调用WebService的方法读取图片

切克瑙 2014-03-21 10:42:17

读取照片没做过，不了解。这是网上查找的资料做的，但客户段要怎么写，实在搞不出来了救命..
WebService里读取方法的代码



        [WebMethod]

        public byte[] GetImage(int attachment_source_id, int attachment_type)

        {

            C_Attachment item = GetAttachment(attachment_source_id, attachment_type);

            string fullPath = GetFullPath(item);

            if (String.IsNullOrEmpty(fullPath))

            {

                throw new ArgumentNullException("文件路径不能为空！");

            }

            else

            {

                return GetBinaryImage(fullPath);

            }

        }



public C_Attachment GetAttachment(int attachment_source_id, int attachment_type) 

        {

            return attachment.GetAttachment(attachment_source_id, attachment_type);

        }



 private string GetFullPath(C_Attachment item) 

        {

            //图片的根目录 /UploadPath/

            string rootPath = ConfigurationManager.AppSettings["UploadPath"];

            return Server.MapPath(rootPath + "/" + item.Attachment_path);

        }

我写的客户端的代码【但是不对】



TPWScreenInDoor.ScreenInDoorSoapClient _screenIn = new TPWScreenInDoor.ScreenInDoorSoapClient();

            var item = _screenIn.GetListByScreenInDoor(tbCode.Text);



            #region 读取前几个站点拍摄的照片

            TPWAttachment.AttachmentServiceSoapClient atta = new TPWAttachment.AttachmentServiceSoapClient();

            C_Attachment _att = new C_Attachment();

            byte[] attachemnt = atta.GetImage(item.Attachment_source_id, item.Attachment_type);

            #region

            //using (FileStream fileStream = new FileStream(_att.Attachment_path, FileMode.OpenOrCreate, FileAccess.ReadWrite))

            //{

            //    byte[] attachemnt = atta.GetImage(_att.Attachment_source_id, _att.Attachment_type);

            //    byte[] bytes = new byte[1024];

            //    int r = fileStream.Read(attachemnt, 0, attachemnt.Length);

            //    while (r > 0)

            //    {

            //        fileStream.Write(attachemnt, 0, r);

            //        Console.Write("*");

            //        r = fileStream.Read(attachemnt, 0, attachemnt.Length);

            //    }

            //} 

            #endregion

            Image img = null;

            for (int i = 0; i < attachemnt.Length - 1; i++)

            {

                MemoryStream ms = new MemoryStream(attachemnt[i]);

                img = Image.FromStream(ms);

            }

            pbIndoor.Image = img;

            #endregion



            this.tbCode.Text = item.Tv_code;

            this.tbBuyCompany.Text = item.Ts_buycompany_text;

            this.tbCoalkind.Text = item.Ts_coalkind_text;

            this.tbVelhideNumber.Text = item.Tv_vehicle_number;

照片有多张，我客户端应该怎么写...实习生求救...大神们救命呀

循环atta.GetImage，传不同的id，得到不同的图片

GetImage一次只得一张图片吧， MemoryStream ms = new MemoryStream(attachemnt); ***************************************************************************** 签名档： http://feiyun0112.cnblogs.com/

嗯应该怎么做呢在客户端

客户端的代码我重新粘一下


TPWScreenInDoor.ScreenInDoorSoapClient _screenIn = new TPWScreenInDoor.ScreenInDoorSoapClient();
            var item = _screenIn.GetListByScreenInDoor(tbCode.Text);

            TPWAttachment.AttachmentServiceSoapClient atta = new TPWAttachment.AttachmentServiceSoapClient();
            C_Attachment _att = new C_Attachment();
            byte[] attachemnt = atta.GetImage(item.Attachment_source_id, item.Attachment_type);
            
            Image img = null;
            for (int i = 0; i < attachemnt.Length - 1; i++)
            {
                MemoryStream ms = new MemoryStream(attachemnt[i]);
                img = Image.FromStream(ms);
            }
            pbIndoor.Image = img;
            #endregion

            this.tbCode.Text = item.Tv_code;
