C#使用RestSharpPost请求接口上传文件并附带参数

引用关键dll：RestSharp.dll

调用接口上传

 public JsonResult PutImgAdd()
        {
            try
            {
                string folder = System.Web.HttpContext.Current.Request.Form["folder"].ToString();
                HttpFileCollection fileList = System.Web.HttpContext.Current.Request.Files;//获取图片集合

                if (fileList != null && fileList.Count > 0)
                {
                    var client = new RestClient("接口地址");
                    client.Timeout = -1;
                    var request = new RestRequest(Method.POST);
                    request.AddParameter("folder", "Cert");//参数

					//可能存在多张图片循环添加
                    for (int i = 0; i < fileList.Count; i++) {

                        HttpPostedFile postfile = fileList[i];
                        Image drimg = Image.FromStream(postfile.InputStream);
                        byte[] bytes = GetB
