xml图片的生成-ASP教程,XML相关

string xmlfilename=strtempxml;
     xmltextwriter xw=new xmltextwriter(xmlfilename,encoding.utf8);
     xw.writestartdocument();
     xw.writestartelement(“image”);
     xw.writestring(photo);
     xw.writeendelement();
     xw.writeenddocument();
     xw.flush();
     xw.close();
     //写入xml成功

     //从xml读入到图片
     xmltextreader xr=new xmltextreader(strtempxml);
     byte[] buffer = new byte[buffersize];
     int readbyte=0;
     //create a file to write the bmp back.  jpgnewfile表示新图片
     this.jpgpackfile=this.jpgpackfile.replace(“.jpg”,j+”.jpg”);
     filestream filenew = new filestream(this.jpgpackfile, filemode.create, fileaccess.readwrite, fileshare.readwrite);
     binarywriter bw = new binarywriter(filenew);
     xr.movetocontent();   
     do
     {
      readbyte=xr.readbase64(buffer, 0, buffersize);
      bw.write(buffer, 0, readbyte);
     } while(readbyte>=buffersize);

     bw.flush();    
     bw.close();    
     filenew.close();
     xr.close();//关闭 !!!!
