    2,后台代码:

    public static string UploadFile()
            {
    
                var filelist = HttpContext.Current.Request.Files;
                if (filelist.Count == 0)
                    return Newtonsoft.Json.JsonConvert.SerializeObject(new { ResultCode = 0, ResultMsg = "上传失败" });
                string NewFiles = DateTime.Now.ToString("yyyyMM") + "ymall";
                List<AccessoryDTO> accessoryList = new List<AccessoryDTO>();
                for (int i = 0; i < filelist.Count; i++)
                {
                    var file = filelist[i];
    
                    string suffix = Path.GetExtension(file.FileName);
                    string fileName = Guid.NewGuid() + suffix.ToLower();
                    //string url = "";
    
                    byte[] buffer = new byte[file.InputStream.Length];
                    file.InputStream.Read(buffer, 0, (int)file.InputStream.Length);
                    Utility.Net.FtpArgs args = new Utility.Net.FtpArgs()

                        Userpwd = ConfigurationManager.AppSettings["ProductImg:FtpUserpwd2"],
                        RemoteDir = "/" + NewFiles + "/",
                        RemoteFileName = fileName,
                        UploadData = buffer
                    };
                    Utility.ReturnMessage rm = Utility.Net.CFTP.Upload(args);
                    if (!rm.Success)
                    {
                        return Newtonsoft.Json.JsonConvert.SerializeObject(new { ResultCode = 0, ResultObject = accessoryList, ResultMsg = "上传异常" });
                        //continue;
                    }
                        
    
                    AccessoryDTO dto = new AccessoryDTO();
                    dto.AccessoryFileType = file.ContentType;
                    if (dto.AccessoryFileType!= "image/jpeg"&& dto.AccessoryFileType != "image/png") //jpg
                    {
                        return Newtonsoft.Json.JsonConvert.SerializeObject(new { ResultCode = 0, ResultObject = accessoryList, ResultMsg = "请上传jpg,png格式!!" });
                    }
                    dto.AccessoryName = file.FileName;
                    dto.AccessorySize = file.ContentLength;
                    dto.AccessoryUrl = ConfigurationManager.AppSettings["ProductImg:HttpHost2"] + NewFiles + "/" + fileName;
                    dto.Sort = i;
                    accessoryList.Add(dto);
                }
                return Newtonsoft.Json.JsonConvert.SerializeObject(new { ResultCode = 1, ResultObject = accessoryList, ResultMsg = "上传成功!!" });
            }

    3,web配置

    1     <!--图上传FTP路径-->
    2     <add key="ProductImg:HttpHost2" value="ftp://192.168.10.32:99/" />
    3     <add key="ProductImg:FtpHost2" value="192.168.10.32" />
    4     <add key="ProductImg:FtpPort2" value="99" />
    5     <add key="ProductImg:FtpUserName2" value="" />
