任何人都曾经成功上传文件到WordPress使用他们的休息API？我可以创建媒体，但内容不上传时，我从WordPress管理检查。这里是代码上传它

public async Task<Author> UpdateProfilePicture(byte[] imageSource, string filename)
        {
            try
            {
                var url = Constants.BaseEndpoint + "/media";
                var header = ServiceHelpers.GetOauthHeader(url, "POST");
                var followCategory = string.Empty;
                using (var httpClient = new HttpClient())
                {

                    httpClient.DefaultRequestHeaders.Add("Authorization", header);
                    var requestContent = new MultipartFormDataContent();
                    var imageContent = new ByteArrayContent(imageSource);
                    imageContent.Headers.ContentType = MediaTypeHeaderValue.Parse("image/jpeg");
                    imageContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
                    {
                        FileName = filename + ".jpg"
                    };
                    requestContent.Add(imageContent);
                    var response = await httpClient.PostAsync(url, requestContent);
                    if (response.IsSuccessStatusCode)
                    {
                        var rawResponse = await response.Content.ReadAsStringAsync();
                        var parsedResponse = JsonConvert.DeserializeObject<Author>(rawResponse);
                        return parsedResponse;
                    }
                    throw new Exception("Not success");
                }
            }
            catch (Exception ex)
            {
            }
        }
