            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("multipart/form-data"));

            MultipartFormDataContent content = new MultipartFormDataContent();
            content.Add(new StringContent("1"), "pageIndex");
            content.Add(new StringContent("25"), "pageSize");
            
            var result = client.PostAsync(url, content).Result.Content.ReadAsStringAsync().Result;
