethod.Post

        };

        return new TwitterResponse(client.Request(request));
    }

为了排除可能的其他问题，我可以使用update.json方法成功地将状态更新发布到Twitter。

我还尝试使用client.addfile方法和Fiddler，看起来一切都就绪了。但我不断得到的错误信息是

{"errors":[{"code":195,"message":"Missing or invalid url parameter"}]}

using (var stream = new FileStream(imagePath, FileMode.Open))
            {
                var result = service.SendTweetWithMedia(new SendTweetWithMediaOptions
                {
                    Status = message,
                    Images = new Dictionary<string, Stream> { { "john", stream } }
                });
                lblResult.Text = result.Text.ToString();
            }
