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:

 1        private void btnimg_Click(object sender, EventArgs e) 2         { 3             this.yanzheng(); 4             mylocalhost.MySoapHeader myheader = new mylocalhost.MySoapHeader();///这是soapheader 5             mylocalhost.MyWebService myService = new mylocalhost.MyWebService();//调用服务 6             myService.MySoapHeaderValue =http://www.mamicode.com/ myheader; 7             openFileDialog1.ShowDialog(); 8             pictureBox1.Image = Image.FromFile(openFileDialog1.FileName); 9             string name=this.textBox1.Text.ToString();10             myService.CreateFiles(name, PhotoImageInsert(pictureBox1.Image));//图片名字,图片字节流11             MessageBox.Show(openFileDialog1.FileName);//文件本地路径12             MessageBox.Show("保存成功");13         }14 15         /// <summary>16         /// 把Image对象转化成byte[]字节流17         /// </summary>18         /// <param name="imgPhoto">Image对象,就是上传的那张图片</param>19         /// <returns>byte[]字节流</returns>20         public byte[] PhotoImageInsert(System.Drawing.Image imgPhoto)21         {22             //将Image转换成流数据，并保存为byte[]23             MemoryStream mstream = new MemoryStream();24             imgPhoto.Save(mstream, System.Drawing.Imaging.ImageFormat.Png);25             byte[] byData = http://www.mamicode.com/new Byte[mstream.Length];26             mstream.Position = 0;27             mstream.Read(byData, 0, byData.Length);28             mstream.Close();29             return byData;30         }

服务端代码:

 1     /// <summary> 2     /// 把服务中的字节流生成图片文件的方法 3     /// </summary> 4     /// <param name="imgName">图片名字</param> 5     /// <param name="FormData">数据流</param> 6     [System.Web.Services.Protocols.SoapHeader("header")]//用户身份验证的soap头  7     [WebMethod(Description = "生成图片", EnableSession = true)] 8     public  void CreateFiles(string imgName, byte[] FormData) 9     {10         //图片生成路径11         string path = HttpContext.Current.Server.MapPath("") + @"/../JajaWeixinQianduanWeb/UpLoadCaiPinImages/" + imgName + ".jpg";12         BinaryWriter bw = new BinaryWriter(File.Create(path, FormData.Length, FileOptions.Asynchronous));13         bw.Write(FormData);//得到上传的那张图片,并保存14         bw.Close();15     }
