Web Service (1): Using Web Service to implement client image upload to Web site

Because the project needs, through the local client, the picture is uploaded to the website. Through WebService.

This is the client code:

1        Private voidBtnimg_click (Objectsender, EventArgs e)2         {3              This. Yanzheng ();4Mylocalhost. Mysoapheader MyHeader =NewMylocalhost. Mysoapheader ();///this is SoapHeader .5Mylocalhost. MyWebService MyService =NewMylocalhost. MyWebService ();//Invoke Service6Myservice.mysoapheadervalue =MyHeader;7 Openfiledialog1.showdialog ();8pictureBox1.Image =Image.FromFile (openfiledialog1.filename);9             stringName= This. textBox1.Text.ToString ();TenMyservice.createfiles (name, Photoimageinsert (pictureBox1.Image));//picture name, picture byte stream OneMessageBox.Show (Openfiledialog1.filename);//file Local Path AMessageBox.Show ("saved successfully"); -         } -  the         /// <summary> -         ///Convert Image object to byte[] byte stream -         /// </summary> -         /// <param name= "Imgphoto" >Image object, which is the uploaded image</param> +         /// <returns>byte[] Byte stream</returns> -          Public byte[] Photoimageinsert (System.Drawing.Image imgphoto) +         { A             //convert image to stream data and save as byte[] atMemoryStream Mstream =NewMemoryStream (); - Imgphoto.save (Mstream, System.Drawing.Imaging.ImageFormat.Png); -             byte[] Bydata =NewByte[mstream. Length]; -Mstream. Position =0; -Mstream. Read (Bydata,0, bydata.length); - Mstream. Close (); in             returnBydata; -}

Service-Side code:

1     /// <summary>2     ///How to generate picture files from the byte stream in the service3     /// </summary>4     /// <param name= "Imgname" >Picture name</param>5     /// <param name= "FormData" >Data Flow</param>6[System.Web.Services.Protocols.SoapHeader ("Header")]//SOAP headers for user authentication7[WebMethod (Description ="Create a picture", enablesession =true)]8      Public  voidCreatefiles (stringImgname,byte[] FormData)9     {Ten         //Picture Generation Path One         stringPath = HttpContext.Current.Server.MapPath ("") +@"/.. /jajaweixinqianduanweb/uploadcaipinimages/"+ Imgname +". jpg"; ABinaryWriter bw =NewBinaryWriter (file.create (Path, formdata.length, fileoptions.asynchronous)); -Bw.
