.net后台使用PFile上传图片/文件

                 if (!file.HasFile)

               {

                  this.lablMsg.Text = "请选择要上传的图片！";
                  return;

                }

                Guid filekey = System.Guid.NewGuid();  //获取生成的key
                model.I_PATH = filekey.ToString();      //赋给表字段
                HttpPostedFile UploadFile = Request.Files["file"]; 
                byte[] bImg = new byte[0];     //声明字节型数据类型
                bImg = new byte[UploadFile.ContentLength]; //写入
                Stream imgStream = UploadFile.InputStream;  //输入流
                imgStream.Read(bImg, 0, UploadFile.ContentLength); //读取
                imgStream.Close();
                Phoebe.PFile.FileService.SaveFile(Path.GetFileName(UploadFile.FileName), bImg, model.I_PATH); //保存
