Silverlight将图片转换为byte的实现代码

byte[] staticByte;//全局byte，为将byte转换为Image

  private void OpenImage()
  {
   OpenFileDialog imageFile = new OpenFileDialog()
   {
    Filter = "Jpeg Files (*.jpg)|*.jpg|All Files(*.*)|*.*"
   };
   if (imageFile.ShowDialog() == true)
   { 
    System.IO.Stream fileStream=imageFile.File.OpenRead();
    byte[] imageByte=new byte[fileStream.Length];//设置byte的长度为文件流的长度
    fileStream.Read(imageByte,0,imageByte.Length);//将文件流信息读取到byte数组中
    staticByte = imageByte;//将读取好的byte数组保存到全局
    byteTextBox.Text=UTF8Encoding.UTF8.GetString(imageByte,0,imageByte.Length);//将byte数组显示到前台
   }
  }

private void button1_Click(object sender, RoutedEventArgs e)
  {
   OpenImage();
   MemoryStream memoryStream = new MemoryStream(staticByte,0,staticByte.Length);//将byte转换为内存流
   BitmapImage img = new BitmapImage();
   img.SetSource(memoryStream);//设置BitmapImage的源为内存流
   this.image1.Source = img;//显示图片
  }
