用Web Service实现客户端图片上传到网站

由于项目需要,通过本地客户端,把图片上传到网站.通过webservice.

这是客户端代码:

        private void btnimg_Click(object sender, EventArgs e)
         {
             this.yanzheng();
             mylocalhost.MySoapHeader myheader = new mylocalhost.MySoapHeader();///这是soapheader
             mylocalhost.MyWebService myService = new mylocalhost.MyWebService();//调用服务
             myService.MySoapHeaderValue = myheader;
             openFileDialog1.ShowDialog();
             pictureBox1.Image = Image.FromFile(openFileDialog1.FileName);
             string name=this.textBox1.Text.ToString();
             myService.CreateFiles(name, PhotoImageInsert(pictureBox1.Image));//图片名字,图片字节流
             MessageBox.Show(openFileDialog1.FileName);//文件本地路径
             MessageBox.Show("保存成功");
         }

         /// <summary>
         /// 把Image对象转化成byte[]字节流
         /// </summary>
         /// <param name="imgPhoto">Image对象,就是上传的那张图片</param>
         /// <returns>byte[]字节流</returns>
         public byte[] PhotoImageInsert(System.Drawing.Image imgPhoto)
         {
             //将Image转换成流数据，并保存为byte[]
             MemoryStream mstream = new MemoryStream();
             imgPhoto.Save(mstream, System.Drawing.Imaging.ImageFormat.Png);
             byte[] byData = new Byte[mstream.Length];
             mstream.Position = ;
             mstream.Read(byData, , byData.Length);
             mstream.Close();
             return byData;
         }

服务端代码:

     /// <summary>
     /// 把服务中的字节流生成图片文件的方法
     /// </summary>
     /// <param name="imgName">图片名字</param>
     /// <param name="FormData">数据流</param>
     [System.Web.Services.Protocols.SoapHeader("header")]//用户身份验证的soap头
     [WebMethod(Description = "生成图片", EnableSession = true)]
     public  void CreateFiles(string imgName, byte[] FormData)
     {
         //图片生成路径
         string path = HttpContext.Current.Server.MapPath("") + @"/../JajaWeixinQianduanWeb/UpLoadCaiPinImages/" + imgName + ".jpg";
         BinaryWriter bw = new BinaryWriter(File.Create(path, FormData.Length, FileOptions.Asynchronous));
         bw.Write(FormData);//得到上传的那张图片,并保存
         bw.Close();
     }
